I believe it is kinetic energy
Hope this is right .-.
"a quantity representing the amount of water vapor in the atmosphere or a gas."
Answer:
0.726 mol·L⁻¹
Step-by-step explanation:
c = moles/litres
=====
Moles = 29.8 × 1/342.30
Moles = 0.087 06 mol
=====
Litres = 120 × 1/1000
Litres = 0.120 L
=====
c = 0.087 06/0.120
c = 0.725 mol·L⁻¹
Single Replacement

Given
Reaction
Mg(s) + 2 HCl(aq) → MgCl2 (aq) + H2 (g)
Required
Type of reaction
Solution
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
General formula :
A + BC ⇒ AC + B
Not all of these reactions can occur. We can use the activity series(the Volta series)
The more left the position of a metal in the series, the more reactive metal (easy to release electrons, the stronger the reductor)
