Which of the following is not a result of air pollution? A. Smog
B. Breathing problems
C. Global warming
D. Soil erosion

Answers

Answer 1

Answer: Smog is the combination of smoke and fog. Smokeis the result of human activity such as burning of wood, coal, etc. This is aresult of air pollution. Breathing problems are the effects of air pollutionbecause it destroys the respiratory system. Global warming is also an effect ofair pollution. The consecutive production of carbon monoxide fromtransportation vehicle, mismanagement of garbages contributes to globalwarming. Soil erosion however is the result of fluid always passing on to thatarea. This is not the result of air pollution. The answer is letter d.

Answer 2

Answer: D is the answer....all otherr are a result of pollution

They cannot, because then at room temperature metals would not be solid. THey would be in a liquid state.

Given the incomplete equation for the combustion of ethane:2C2H6 + 7O2==>4CO2 + 6 ____
What is the formula of the missing product?
(1) CH3OH (3) H2O
(2) HCOOH (4) H2O2

Answers

Answer : The correct option is, (4) $(H_2O)$

Explanation :

Combustion reaction : It is a reaction in which a hydrocarbon react with the oxygen gas to produces carbon dioxide as water as a products.

The given incomplete equation are :

$2C_2H_6+7O_2\rightarrow 4CO_2+6_$

In this equation, we see that a hydrocarbon and oxygen gas are present on reactant side and carbon dioxide are present on product side but water molecules are missing on the product side. So, we are adding water $(H_2O)$ on missing side.

The given complete equation will be :

$2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O$

Therefore, the formula missing on product is, $(H_2O)$

The combustion of ethane will consume oxygen and create carbon dioxide and water. That is a general rule for most alkane, olefin and alkyne. So the missing product is H2O.

What is the difference between neutralization and saturation?

Answers

Neutralization deals with the buffering or neutralizing of acids and bases. You change the pH of either an acid or a base by adding H+ ions to a base solution or adding OH- ions by adding a base(alkali) to an acid solution. Ideally you are neutralizing either one to a neutral pH condition which is "7" on the pH scale.

Saturation on the other hand deals with how much solute (solid) you can disolve in a solvent. As you add solute to solution it can only disolve a certain amount before the solvent becomes "satutated" and no more solute will desolve into a homogenous blend with the solvent. You then see precepitants start coming out of solution and falling to the bottom of the container the solution is contained in.

Explanation:

A sealed container has 1 mole of helium and 2 moles of nitrogen at 30DC when the total pressure of mixture is 0.60 atm what is the partial pressure of the nitrogen?

Answers

Answer:

The partial pressure of nitrogen is 0.402 atm.

Explanation:

Given data:

Number of moles of helium = 1 mol

Number of moles of nitrogen = 2 mol

Total pressure of mixture = 0.60 atm

Partial pressure of nitrogen = ?

Solution:

First of all we will calculate the mole fraction of nitrogen.

mole fraction of nitrogen = moles of nitrogen / total number of moles

mole fraction of nitrogen = 2 mol / 3 mol = 0.67

Partial pressure of nitrogen:

P₁ = [ n₁ /n(t)] × Pt

P₁ = 0.67 × 0.60 atm

P₁ = 0.402 atm

Final answer:

To find the partial pressure of nitrogen in a mixture, calculate the mole fraction of nitrogen and multiply it by the total pressure of the mixture. In this case, the partial pressure of nitrogen is 0.40 atm.

Explanation:

The question is about determining the partial pressure of nitrogen in a mixture of helium and nitrogen based on Dalton's Law of Partial Pressures. First, we find the mole fraction of nitrogen, which is the ratio of moles of nitrogen to the total moles in the mixture. In this scenario, the mole fraction (XN2) is 2 moles of nitrogen divided by the total moles (1 mole of helium + 2 moles of nitrogen), which equals 2/3.

Then we use Dalton's Law, which states that the partial pressure of nitrogen (PN2) can be found by multiplying the mole fraction by the total pressure of the mixture. Therefore, the partial pressure of nitrogen is 0.60 atm (total pressure) multiplied by 2/3 (mole fraction of nitrogen), yielding a partial pressure for nitrogen of 0.40 atm.
