Answer: 0.050 moles of nitrogen monoxide are produced by 0.050 moles of ammonia.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reaction is:
According to stoichiometry:
4 moles of ammonia produce = 4 moles of nitrogen monoxide
Thus 0.050 moles of ammonia produce =
moles of nitrogen monoxide
Answer:
Boiling point.
Explanation:
Flammability, reactivity and toxicity are all chemical properties!
Technetium, with atomic number denoted Z43, is the lowest-numbered element in the periodic table of which all isotopes are radioactive
Answer:
2.4x10² kcal
Explanation:
As the serving of fish contains 50g of protein that is 4.0kcal/g:
50g × (4.0kcal/g) = <em>200kcal</em>
<em> </em>
And in 4g of fat that is 9.1kcal/g:
4g × (9.1kcal/g) = <em>36.4kcal</em>
<em />
That means the kcal of the serving are:
200kcal + 36.4kcal = 236.4kcal
In 2 significant figures: <em>2.4x10² kcal</em>
<em></em>

It would be. 2Fe + 3O2 ——> 2Fe03. You have to make oxygen 6 on both sides in order to balance, then you can do Fe. Which on the right would be 2 by making oxygen 6. Then add the 2 to the other side to balance it.
