They serve as a host for parasites and other microscopic organisms and they get spread through travel or through sewer systems
Use the equation m1 * v1 = m2 * v2
Example: (2.75 L)(1.5 M) = (12.0 M)(v2) then solve for v2
You may have to solve for m2 as well just plug and chug
First, we need to find the
limiting reactant. <span>
149 g Al x 1 mole/27g Al = 5.52 mol Al
601 g Fe2O3 x 1 mole/159.6g Fe2O3 = 3.77 mol Fe2O3
<span>Al is the limiting reactant since 3.77 mol Fe2O3 would
require 3.77*2 = 7.54 mol Al but the given is less.
<span>mol Al2O3 = 5.52 mol Al * 1 mol Al2O3 / 2 mol Al
= 2.76 mol</span>
mass Al2O3 = 2.76 mol x 102g/1 mole AlO3 = 281.52 g Al2O3
will be formed. </span></span>
<span>
Since 3.77 mole of Fe2O3 is present, but 5.52 mole Al is the
limiting reactant, then only 5.52/2 mole Fe2O3 can be used. This leaves an
excess of:</span>
Fe2O3 excess = 3.77 – 5.52/2
= 1.01 <span>
<span>1.01 mole Fe2O3 x 103.8g/1 mole Fe2O3 = 104.84 g Fe2O3 </span></span>
Answer:
d. All of the answers are correct
Yes, it depends on how much food each dog ate, what brand they preferred and the size of each dog.
