Which statement describes a chemical reaction?

ELEN [110]

The statement that describes a chemical reaction is the statement c. reactants form products when atoms are rearranged.<span> The atoms of the reactants are arranged is a specific position and number forming a determined compound. In a chemical reaction, the products are different compounds than the reactants, so the atoms have to rearrange to form these new compounds (the products).</span><span />

A 1. 00 ml sample of an unknown gas effuses in 11. 1 min. an equal volume of h2 in the same apparatus under the same conditions

Damm [24]

A 1. 00 ml sample of an unknown gas effuses in 11. 1 min. an equal volume of h2 in the same apparatus under the same conditions effuses in 2. 42 minutes then the molar mass of the unknown gas is 41.9.

Molar mass of H2 = 2

Molar mass of unknown gas = ?

rate 1 = 11.1

rate 2 = 2.42

<h3>What is graham law? </h3>

Graham's law states that the rate of diffusion or effusion of a given gas is inversely proportional to the square root of its molar mass.

By apply graham law

Rate1/rate2 = sqrt(MW2/MW1)

$[\frac{rate1}{rate2} ]^{2} = \frac{MW2}{2} \\\\\\mw= 2[\frac{11.1}{2.42} ]^{2} \\\\= 20.97 X 2 \\\\= 41.9$

Thus, we found that the molar mass of the unknown gas is 41.9.

The atomic nucleus contains?

ycow [4]

The nucleus, that dense central core of the atom, contains both protons and neutrons. Electrons are outside the nucleus in energy levels. Protons have a positive charge,neutrons have no charge, and electrons have a negative charge. A neutral atom contains equal numbers of protons and electrons.
