Which [H+] value describes a neutral solution?

10−7 M


10−14 M


10−1 M


10−12 M

Answer:

30.2°F

Explanation:

Butane, the liquid that can be seen inside a transparent lighter, boils at a temperature slightly under the point at which water freezes. So why doesn't the butane in the lighter boil? Butane does indeed boil at about a degree below 32 degrees Fahrenheit, but this is true only at normal atmospheric pressure. (:

Answer:

Word Equation:

Zinc + Copper (II) nitrate → Copper + Zinc nitrate

Formula Equation:

Zn (s) + Cu(NO3)2 (aq) → Cu (s) + Zn(NO3)2 (aq)

Ionic Equation:

Zn (s) + Cu2+ (aq) → Zn2+ (aq) + Cu (s)

Description

A 1 gram granule of zinc metal was dropped into a test tube containing 10 cm

3

of clear blue copper nitrate solution (1 M). The zinc quickly began to react with the solution producing a clear green solution and a darker solid at the bottom of the test tube.

Explanation:

there are four (4)mole of Nh3 that react with N2

Answer: While the mass number is the sum of the protons and neutrons in an atom, the atomic number is only the number of protons. The atomic number is the value found associated with an element on the periodic table because it is the key to the element's identity.

Answer:

Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 2).

Answer:

0.0612 moles of O2 produced

Explanation:

     First we convert from grams of Potassium Chlorate to moles..

Amu = 122.5

5.00g / 122.5 g = 0.0408163265 moles of Potassium Chlorate

    Now we need to use the chemical equation to find the ratio of Potassium Chlorate to Oxygen... But first, we need to balance it

Original Chemical Equation : KClO3 = O2 + KCl

Balanced Chemical Equation : 2KClO3 = 3O2 + 2KCl

     Now we will use the balanced chemical equation to find the ratio of Potassium Chlorate to oxygen (in order to convert to moles of oxygen for our answer)

We can see that for every 2 moles of Potassium Chlorate that are decomposing, we have 3 moles of oxygen gas produced.

So, we will set up our conversion factor like this:

0.0408163265 moles KClO3 *   3 moles Oxygen

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

                                                     2 moles KClO3

When we solve for this, we see that there are 0.0612244898 moles of O2 produced, or 0.0612 moles of O2 produced

Answer: 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide.

Explanation:

The balanced chemical reaction is;

[tex]Cl_2+MgBr_2\rightarrow MgCl_2+Br_2[/tex]

[tex]Cl_2[/tex] is the limiting reagent as it limits the formation of product and [tex]MgBr_2[/tex] is the excess reagent.

According to stoichiometry :

1 mole of [tex]Cl_2[/tex] produces = 1 mole of [tex]MgCl_2[/tex]

Thus 2 moles of [tex]Cl_2[/tex] will produce=[tex]\frac{1}{1}\times 2=2moles[/tex]  of [tex]MgCl_2[/tex]

 Mass of [tex]MgCl_2=moles\times {\text {Molar mass}}=2moles\times 95g/mol=190g[/tex]

Thus 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide

Explanation:

When a plate moves it shifts the earth, and it can cause an earthquake.

A fault is where two of earth's tectonic plates come together. They can slide against the other, causing earthquakes, they can push against each other causing mountains to form, and they can move apart from each other, causing  valleys or trenches.

Answer:

1. A

2. C

Explanation:

For the first question, we know that the water transformed into a gas. This fact eliminates choices C and D, primarily because they describe the change as "gas to liquid" instead of liquid to gas.

What separates B from A is that B is saying the liquid changed to a gas in response to sunlight, which is completely false and impertinent to the prompt.

A is the correct answer.

for the second question, we know that condensation causes clouds -- and that neither evaporation nor water vapor would clear clouds to make more of them, which eliminates choices B and D. Going back to condensation, the accumulation of water vapor plays a big role in the formation of clouds. While evaporation does play a part in [it] as well, condensation is what caused the sudden appearance of clouds in the troposphere.

C is the correct answer.

Explanation:

its because during day time the ball becomes heated up and the air inside it try to come out as the heat air always try to go up swelling up the ball,

so in the evening when the air cools down the ball too cools down and air inside it also cools down making the ball feel soft,

Therefore, a football feels hard on a hot day but feels softer in the evening​

Answer:

[tex]\boxed {\boxed {\sf D. \ Bronze}}[/tex]

Explanation:

Let's analyze the answer choices.

The first answer choices. diamond, coal, and graphite, all have something in common. They are allotropes of carbon. They are made of the same element, but each has a different arrangement of atoms, which leads to different properties.

Bronze is an alloy of copper, tin, and other metals. It's not an allotrope of carbon or related to the other answer choices. Therefore, it is the odd one out.

Answer:

The answer is A.

Explanation:

In periodic table, group 1 (1st column) are Alkali metals and group 2 (2nd column) are Alkali Earth metals.

A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. At the same concentration, weak acids have a higher pH value than strong acids.

Answer:

Genes on the X chromosome are said to be X-linked. X-linked genes have distinctive inheritance patterns because they are present in different numbers in females (XX) and males (XY). X-linked human genetic disorders are much more common in males than in females due to the X-linked inheritance pattern.
