2. The volume of a rock is 5 cm' and its mass is 50 g. Find the density.<br> pls help :)

Vladimir [108]

Answer:

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume}\\$

From the question we have

$density = \frac{50}{5} = 10 \\$

We have the final answer as

3- Fully folded proteins typically have polar side chains on their surfaces, where electrostatic attractions and hydrogen bonds

Elden [556K]

Answer:

Option C= A hydrogen bond formed between a polar side chain and a hydrophobic side chain.

Explanation:

All three given options a, b and d have common mechanism to accommodate the polar amino acid.

A= A hydrogen bond forms between two polar side chains.

B= A hydrogen bond from between a polar side chain and protein back bone.

D = hydrogen bond form between polar side chains and a buried water molecules.

All these are use to accommodate the polar amino acid.

While option C is not used. which is:

A hydrogen bond formed between a polar side chain and a hydrophobic side chain.

M + e- M-1<br><br>Is M oxidized or reduced?

Sergio [31]

Answer: Reduced

Explanation: Oxidation reaction is defined as the reaction in which a substance looses its electron. The oxidation state of the substance gets increased.

$M\rightarrow M^{n+}+ne^-
$

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

$M^{n+}+ne^-\rightarrow M$

Given : $M+e^{-1}\rightarrow M^{-1}$

Thus as in the given reaction the oxidation state of the metal has decreased from 0 to-1, it is getting reduced.
