The higher the frequency of a wave, the SHORTER the wavelength of the wave.
percentage of zinc= 5.985/20 X 100= 29.5%
let x represents zinc and y be magnesium so
Zinc(s) + 2HCl(aq) -----> ZnCl2(aq) + H2(g)
Mg(s) + 2HCl(aq) -----> MgCl2(aq) + H2(g)
1.152 g of hydrogen gas=( x/65.3 + y/24.305) 20
= 3.08 x10^-2 + 0.8295-8.30
=x=5.985
y= 4.015
percentage of zinc= 5.985/20 X 100= 29.5%
The hydrogen gas escapes, so the two products of Zinc Chloride and Magnesium Chloride will then react with Silver Nitrate. Again, I combine both of the reactions
