oxidation or reduction?

Answers

Answer 1

Answer:

Reduction

Explanation:

Oxidation is a process that involves loss of electrons.

Reduction is a process that involves gain of electrons.

In this equation, the electrons (4e-) are in the reactant side. This means that it is gain of electrons.

The reaction is a reduction reaction.

What is the molarity of a solution made by diluting 0.025L of 6.0 M HCl until
the final volume of the solution is 1.75 L?

Answers

Answer:

Explanation:

Use the dilution equation: M1V1 = M2V2

M1 = 6.0 M

V1 = 0.025 L

M2 = ?

V2 = 1.75 L

(6.0 M)(0.025 L) = M2(1.75 L)

Solve for M2 --> M2 = 0.086 M HCl

What happened during the fusion reaction shown?

Answers

Answer:

the answer to this question B. Two H nuclei that fused into one He necleus

Explanation:

Two hydrogen atoms fused to one helium molecule, hence option B is correct.

What is fusion?

Fusion is defined as a process in which two or more atomic nuclei unite to create new atomic and subatomic particles. Heat, which is produced when two atoms fuse, is the key to generating energy. Similar to how nuclear fission produces energy, this heat can be utilized to warm water, produce steam, and turn turbines to produce electricity.

In the core of the Sun, hydrogen is being converted to helium. This phenomenon is known as nuclear fusion. Fusion is what powers both the sun and the stars. One example of this kind of reaction is when two hydrogen atoms combine to form a helium atom. During the process, a portion of the hydrogen's mass is converted into energy.

Thus, two hydrogen atoms fused to one helium molecule, hence option B is correct.

How many grams of MgBr2 are needed to create 3.0L of a 4.5M aqueous solution of magnesium bromide?

Answers

Answer:

2486 g

Explanation:

First we calculate how many moles of MgBr₂ are required to create such a solution, using the definition of molarity and the given volume and concentration:

Molarity = moles / liters4.5 M = moles / 3.0 Lmoles = 4.5 M * 3.0 L = 13.5 mol

Now we convert 13.5 moles of MgBr₂ into grams, using its molar mass:

13.5 mol * 184.113 g/mol = 2486 g

Because it can identify a person.

DNA Fingerprint

A DNA fingerprint is a piece of DNA so distinct that it can prove a person's identity. These distinct areas can take on many different forms, but each form is unique to any one individual.

PCR allows the amplification of a single copy of DNA into millions of copies. However this technique requires that the DNA of interest already be of a known sequence in order to design primers that will specifically hybridize to the target DNA.

3. How does genetic variation allow humans to survive long-term? Which
type of reproduction is responsible for genetic variation?

Answers

Answer:

more genetic variation within a population usually enables more phenotypic variation.

Explanation:

Because natural selection acts directly only on phenotypes,  Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.

Genetic variation lets the organisms survive long term as it increases the phenotypic and the genotypic variation.  Genetic variation is due to the type of reproduction that involves two parents.

What is genetic variation?

Genetic variation is the modification of the original genome of the organism by genetic recombination and mutation that can be beneficial in the survival and the natural selection process.

Reproduction involving two parents of the same species allow genetic variation as the process of independent assortment and crossing over of the chromosomes inherited from both creates species with different traits and genotype.

Therefore, the reproduction involving two parents results in genetic variation.
