It is each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
Answer:
the left side are the reactants and the right side is the products
Explanation:
The reactants are the elemental compounds that are being turned into the product
4.305 L = 4.305 × 10^6 µL
1 µL = 10^(-6) L
∴ 4.305 L × [1 µL/10^(-6) L] = 4.305 × 10^6 µL
The time taken for the same volume of methane gas to diffuse is 7.1 s.
<h3>
Rate of gas diffusion</h3>
The rate at which a given mass of diffuses is inversely proportional to the molar mass of the gas.
where;
- M1 is the molar mass of methane (CH4) = 16 g
- M2 is the molar mass of hydrogen as = 2
- t1 is time taken for methane = 20 s
- t2 is the time taken for hydrogen = ?
Thus, the time taken for the same volume of methane gas to diffuse is 7.1 s.
