Answer:
220.9g of water are required
Explanation:
The molar enthalpy of vaporization is defined as the heat released when 1 mole of water changes from liquid to gas.
For water, 1 mole releases 40.79kJ. To release 500kJ are necessaries:
500kJ * (1mol / 40.79kJ) = 12.26 moles are necessaries
To convert moles to grams we must use the molar mass (H2O = 18.02g/mol):
12.26 moles * (18.02g / 1 mol) =
<h3>220.9g of water are required</h3>
Answer:
3.193 mol
Explanation:
The reaction is

We use the stoichiometry in order to find the moles of nitrogen required.


The amount of nitrogen required is 3.193 mol to produce 9.58 mol of ammonia.

Answer:
In 1911, Rutherford showed that Thomson's model was "wrong": the distribution of positive and negative particles was not uniform. Rutherford showed that the atom contains a small, massive, positively charged nucleus. He also agreed with Nagaoka that the electrons move in circular orbits outside the nucleus
