I just did this question in class:))
Answer:
Methane(CH₄).
Explanation:
- Thomas Graham found that, at a constant temperature and pressure the rates of effusion of various gases are inversely proportional to the square root of their masses.
<em>∨ ∝ 1/√M.</em>
where, ∨ is the rate of diffusion of the gas.
M is the molar mass of the gas.
<em>∨₁/∨₂ = √(M₂/M₁)</em>
<em></em>
- The molar mass of different choices:
Carbon dioxide: 44.01 g/mol.
Water vapor
: 18.0 g/mol.
Ammonia (NH₃): 17.0 g/mol.
Methane(CH₄): 16.0 g.mol.
<em>Since, methane has the lowest molar mass. So, it will diffuse faster within a system.</em>

Answer:
Store the genetic instructions needed to specify traits.
The solution for the question is the following:
NaCO3(aq) + CaCl2 (aq) --> CaCO3 + Na2Cl(aq)
Na 2+(aq) + CO3 -2 (aq) +Ca+(aq) + 2Cl-(aq) ---> CaCO3 + Na 2+(aq) + 2Cl-(aq)
Ca2+ (aq) + CO3 2- (aq) → CaCO3 (s) would be the balanced net ionic equation.
