To make salt water a heterogeneous mixture, you would have toA) add sand.
B) add a small amount of sugar.
C) boil the water.
D) remove the salt.
Answers
because sand is insoluble, it will make the solution heterogeneous
Answer:
A. Add sand
Explanation:
A mixture in which particles are not uniformly distributed throughout the solution then it is known as a heterogeneous mixture.For example, sand in water is a heterogeneous mixture.Where as a mixture in which particles are evenly distributed throughout the solution then it is known as a homogeneous solution.For example, salt in water is a homogeneous solution. This, is why we can conclude that to make salt water a heterogeneous mixture, you would have to add sand.
Hopefully this answers your question.

What is gas ?
One of the four basic states of matter, along with solid, liquid, and plasma, is gas. Individual atoms, elemental molecules derived from a single type of atom, or complex molecules derived from a number of atoms can all be found in a pure gas. A variety of pure gases can be found in a gas mixture like air.
If temperature and pressure remain constant, doubling the moles of a gas results in a doubling of its volume. An inflated tire takes up more room than a flat tire. Lungs enlarge as air is absorbed into them. Lung volume reduces when you exhale.
You will investigate four parameters that quantify gases in this activity: pressure (P), volume (V), temperature (T), and moles (n) of gas.
Thus, Four commonplace items that depend on gas behavior to function effectively.

Petrol is separated from the hydrocarbons in crude oil via fractional distillation, a process that uses the different boiling points of hydrocarbons to separate them. Lighter hydrocarbons like petrol vaporize at lower temperatures and are then condensed and collected separately.
different fractions, including petrol from the crude oil.
Explanation:
Petrol is separated from a mixture of hydrocarbons in crude oil through a process known as fractional distillation. This process takes advantage of the different boiling points of hydrocarbons present in crude oil. The crude oil is heated, and as the temperature increases, different hydrocarbons begin to vaporize.
For example, petrol, which is composed of relatively light hydrocarbons, will vaporize at lower temperatures compared to heavier hydrocarbons like diesel or lubricating oil. After being vaporized, the hydrocarbons are condensed and collected separately, effectively separating the

1L = 4.2 cups
4 L = [?] cups
Answers
Answer:
16.8 cups
Explanation:
We are given that there are 4.2 cups in in 1 liter of a liquid and we are to find out the number of cups that there will be in 4 liters.
To find this out, we will use the ratio method.
We know that:
1 L = 4.2 cups
So we can write it as:
Therefore, there are 16.8 cups in 4 liters.
16.8 cups are in 4 liters. A conversion factor is a ratio that allows you to convert a quantity expressed in one unit to an equivalent quantity expressed in another unit.
It is used in various fields, such as physics, chemistry, engineering, and everyday measurements. Conversion factors are derived from the relationships between different units of measurement.
1 liter is equivalent to 4.2 cups. This conversion factor tells that for every 1 liter, we have 4.2 cups.
To find out how many cups are in 4 liters, multiply 4 liters by the conversion factor of 4.2 cups per liter:
4 liters x 4.2 cups/liter = 16.8 cups
So, 4 liters would have 16.8 cups. This means that if 4 liters of liquid are into cups, need 16.8 cups to hold it all.

P = 1.25 atm
V = 5.4 L
P1 = 3 atm
V1 = ??
Formula
The basic formula is P*V = P1 * V1
Solution
1.25 * 5.4 = 3 * V1
6.75 = 3*V1
6.75 /3 = 3*V1/3
2.25 = V1
