They are changes in bonding energy between the molecules. ... Immediately after the molecular bonds in the ice are broken the molecules are moving (vibrating) at the same average speed as before, so their average kinetic energy remains the same, and, thus, their Kelvin temperature remains the same."
Answer:
20 mol H₂
General Formulas and Concepts:
<u>Chem</u>
Explanation:
<u>Step 1: Define</u>
RxN: C + H₂ → CH₄
8 moles CH₄
<u>Step 2: Balance RxN</u>
C + 2H₂ → CH₄
<u />
<u>Step 3: Stoichiometry</u>
= 16 mol H₂
<u>Step 4: Check</u>
<em>We are given 1 sig fig. Follow sig fig rules.</em>
16 mol H₂ ≈ 20 mol H₂
The group 17 elements of the periodic table have 7 valence electrons and are highly reactive, with low melting and boiling points. The halogens - including fluorine, chlorine and bromine - have a common tendency to form salts, but they are all of a toxic nature.

Molarity is defined as the moles of solute per liter of solution. 
. Where M is molarity, n is the number of moles and V is the volume. First we must find the molar mass of 
which is 109.98 g/mol
Then we find the molarity using above equation
