Answer:
The individual substances in a mixture can be separated using different methods, depending on the type of mixture. These methods include filtration, evaporation, distillation and chromatography.
Explanation:
Answer:
It is buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.

Answer:</h3>
True, the reaction given is an example of a synthesis reaction
<h3>
Explanation:</h3>
- Synthesis reactions are reactions where two or more substances combine to form a single compound.
- The reaction 2NO(g) + O₂(g) → 2NO₂(g) is an example of a synthesis reaction.
Other types of chemical reactions may include;
- Decomposition reaction in which a compound is broken down into smaller compounds or individual elements.
- Replacement reaction where reactive elements replace other less reactive elements in their salts.
- Precipitation reactions in which soluble salts reacts to form a precipitate and a soluble salt as a result of exchange of anions and cations.
Answer:
25 coolers are need to be produce and sell in order to minimize the cost.
Explanation:
..[1]
Differentiating the given expression with respect to dx.
Putting ,
x = 25
Taking second derivative of expression [1]
(minima)
25 coolers are need to be produce and sell in order to minimize the cost.
V= 50. L n=45 mol T= 200°C = 473k P=?
CP)X 50.L)= (45 mol)(0.0821 light_kimol)(473k)
P = 30am or 4000 kPa
