<span>Yes that answer is correct. John dalton was an english scientist who lived during the 18th and 19th centuries and he is most famous for proposing the modern first widely recognized atomic theory.

Wax will be dissolved by nonpolar solvents: (a) hexane, (b) benzene and (d) carbon tetrachloride
Wax will not be dissolved by polar solvent such as (c) acetone and (e) water
Add the weight of chromium, nickel and iron to get 25 pounds. Then divide the weight of chromium by the weight of the stainless steel to get 18%. Then find 18% of 25 g which is 4.5 g.
Answer is: 0,0095 mol of hydrogen gas will be produced in reaction.
Chemical reaction: Ca + 2HCl → CaCl₂ + H₂.
m(Ca) = 0,38 g.
n(H₂) = ?
n(Ca) = m(Ca) ÷ M(Ca).
n(Ca) = 0,38 g ÷ 40 g/mol
n(Ca) = 0,0095 mol.
from reaction: n(Ca) : n(H₂) = 1 : 1.
n(H₂) = n(Ca) = 0,0095 mol.
n - amount of substance.
