I’m not sure but I think it is C
Answer A: CO2
Reason: carbon dioxides formula is CO and the number next to it is the molecules
For a first order reaction, the half life is inversely proportional to the rate constant.
The formula is
half life = ln(2)/k = 0.693/k
where k is the rate constant
t = 5.50 minutes
k = ln(2)/5.50 = 0.126 min^-1
Your rate constant is 0.126 min^-1.
Liquefied Natural Gas
Explanation:
Gases are usually liquefied in the downstream sector during crude processing. These natural gases are products of distillation of crude oil in fractionating columns. Some of them are also found in geological formations.
- To easily transport these gases, they are liquefied in vessels that carries them from one place to another.
- Liquefaction is the process of converting a gas or solid into a liquid form.
- Gases are usually compressed under very high pressure into vessels through which can make them easier to transport.
- Gases do not have a fixed volume and they typically assume the volume of any container they are taken into.
