Estimate the yearly increase in the average atmospheric concentration of carbon dioxide. Express the answer in parts per million

.
Chemistry
1 answer:
alexgriva [62]3 years ago
7 0

Answer:

1.3 ppm per year.

Explanation:

Carbon dioxide is released in the air which causes atmospheric pressure on the earth. Over the past 150 years the increase in average atmospheric concentration of carbon dioxide is 280 to 380 parts per million or ppm. The concentration rise in carbon dioxide will create a burden on ozone layer of the earth. Carbon dioxide atmospheric concentration varies during ice ages. The climate change has resulted in frequent fluctuation due to this reason.

A certain liquid X has a normal boiling point of 111.20 celsius and a boiling point elevation constant Kb=0.95. calculate the bo
Goshia [24]

Answer: the boiling point is = 137.325°C

Explanation:

From the formula: ∆Tb= Kb*m

From the question, Kb= 0.95, m= 27.5, T1= 111.2°C

Substitute into ∆Tb= Kb*m

∆Tb= 0.95*27.5= 26.125

∆Tb= T2-T1

Hence

T2- 111.2=26.125

T2= 26.125+ 111.2= 137.325°C

denis23 [38]

Answer:

The pH of the solution is basic

Explanation:

as one of the characteristics of the base is to increase the OH concentration in a solution so if the solution has low concentration of OH this means that the solution is basic

The relatively high boiling point of water is due to water having
Verizon [17]
The answer should be hydrogen bonding. Water only has oxygen and hydrogen in it, which are both nonmetals, so you know the answer cannot be metallic or ionic. It also cannot be nonpolar because the electronegativity of the oxygens will make the molecule polar. You can also know it is hydrogen bonding because it can only take place when a hydrogen is attached to an oxygen, fluorine, or nitrogen. These bonds are very strong attractions, so the molecules are extremely hard to pull apart, creating a high boiling point. Hope that helps!

If Oxygen were to gain 2 electrons, the new electron configuration for the oxide ion
Naddika [18.5K]
It would be most similar to neon. it wouldn’t be sulfur because that’s in the same group as oxygen and has the same number of electrons. and carbon has less than that so the only one that makes sense is neon
