The balanced chemical equation is:
2Fe+3H2O=Fe2O3+3H2
We are given the amount of water to be used in the reaction. This will be the starting point for the calculations.
3 mol H2O ( 1 mol Fe2O3 / 3 mol H2O ) = 1 mol Fe2O3
Therefore, the correct answer is option B.
Answer:
The Law of Conservation of Mass tells us that matter is neither created nor destroyed during a chemical reaction. ... The Law of Conservation of Mass applies as the total mass of the products is equal to the total mass of the reactants.

Answer:
<em>D) raises blood glucose levels. </em>
Explanation:
Glucagon is a small polypeptide synthesized by cells. This 29 amino acid peptide hormone is synthesized by pancreas alpha cells and has a molecular weight of 3485 dalton
It has an opposite effect to insulin by increasing blood glucose levels since it increases phosphorylase activity through cyclic AMP, after binding to glucagon receptors coupled to protein G on hepatocytes.
It is a stress hormone. Stimulates catabolic processes and inhibits anabolic processes.
The correct answer is D. raises blood glucose levels.

Answer:
1. Heating hydrogen gas from 60°C to 80°C: Entropy increases
2. Subliming dry ice: Entropy increases
3. Forming sucrose crystals from a supersaturated solution: Entropy decreases
4. Condensing water: Entropy decreases
Explanation:
Entropy is a measure of systems disorder. The higher the entropy the higher the disorder. So for the firs example if we heat a gas, molecules move faster, disorder is higher. For second example we are making disordered gas from very ordered crystals also increase in disorder. For 3rd example we are obtaining crystals which brings order. And for the fourth example we make liquid from gas which is also more order.
