How does an increase in temperature affect a gas when the volume is fixed? (Fixed means it stays the same.)

Ber [7]

An increase in temperature at constant volume will increase the kinetic energy and the distance. Thus, option c is correct.

<h3>What is Gay-Lussac's law?</h3>

Gay-Lussac's law is the ideal gas law that defines the direct relation of the temperature to the pressure of the gas at a constant volume.

With an increase in the temperature of the gas, the pressure also rises causing the distance between the particle to expand by the increase in the kinetic energy.

Therefore, option c. the kinetic energy, particle distance, and the pressure increases with tempearture rise.

Which atoms has the same numbers of protons and neutrons

Luda [366]

Explanation:

Generally, the light nuclei atoms have the same number of protons and neutrons in the nuclear composition. They have a proton to neutrons ratio of almost or equal to 1 because in such a way the nucleus can achieve stability.

DNA can be replicated through an in vivo mechanism or a polymerase chain reaction (PCR) mechanism. Match each description to the

umka2103 [35]

Complete question from other source attached

Answer:

Explanation:

Catalyzed by DNA polymerase - both. DNA polymerase catalyzes DNA replication in the cell. However, purified versions of the enzyme are also used to synthesise DNA as part of PCR reactions

involves leading strand synthesis only - PCR. In PCR, lagging strand synthesis is not carried out because the DNA is denatured (rendered single stranded). Therefore, each strand is replicated independently by leading strand synthesis

duplicates a small fragment of the genome - PCR. Usually, to carry out PCR, small sequences called primers are used that specify the region of DNA to be replicated

duplicates the entire genome - in vivo replication - when the DNA is replicated in vivo, the entire genome is replicated. This is carried out prior to cell division so that two daughter cells can each inherit a copy of the entire genome

What is the volume of a 16.24 g sample of magnesium in cubic centimeters? Show a numerical setup and result for credit.

Virty [35]

Answer:

9.34 cm³

Explanation:

From the question given, we obtained the following data:

Mass of magnesium = 16.24 g

Volume of magnesium =.?

To obtain the volume of the magnesium sample, we simply apply the formula for calculating the density of samples. This is illustrated below:

Mass of magnesium = 16.24 g

Density of magnesium 1.738 g/cm³

Volume of magnesium =.?

Density = mass /volume

1.738 = 16.24/volume

Cross multiply

1.738 × volume = 16.24

Divide both side by 1.738

Volume of magnesium = 16.24/1.738

Volume of magnesium = 9.34 cm³

Therefore, the density of the magnesium sample is 9.34 cm³.
