Answer:
The answer is
<h2>8.4 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 88.2 g
density = 10.5 g/cm³
The volume is
We have the final answer as
<h3>8.4 mL</h3>

Answer:
C. Double Replacement
Explanation:
A. Wrong because SR uses a compound and element. This equation is a compound and compound.
B. Wrong because it does not have O2 in the formula. All combustion reactions must have O2.
C. Correct because it is a compound reacting with a compound.
D. Wrong because the reactants did not form a single product. ex. (x + y > xy)
E. Wrong because the equation did not start with a single compound and break down. ex. (xy > x + y)
Answer is "sucrose".
Polymer is a large molecule which is made from repeating units. The smallest repeating unit is called as monomer. <span>Polystyrene, nylon and PVC are examples for polymers. But sucrose is a disaccharide which is made from glucose and fructose. Hence, sucrose is not an example of polymer. </span>
In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
