<u>Answer:</u> The chemical species formed in a chemical reaction are products.

<u>Explanation:</u>

In a chemical equation, the chemical species are called as reactants or products.

Reactants are defined as the chemical species that react in the reaction and are written on the left side of the reaction arrow.

Products are defined as the chemical species that are produced in the reaction and are written on the right side of the reaction arrow.

<u>For Example:</u>  Formation of water from hydrogen and oxygen gases, the equation follows:

2H_2(g)+O_2(g)\rightarrow 2H_2O(l)

The chemical species H_2\text{ and }O_2 are termed as reactants and H_2O is termed as products.

Hence, the chemical species formed in a chemical reaction are products.

Helium gas diffuses 4 times as fast as an unknown gas. What is relative molecular mass of the gas​
Inessa05 [86]

The relative molecular mass of the gas​ : 64 g/mol

<h3>Further explanation</h3>

Given

Helium rate = 4x an unknown gas

Required

The relative molecular mass of the gas​

Solution

Graham's Law

\tt \dfrac{r_1}{r_2}=\sqrt{\dfrac{M_2}{M_1} }

r₁=4 x r₂

r₁ = Helium rate

r₂ = unknown gas rate

M₁= relative molecular mass of Helium = 4 g/mol

M₂ = relative molecular mass of the gas​

Input the value :

\tt \dfrac{4r_2}{r_2}=\sqrt{\dfrac{M_2}{4} }\\\\16=\dfrac{M_2}{4}\\\\M_2=64~g/mol

What is the molar mass of an element?
Vesnalui [34]

The answer is: the mass of 6.02 x 1023 representative particles of the element.

The base SI unit for molar mass is kg/mol, but chemist more use g/mol (gram per mole).

For example, molar mas of ammonia is 17.031 g/mol.

M(NH₃) = Ar(N) + 3 · Ar(H) · g/mol.

M(NH₃) = 14.007 + 3 · 1.008 · g/mol.

M(NH₃) = 17.031 g/mol.

The molar mass (M) is the mass of a given substance (in this example ammonia) divided by the amount of substance.
