Alpha particle has a mass of 4 (Two protons and two neutrons)
Neutron has a mass of 1
Beta particle has a mass of about 0 (Electron)
Proton has a mass of 1
So the answer is (2) Beta particle
Answer:
335.35 grams
Explanation:
Convert grams of H2SO4 to moles and get 4.08 moles.
Using stoichiometry, the chemical equation tells us that for every mole of H2SO4, one mole of Na2SO4 is produced. This means that, theoretically, you should get 4.08 moles.
Convert moles to grams and get 335.34 g.
However, if you were to actually perform this reaction, you would get less than the theoretical value.
Hope this helps! <3
The reaction is
<span>Zn (s) + 2 HCl (aq) ----> ZnCl2 (aq) + H2 (g)
which is already balanced
5.4 L of 2.8 M HCl contains
5.4 L (2.8 M) = 15.12 moles HCl
The amount of Zinc that will react completely with the acid is
15.12 mol HCl (1 mol Zn / 2 mol HCl) (65 g Zn/1 mol Zn) = 491.4 g Zn
