(A) is the answer
Explanation:
(A) heat a saturated sugar water solution, dissolve more sugar, then let the solution cool
The moles of hydrogen required for the synthesis of 13.78 mol ethane has been 27.56 mol. Thus, option C is correct.
The balanced chemical equation for the synthesis of ethane has been:
In a balanced chemical equation for the synthesis of 1 mole of ethane, 2 moles of hydrogen is required.
The moles of hydrogen required for the synthesis of 13.78 mol of ethane has been:
The moles of hydrogen required for the synthesis of 13.78 mol ethane has been 27.56 mol. Thus, option C is correct.

Answer:
2. CH4
5. C2H 6
Explanation:
there are only two organic compounds there.
hope it helps .
Start by looking to the product there that doesn't have coefficient. Need to have exactly 2 Fe on the reactant side. So first coefficient is 2.. having a 2 there gives 2*3 = 6 H on the reactant side. Then in order to have 6 H on the product side the coefficient there needs to be 3. This gives 3 Ca on product side so there must be 3 Ca on reactant side.
coefficients:
2 + 3 --> 1 + 3
Answer:
okay introduction
-what is gravity
-it's effects
detail one
-what is the advantages
-the disadvantages
detail two
-how gravity work
-what would happen if there was no gravity
okay this is all I could think of
