Answer:

1) Well I think you need to research that in G00GLE

Explanation:

2 answer

a) The thinning is most pronounced in the polar regions, especially over Antarctica. Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth's surface, which increases the rate of skin cancer, eye cataracts, and genetic and immune system damage.

b) Seek the shade, especially between 10 AM and 4 PM.

Don't get sunburned.

Avoid tanning, and never use UV tanning beds.

Cover up with clothing, including a broad-brimmed hat and UV-blocking sunglasses.

Use a broad-spectrum (UVA/UVB) sunscreen with an SPF of 15 or higher every day.

Answer:

only sodium chloride compounds MOST LIKELY products of the reaction between sodium metal and chlorine gas.

Correct answer - C

Explanation:

A solid sodium metal reacts with gaseous form of chlorine gas to form a solid sodium chloride.

This formation of sodium chloride arises due to transfer of one valence electron from sodium to chlorine atom and the both atoms get stable octet electronic configuration.

As a result, an ionic compound solid sodium chloride is formed.

The chemical reaction of formation sodium chloride is as follows.

$2Na(s)+Cl_{2}(g) \rightarrow 2NaCl(s)$

Therefore, only sodium chloride compounds MOST LIKELY products of the reaction between sodium metal and chlorine gas.

Answer: There will be 131.3 tons of $SO_{2}$ that will be generated.

Explanation : We have the data as 72 tons of $H_{2}S$ , $O_{2}$ is 101 tons and $H_{2}O$ as 38 tons.

Conversion of 1 ton to kg will be approximately 907.2 Kg

We have to convert the given data of tons into kg for all;

So, moles of $H_{2}S$ = (72 tons X 907.2 Kg/ton X 1000 g/Kg) / (34.082 g/ mol) = 1.916 X $10^{6}$ moles

Now, moles of $O_{2}$ = (101 tons X 907.2 Kg/ton X 1000 g/Kg) / (32 g/mol) = 2.80 X $10^{6}$ moles

And, $H_{2}O$ = (38 tons X 907.2 Kg/ton X 1000 g/Kg) / (18.016 g/mol)

= 1.03 X $10^{6}$ moles

Now, we have to calculate the moles of $H_{2}S$

so, 1.916 X $10^{6}$ moles / 2 moles of $H_{2}S$ = 958 X $10^{3}$

Now, for $O_{2}$ ;

So, 2.80 X $10^{6}$ moles / 3 moles of $O_{2}$ = 933.3 X $10^{3}$ moles

Here, we can see that $O_{2}$ is acting as a limiting reactant.

Now, moles of $SO_{2}$ = 2.80 X $10^{6}$ X (2 moles of $SO_{2}$ / 3 moles of $O_{2}$ ) = 1.86 X $10^{6}$

Now converting this into mass,

Mass = Moles X Molar Mass

Mass = 1.86 X $10^{6}$ X (64.066 g/mol X $10^{-3}$ kg/g) X (1 ton / 907.2 Kg)

= 131.3 tons of $SO_{2}$

What happens in this reaction? butan-1-amine + CH3I -->

Galina-37 [17]

Here we have to get the product between the reaction of butane-1-amine with methyl iodide (CH₃I).

The reaction between 1 mole of butan-1-amine and 1 mole of methyl iodide produces Methyl-butamine which is a secondary amine.

However, In presence of 2 moles of methyl iodide the reaction proceed to N, N-di-methylbutamine. The reaction is shown in the figure.

This is one of the effective reaction method to generate secondary and tertiary amine from primary amine.

The primary amine reacts with alkyl iodide to form secondary to tertiary amine. The final product depends upon the quantity of the alkyl iodide present in the reaction.
