A student observes the chemical process described by this equation:
choli [55]

Answer:

Both are equal

Explanation:

Mass of starting material i.e Aluminium is 4.480 * 10^{-23} grams

The weight of oxygen is 2.65 * 10^{-23}

There are 4 atoms of aluminium and 3 atoms of oxygen

Thus, the total mass of starting material is

4 * mass of one atom of aluminium + 6 * mass of one atom of oxygen

4 * 4.480 * 10^{-23} +  6* 2.65 * 10^{-23}

35.1 * 10^{-23} grams

Mass of new substance is also equal to

4 * mass of one atom of aluminium + 6 * mass of one atom of oxygen

4 * 4.480 * 10^{-23} +  6* 2.65 * 10^{-23}

35.1 * 10^{-23} grams

If you weighed out 0.38 g of calcium and reacted it with an excess of hcl, how many moles of h2(g) would you expect to produce?
Hitman42 [59]
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.
