The process which has taken place is called CRYSTALLIZATION.
Generally, crystallization is the process by which solid crystals are precipitated from solution. Crystallization can also occur when a crystal melt or when a crystal get deposited directly from a gas, although these cases are rarer compare to crystals forming from solutions.
Answer:
2.58g
Explanation:
First calculate the moles of butane used in the reaction
moles = mass÷molar mass
= 0.85÷58
= 0.0147
According to the stoichiometric ratio:
C4H10 : CO2 = 2:8
moles of CO2 =(8÷2)×0.0147
=0.0586 moles
mass of CO2 = 0.0586×44
= 2.58g
Answer:- The correct answer is B. measuring the height of a building.
Explanations:- Insects and ants are very small. So, meter is not the right unit of measure their length. Their lengths would be measure in mm that is millimeters. So, options A and C are not good.
The distance between two cities is mostly too much so it's measured in kilometers or miles. So, D is also not good.
Height of buildings is measured in meters and so the correct option is B.
I’m not sure but I’m sure it’s b please thank me
