Use the following image to answer the following questions. A student was performing an experiment using two identical cups made
of styrofoam. The student had Cup A holding water at 90℃ and Cup B holding water at 20℃. The student then put an Aluminum Bar into each cup that was touching the water. As time passed, the student noticed that the temperature of the water in Cup A and Cup B began to change. Question:
A. Predict what will happen to the temperature of the water in Cup A and Cup B after 1 hour has passed.
B. Explain and give evidence for what type of heat transfer is occurring between the 2 cups.
Whoever answers my question gets brainliest

Answer:
Plausible structure has been given below
Explanation:
- Molar mass of
is 44 g/mol and molar mass of
is 18 g/mol
- Number of mole = (mass/molar mass)
4.04 g of =
= 0.0918 moles of
1 mol of contains 1 mol of C atom
So, 0.0918 moles of contains 0.0918 moles of C atom
1.24 g of =
= 0.0689 moles of
1 mol of contain 2 moles of H atom
So, 0.0689 moles of contain
of
or 0.138 moles of
Moles of C : moles of H = 0.0918 : 0.138 = 2 : 3
Empirical formula of hydrocarbon is
So, molecular formula of one of it's analog is
Plausible structure of has been given below.
