Answer:
Most substances on earth are compounds and most interesting chemistry is done with compounds. Most interesting chemistry is done with mixtures of compounds although they often start with pure compounds and then do reactions as mixtures. Most chemistry is carried out in liquid solutions made up of compounds that are solids, liquids, or gases in their pure form.
Explanation:
Based on the information given regarding the energy, the true statement is C. "The number of particles able to undergo a chemical reaction is less than the number that is not able to."
<h3>What is energy?</h3>
It should be noted that energy is the quantitative property that must be transferred to a body to perform work on the body.
In this case, the graph is shown with two inverted graph curves running close to each other, and one of the curves labeled T1 is slightly more spread out than the other labeled T2.
Here, T1 is the only sample with a particle able to react. Particle B is more likely to participate in the reaction than particle A and the number of particles able to undergo a chemical reaction is less than the number that is not able to.

Answer:
Homogénea
Explanation:
Una mezcla homogénea ocurre cuando se unen dos o más sustancias y no se pueden identificar después de ser unidas
En este caso no se logran identificar los compuestos
Answer:
2HgO → 2Hg + O₂
The reaction is a decomposition reaction because from one reactant two products were obtained
Explanation:
The problem here involves balancing the chemical reaction given and also classifying the reaction.
The unbalanced expression is given as:
HgO → Hg + O₂
Assign the alphabets a,b and c as coefficients that will balance the equation
aHgO → bHg + cO₂
Conserving Hg: a = b
O: a = 2c
So, let c = 1, a = 2 b = 2
Therefore;
2HgO → 2Hg + O₂
The reaction is a decomposition reaction because from one reactant two products were obtained
