What mass of gallium oxide Ga2O3 can be prepared from 29 g of gallium metal? The equation for the reaction is \(4Ga + 3{O_2} \to 2G{a_2}{O_3}\)

Short Answer

Expert verified

39g of Gallium oxide can be prepared from 29 g of gallium metal.

Step by step solution

01

Calculating the number of moles of gallium oxide

Number of moles in 29 g of gallium metal

\(\begin{array}{l} = \frac{{29}}{{70\left( {rounding\,off\,69.7} \right)}}\\ = 0.414\,mol\end{array}\)

From the balanced reaction, we can say that 2 moles of gallium will produce 1 mole of gallium oxide, So, 0.414 moles of gallium will produce 0.207 mol of gallium oxide.

02

Calculating the mass of gallium oxide

Using the formula of moles, we get

Moles = mass/molecular mass

\(\begin{array}{c}0.207 = \frac{x}{{187.4}}\\x = 38.7\end{array}\)

Therefore, 39g of Gallium oxide can be prepared.

The principal component of mothballs is naphthalene, a compound with a molecular mass of about 130 amu, containing only carbon and hydrogen. A 3.000-mg sample of naphthalene burns to give 10.3 mg of CO2. Determine its empirical and molecular formulas.

A novel process for obtaining magnesium from sea water involves several reactions. Write a balanced chemical equation for each step of the process.

(a)The first step is the decomposition of solid calcium carbonate from seashells to form solid calcium oxide and gaseous carbon dioxide.

(b)The second step is the formation of solid calcium hydroxide as the only product from the reaction of the solid calcium oxide with liquid water.

(c)Solid calcium hydroxide is the added to the sea water, reacting with dissolved magnesium chloride to yield solid magnesium hydroxide and aqueous calcium chloride

(d)The solid magnesium hydroxide is added to a hydrochloric acid solution, producing dissolved magnesium chloride and liquid water.

(e)Finally, the magnesium chloride is melted and electrolyzed to yield liquid magnesium metal and diatomic chlorine gas.
