In the combined gas law, if the volume is decreased, what happens to the temperature if pressure remains constant?a. The temperature decreases.
b. The temperature increases.
c. The temperature remains the same.

Answers

Answer 1

Answer:

The correct answer is A. In the combined gas law, if the volume is decreased and the pressure is constant, then the temperature decreases.

P1V1/ T1 = P2V2 / T2

Assume the volume decrease by half; V2 = V1/2

P1V1/ T1 = P2V1 /2 T2

Cancelling terms,

1/T1 = 1/2 T2

T2 = T1/2

Thus, the temperature decreased.

Explain, in terms of both atoms and molecular structure, why there is no isomer of CH3OH.

There is no isomer of CH3OH or methanol because it contains only one carbon atom. And also, the structure is tetrahedral, having four substances attached to the carbon atom.

Answers

The observed trait of the individual rabbitis referred to as the phenotype.

Organisms receive a set of genes from their parents. This set of genes that an organism receives from its parents is called the genotype of the organism.

However, genes occur in pairs called alleles. In a pair of alleles, one gene is dominant while other is recessive. The dominant gene determines the expressed traits of the individual organism.

This expressed trait of the individual organism as determined by the dominant gene is called the phenotype of the organism.

How many grams are in 2.40 mol of sodium chloride (NaCl)?

Answers

In this question, we are asked to convert from moles to grams.
We have 2.40 moles of NaCl.

We need the molar mass of NaCl. We can calculate this by referencing the periodic table and looking up the atomic weight.
Na = 22.99g
Cl = 35.45g
----------------
+ 58.44g

2.40 moles x (58.44grams) / (1 mole) = 140.26 grams of NaCl

There are 140.26 grams in 2.40 moles of NaCl.
