Answer:
d. Heat is released from the reaction
Explanation:
A negative enthalpy change indicates that it is an exothermic reaction. Exothermic reactions release heat.
In short, I’d say the answer is C.
In solids, the intermolecular force of attraction is very high. Whereas, in liquids the intermolecular force of attraction is somewhat less than solids. ... so when you heat, less amount of heat can free the molecules in liquids than solids and hence they heat faster.
Answer:
Explanation:
Hello,
In this case, since one drop equals 0.05 mL of the given solution, for a concentration 0.02 g/mL, the grams of oleic acid in one drop turns turn out:
Best regards.
Answer:
<h3>The answer is 8.40 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
volume = final volume of water - initial volume of water
volume = 56.4 - 50 = 6.4 mL
We have
We have the final answer as
<h3>8.40 g/mL</h3>
Hope this helps you
