Answer: (C) Dissolution is the process by which a solute form a solution in a solvent.
Explanation: Dissolution can be described as the process by which a solute dissolves in a solvent to give a solvent.
The solute may be a solid, liquid or gas and solvent is usually a liquid but can also be liquid, gas or supercritical fluid. The most common solvent is water and it is referred to as the universal solvent.
Example are:
1.Stirring of sugar in water.
In this case the solute is the sugar and the solvent is water.
2.Organic substances dissolves readily in solvent like kerosene and benzene and they are known as non-polar solvent while the organic substances are the solute
The mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.
The given parameters:
- <em>Density of the octane, ρ = 0.703 g/ml</em>
- <em>Volume of octane, v = 3.79 liters</em>
<em />
The mass of the octane burnt is calculated as follows;
![m = \rho V\\\\m = 0.703 \ \frac{g}{ml} \times 3.79 \ L \ \frac{1000 \ ml}{L} \\\\m = 2,664.37 \ g](https://tex.z-dn.net/?f=m%20%3D%20%5Crho%20V%5C%5C%5C%5Cm%20%3D%200.703%20%5C%20%5Cfrac%7Bg%7D%7Bml%7D%20%5Ctimes%203.79%20%5C%20L%20%5C%20%5Cfrac%7B1000%20%5C%20ml%7D%7BL%7D%20%5C%5C%5C%5Cm%20%3D%202%2C664.37%20%5C%20g)
The combustion reaction of octane is given as;
![2C_8H_{18} + \ 25O_2 \ --> \ 16CO_2 \ + \ 18H_2O](https://tex.z-dn.net/?f=2C_8H_%7B18%7D%20%2B%20%20%5C%2025O_2%20%5C%20--%3E%20%5C%2016CO_2%20%5C%20%2B%20%5C%2018H_2O)
From the reaction above:
228.46 g of octane -------------------> 704 g of CO₂ gas
2,664.37 of octane --------------------> ? of CO₂ gas
![= \frac{2,664.37 \times 704}{228.46} \\\\= 8,210.3 \ g\\\\= 8.21 \ kg](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B2%2C664.37%20%5Ctimes%20704%7D%7B228.46%7D%20%5C%5C%5C%5C%3D%208%2C210.3%20%5C%20g%5C%5C%5C%5C%3D%208.21%20%5C%20kg)
Thus, the mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.

Answer:
Law of Lateral Continuity The Grand Canyon.
and
he same rock layers on opposite sides of the canyon. The matching rock layers were deposited at the same time, so they are the same age.
Well you are at a 86% so t<span>his is considered a "B" grade on an average grade scale. If you take 50 points we would need to know the Total point you could have got in that class to be able to see how much a percent was the assignment work and then take that percentage of the assignment and subtract it from the 86% to see where on the scale you would fall in after the assignment points were taken off. Hope this helps :)
