Answer: 
Explanation:
You need to know the conversion factor first in order to solve this. Any gas occupies 22.4L per mol.
of nitrogen gas.
Acids will typically start with a Hydrogen, so HI and HNO₃ are most likely
Hydrocarbons that lack π bond are called saturated hydrocarbons or alkanes
<h3>Hydrocarbons</h3>
- Hydrocarbon is an organic compound consisting of hydrogen and carbon.
- Hydrocarbons is an examples of 14 group hydrides.
- Hydrocarbons are colorless and hydrophobic.
- Their odors are usually like gasoline or lighter fluid.
- In oil and gas industry, the hydrocarbon in term, combines petroleum and natural gas they are the two naturally occurring phases of hydrocarbon.
<h3>Alkanes</h3>
- Alkanes also konwn as parafins
- They are called as saturated hydrocarbons
- Alkanes contain hydrogen and carbons arranged in tree structure
- Alkanes have two main sources petroleum and natural gas.
Therefore, Hydrocarbons that lack π bond are called saturated hydrocarbons

Explanation:
The pH of a substance can be found by using the formula
![pH = - log[ H^{ + } ]](https://tex.z-dn.net/?f=pH%20%3D%20%20-%20%20log%5B%20H%5E%7B%20%2B%20%7D%20%20%5D)
where [ H+ ] is the hydrogen ion concentration in the substance
From the question
[ H+ ] = 2.1 × 10-¹² M
To find the pH substitute the value into the above formula
We have
We have the answer as
<h2>pH = 11.7 </h2>
The solution is basic since it lies in the basic region that is from 8 to 14

Answer:
Place the reactants in a smaller container.
Explanation:
If you were to reduce the source of heat, the hydrogen and oxygen molecules would lose their kinetic energy, resulting in less collisions.
_______________________________________________________
Maintaining the same temperature of the reactants, the speed would neither increase nor decrease as temperature is directly proportional to the kinetic energy of the molecules, which in turn is directly proportional to the number of collisions. However, placing the reactants in a smaller container would result in less volume, and hence the molecules would collide with one another more often!
