I believe the answer is d summarizing
Answer:
5010J
Explanation:
The following data were obtained from the question:
Mass (m) = 15g
Heat of fusion (ΔHf) = 334J/g
Heat required (Q) =..?
The heat energy required to melt the ice can be obtained as follow:
Q = m·ΔHf
Q = 15 x 334
Q = 5010J
Therefore, the heat energy required to melt the ice is 5010J.
Answer:
There are a total of 8 electrons around the carbon, in 4 pairs. Because there are 4 bonds, these are all bond pairs. Each double bond uses 2 bond pairs - which are then thought of as a single unit.
