Briefly explain why sulfur and phosphorus can form complicated molecules, but nonmetals in period 2 tend to form only diatomic molecules

Answers

Answer:

see below

Explanation:

Sulfur and phosphorous can violate the octet rule and have an expanded octet, so molecules of these elements can contain more than eight valence electrons. In contrast, nonmetal elements in period 2 can't have an expanded octet because they don't have d orbitals. These elements must obey the octet rule and can hold only up to eight valence electrons. Period 2 elements can fill their outer orbitals by covalently bonding with one other atom of the same element.

When we discuss communication, we often first think of written and oral communication. Write one paragraph about a time when you found it easier to communicate with a graph than with text.

Answers

Answer:

There's a lot of answers.

Explanation:

Last year, I presented a paper on population growth in the United States between the years 1975 and 2015. The data involved numbers and figures. This data was difficult to present in textual format, so I turned to graphing. The graph helped me break down and simplify complex numerical data so my audience could more easily understand it.

A time when I found it easier to communicate with a graph than with text was when I wanted to make a presentation about the importance of education.

Communication simply means sending a message from one person to another person. Graphs can be used when one wants to make a visual representation of data.

I used graphs when I wanted to make a presentation about the importance of education. I wanted to show the audience how certain regions like the European countries are well developed than African countries. The graph was vital in visualizing this.

What is heart?

Heart is a muscular organ which is present in most of the animals , it is responsible for pumping blood via the blood vessels to the entire body.The blood which is pumped carries oxygen and nutrients along with it.Along with it on it's way back to heart it carries carbon dioxide to the lungs.

Heart has an approximate size of a closed fist and is present between the lungs in the middle compartment of the chest. It is divided in to for chambers , the upper chambers called atria and lower ones called ventricles.

The wall of the heart is made up of three layers : epicardium,myocardium and endocardium. It pumps blood with a rhythm which is determined by a group of cells which are called the pacemaker cells present in the sinoatrial node.

List the following elements in order of increasing atomic radius:
1. sulfur II. hydrogen III. strontium IV. iodine
V. oxygen

Answers

Answer:

sulfur

hydrogen

iodine

oxygen

strontium

Explanation:

An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements.

In general, the size of an atom will decrease as you move from left to the right of a certain period.

Order of increasing atomic radius:

O < H < S < I < Sr

Describe the trend of atomic radius.

The atomic radius measures the separation between an atom's nucleus and its farthest electrons.

The trend across a periodAtoms' atomic radii typically decrease from left to right.As electrons are added to the same primary energy level, protons are gradually added to the nucleus. Because of the increased positive charge on the nucleus, these electrons are gradually drawn closer to it. Atomic sizes shrink as the strength of attraction between nuclei and electrons grows.

The trend down the groupWithin a group, atoms' atomic radii typically increase from top to bottom. Again, the positive nuclear charge rises as the atomic number decreases inside a group. The number of major energy levels that are occupied is increasing as well, though. The orbitals from higher primary energy levels have greater sizes than the orbitals from lower principal energy levels. Atomic radius increases down a group as a result of the stronger impact of the major energy levels outweighing the increase in nuclear charge.

Which of the following substances has the highest melting point?
a. pentane b. nonane c. ethane d. butane

Answers

Nonane (b) has the highest melting point.

-----------------------------

A caveat: I'm assuming that we're dealing with the straight-chain isomers of these alkanes (specifically pentane and nonane). The straight-chain isomer of pentane (n-pentane, CH3-[CH2]3-CH3) has a melting point of -129.8 °C; the straight-chain isomer of nonane (n-nonane, CH3-[CH2]7-CH3) has a melting point of -53.5 °C. The pattern holds as you go down (or up): The more carbon atoms, the higher the melting point. So, in decreasing order of melting points here, you'd have the following: nonane > pentane > butane > ethane.

However, one structural isomer of pentane, neopentane, has a melting point of -16.4 °C, which is higher that the melting point of n-nonane despite neopentane having the same molecular formula as its straight-chain isomer. Of course, you're not to blame for coming up with this question; this is just some extra info to keep in mind.

If carbon lost one proton, what atom would be formed

Answers

Answer:

boron

Explanation:

boron has 5 protons and carbon has 6, so if carbon lost a proton, it would become boron since each element has a unique number of protons.

As each element has a different number of protons, boron has five and carbon has six, so if carbon lost one of its protons, it would change into boron.

What is proton ?

Every atom has a proton, a subatomic particle, in its nucleus. The particle possesses an electrical charge that is positive and opposite to the electron's.

In the reaction, a proton is forfeited. Keep in mind that when the number of protons changes, the atomic number also changes, creating a new element. Carbon-14 is the end result as a result. It is a new element, yet it has the same mass as nitrogen-14.

When carbon creates covalent bonds, pairs of electrons are shared between the atoms instead of being gained or lost as happens with chemical bonds. The ability of carbon to construct lengthy chains of atoms and so create intricate biological compounds is due in part to this feature.

Thus, If carbon lost one proton, boron atom would be formed.

A swimming pool, 10.0 m by 4.0 m, is filled with water to a depth of 3.0 m at a temperature of 20.2°C.

How much energy is required to raise the temperature of the water to 28.6°C?

Answers

Energy required : 4.23 x 10⁹ J

Further explanation  

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

Volume of water:

[tex]\tt V=L\times W\times H\\\\V=10\times 4\times 3=120~m^3[/tex]

mass of water :

ρ = 1000 kg/m³

[tex]\tt mass=\rho\times V\\\\mass=1000~kg/m^3\times 120~m^3=120,000~kg[/tex]

Heat required

c water = 4200 J/ kg ° C  

[tex]\tt Q=m.c.\Delta T\\\\Q=1.2\times 10^5\times 4200\times (28.6-20.2)\\\\Q=42336\times 10^5=4.23\times 10^9~J[/tex]

Answers

Answer:

35.45253819

Explanation:

(0.7578*34.96....)+(0.2422*36.96...)

Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate. The average atomic mass of Chlorine is 35.45g.

What is mass?

Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope.

Average atomic mass = (mass of first isotope× percent abundance of first isotope)+(mass of second isotope× percent abundance of second isotope)

Substituting the given values

Average atomic mass=(0.7578×34.96....)+(0.2422×36.96...)

Average atomic mass=35.45g

Therefore, the average atomic mass is 35.45g.

How many joules are contained in a snack cake that is labeled "230 Calories"?
(Hint: 1 Calorie - 1,000 calories, 1 cal - 4.184 J)
O A 9.62 X 102 J
B
9.62 X 1053
C. 54.9 J
5.49 X 10 to the power of 4

Answers

Answer:

9.62 × 10² J

Explanation:

In this problem, we need to convert 230 calories to joules. For this, we must know the conversion from calories to joules.

1 Calorie = 4.184 Joules

To find Joules in 230 calories, multiply 4.184 by 23. So,

230 Calorie = (230 × 4.184) Joules

= 962.32 Joules

or

230 Calories = 9.62 × 10² J

if the density of a bar of gold is 19.3g/cm^3and you cut it into four pieces , what is its density of each piece of gold

Answers

Density is an intrinsic property, so it is independent of the amount of substance present: one gold coin would have the same density as a solid gold boulder.

So if the density of gold is 19.3 g/cm³, the density of a bar of gold and the pieces into which the bar is cut would all be 19.3 g/cm³.

Considering the definition of density and intensive and extensive properties, the density of each piece of gold is 19.3 [tex]\frac{g}{cm^{3} }[/tex]

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Intensive properties are those that will remain unchanged even though the amount of matter varies, while extensive properties vary depending on the amount of matter in a body.

Density is an intensive property, so it is independent of the sample size. This is because the solute will be present in a certain proportion with respect to the solvent. That ratio will not change unless more solute or more solvent is added. Consequently, the concentration remains constant (concentration is an intensive property) and density too.

Finally, the density of each piece of gold is 19.3 [tex]\frac{g}{cm^{3} }[/tex]
