Answer:

Explanation:
Hello,
In this case, the undergoing chemical reaction is:

Next, we identify the limiting reactant by computing the available moles of ethane and the moles of ethane consumed by 60.0 grams of oxygen:

Thus, we notice there are less available moles, for that reason, the ethane is the limiting reactant. Finally, we can compute the produced moles of water by:

Best regards.
I think its 2-, it gained 2 electrons.
Answer:
2 M
Explanation:
mole weight of CaBr2 = 40 + 2 * 79.9 = 199.8 gm
20 gm is then 20/199.8 =.1 mole
.1 mole / .50 liter = 2 M
I don’t know but I think it would be products... that’s the best I can give. I’ll look more into it
Answer: Disaccharides
Explanation:
Disaccharides can be defined as the combination of two monosaccharides which combines together to form a disaccharides.
These are formed by the combination of sugars. The process is hydrolysis as it releases water after the reaction is complete.
Two monosachrrides are joined together by the glycosidic linkage. Some common examples are maltose, sucrose and lactose.
