The answer is C. Two Nonmetals
Answer:
3 mol H2 / 1 mol NH3
Explanation:
Mole ratio depicts or shows the relationship between the number of moles of two substances in a chemical reaction. The following chemical equation is given:
N2 + 3H2 → 2NH3
According to the above chemical equation;
- 1 mole of N2 reacts
- 3 moles of H2 reacts
- 2 moles of NH3 is produced
Hence, this means that according to the options provided in this question, the incorrect one is 3 mol H2 / 1 mol NH3 because 2 moles rather than 1 mol of NH3 is involved.
1 mol = 6.022 x 10²³ atoms
In order to find how many atoms, dimly multiply the amount of moles you have by 6.022 x 10²³ or Avogadro's number.
So you have 1.75 mol CHC1₃ x (6.022x10²³) = 1.05385 x 10²⁴ atoms of CHCl₃
But now you have to round because of the rules of significant figures so you get 1.05 x 10²⁴ atoms of CHCl₃
Answer:
The water is universal solvent because it is a polar molecule.This have hydrogen bonding in which hydrogen molecule have positive charge and oxygen molecule have negative charge because electro negativity of oxygen molecule is higher than hydrogen molecule that is why it pull the hydrogen molecule and formed a polar molecule.That is why is also known as universal solvent.
