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.

4NH3(g) + 5O2(g) 4NO(g) + 6H2O(g)
Crazy boy [7]

1. The volume of ammonia consumed in the reaction is 23.2 L

2. The volume of oxygen consumed in the reaction is 29 L

<h3>Balanced equation</h3>

4NH₃(g) + 5O₂(g) --> 4NO(g) + 6H₂O(g)

From the balanced equation above,

6 L of H₂O were produced from 4 L of NH₃ and 5 L of O₂

<h3>1. How to determine the volume of ammonia, NH₃ consumed</h3>

From the balanced equation above,

6 L of H₂O were produced from 4 L of NH₃

Therefore,

34.8 L of H₂O will be produced from = (34.8 × 4) / 6 = 23.2 L of NH₃

Thus, 23.2 L of NH₃ were consumed

<h3>2. How to determine the volume of oxygen, O₂ consumed</h3>

From the balanced equation above,

6 L of H₂O were produced from 5 L of O₂

Therefore,

34.8 L of H₂O will be produced from = (34.8 × 5) / 6 = 29 L of O₂

Thus, 29 L of O₂ were consumed

Given a reaction in which one tin atom that is bonded to two oxygen atoms reacts with 4 hydrogen atoms, which of the following p
alexira [117]

Answer:

A tin atom and 2 molecules containing two hydrogen atoms bonded to one oxygen atom.

Explanation:

Equation of reaction:

SnO2 + 2H2 ---> Sn + 2H2O

According to Dalton's postulates:

1. All elements are made up of small indivisible particles called atoms

2. The atom cannot be created nor destroyed

3. The atoms of the same element are alike in every aspect and differ from atoms of all other elements

4. During a chemical reaction there is a combination of atoms in small whole numbers.

From the given options, the one that satisfies the postulates of Dalton is:

"A tin atom and 2 molecules containing two hydrogen atoms bonded to one oxygen atom"

This is because it gives a balanced chemical equation for the number of atoms reacting for each element is equal to the number of atoms of each element produced. This is in accordance with the postulate that atoms are neither created nor destroyed.

The three other postulates are also obeyed. The small whole number ratio for the reactants and products in the chemical reaction is 1 : 2 : 2.
