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.
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.

Explanation:
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
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]

Find the average atomic mass for Cl if 75.78% of Cl atoms are Cl-35 with a mass of 34.96885271 u and 24.22% are Cl-37 with a mass of 36.96590260 u.
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
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
So, the correct option is (A).

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

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.

If carbon lost one proton, what atom would be formed
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.
