Answer:

decomposition

Balanced chemical equation:

2HgO → 2Hg + O₂

Explanation:

Chemical equation:

HgO → Hg + O₂

Balanced chemical equation:

2HgO → 2Hg + O₂

The given reaction shows the decomposition reaction. Mercury oxide decompose and produced its constituent elements mercury and oxygen.

The oxidation state of mercury is +2 while that of oxygen is -2.

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

General equation:

AB → A + B

Problem 1. (Temperature and thermal equilibrium) Temperature is an indicator of: a. Total energy of the molecules in the system

horrorfan [7]

Answer:

The average kinetic energy of the molecules in the system

Explanation:

According to the kinetic theory of matter, the particles of a system are in constant motion and collide steadily with one another as well as with the walls of the container.

The average kinetic energy of these molecules in motion is referred to as the temperature of the body. Hence, temperature is a measure of the average kinetic energy of the molecules of a body.

Methyl red is a common acid-base indicator. it has a ka equal to 6.3 × 10–6. its un-ionized form is red and its anionic form is

Maksim231197 [3]

Hello!

The pKa of an indicator tells us the pH where it changes color. The pKa of Methyl red is

$pKa=-log(Ka)=-log( 6,3*10^{-6} )=5,20$

So, at a pH=7,8, Methyl Red would be at a pH over its pKa, so it would be in its basic form. The Basic Form of Methyl Red is Yellow, so the solution would be Yellow.

Have a nice day!

Know how you would determine the percent yield of a reaction if you have the given amount of the reactants and the amount of the

Over [174]

First, use the given amount of reactants to calculate the theoretical amount of products that should be formed based on stoichiometry. Next, divide the actual amount of obtained product by that theoretical amount, and multiply by 100%. This gives the percent yield of the reaction.
