Because it’s more energy efficient
This question uses mole ratios. firstly, we look at how many moles of H2 are produced for every mole of HCl: from 1 Hcl, we get half a mole of H2. therefore, however many moles of HCl are present in the 0.075 L of 1.0M HCl, half that number of H2 moles will be produced.
n=cv
=0.0750 x 1.0
=0.075 mol HCl
n(H2)= 0.5 x n(HCl)
=0.0375 moles of H2
This would support Dalton's postulates that says atoms are indivisible because there are no smaller particles than the atoms.
Explanation:
If during Thomson's cathode rays experiment, the size of the particles produced is the same as the size of the atom forming the cathode, it would perfect corroborate with Dalton's postulate.
- John Dalton believed the simplest substance of any matter is an atom.
- An atom is indivisible and cannot be broken down.
- From his atomic theory, matter does not any other smaller particles besides atom.
- If the size of the atoms of rays and that of the cathode were to be the same, this would have supported his claim.

Answer:
The equation showing the dissolving of solid ammonium phosphate in water is: (NH4)3 PO4 (s) → 3NH4 +1 (aq) + PO4 -3 (aq).
Explanation:
<u>Answer:</u> The equation is written below.
<u>Explanation:</u>
For the formation of nitrogen dioxide, the reactants used are nitrogen monoxide and oxygen gas.
The balanced chemical equation for the above reaction is given as:
By Stoichiometry of the reaction:
2 moles of nitrogen monoxide gas reacts with 1 mole of oxygen gas to produce 2 moles of nitrogen dioxide gas.
