A solution with a molarity of 7.65 mol/L and a volume of solution of 0.690 L, contains 5.28 moles of solute.
<h3>What is molarity?</h3>
Molarity is the number of moles of solute per liter of solution.
A solution has a molarity (M) of 7.65 mol/L and a volume (V) of 0.690 L. We can calculate the number of moles of solute (n) using the following expression.
M = n / V
n = M × V = 7.65 mol/L × 0.690 L = 5.28 mol
A solution with a molarity of 7.65 mol/L and a volume of solution of 0.690 L, contains 5.28 moles of solute.

Answer:
Surface waves travel along the surface. There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids.

In general terms, exothermic reactions release energy, so the energy goes from the system to the surroundings.
Answer: Theoretical yield is 313.6 g and the percent yield is, 91.8%
Explanation:
To calculate the moles :


According to stoichiometry :
1 mole of
require 3 moles of 
Thus 2.8 moles of
will require=
of 
Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 1 mole of
give = 2 moles of 
Thus 2.8 moles of
give =
of 
Mass of 
Theoretical yield of liquid iron = 313.6 g
Experimental yield = 288 g
Now we have to calculate the percent yield

Therefore, the percent yield is, 91.8%
Answer:As temperature increases, reactions take place. Generally, higher temperatures mean faster reaction rates; as molecules move about more quickly, reactant molecules are more likely to interact, forming products.
