Answer: (2)react completely in the reaction
limiting reactant determines the number of moles in a chemical reaction
excess reactant is the reactant with an excess number of moles
D. Simplification incorrect answer
Answer:
<h2>2200 L</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 37.4 g
density = 0.017 g/L
We have
We have the final answer as
<h3>2200 L</h3>
Hope this helps you
Answer:
B) ΔT = Q/mCp
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.Cp. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
Cp = specific heat capacity of substance
ΔT = change in temperature
ΔT = Final temperature - initial temperature
The substances with higher value of specific heat capacity require more heat to raise the temperature by one degree as compared the substances having low value of specific heat capacity.For example,
The specific heat capacity of oil is 1.57 j/g. K and for water is 4.18 j/g.K. So, water take a time to increase its temperature by one degree by absorbing more heat while oil will heat up faster by absorbing less amount of heat.
