O2(g) effuses at a rate that is times that of br2(g) under the same conditions.

Oxygen gas effuses at a rate that is 2.236 times that of bromine gas under the same conditions.

Explanation:

Graham's Law:

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

We are given:

Molar mass of oxygen gas= 32 g/mol

Molar mass of bromine gas = 160 g/mol

By taking their ratio, we get:

Oxygen gas effuses at a rate that is 2.236 times that of bromine gas under the same conditions.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
