Answer:
molar mass of methane CH4
= C + 4 H
= 12.0 + 4 x 1.008
= 12.0 + 4.032
= 16.042g/mol
7.31 x 10^25 molecules x 1 mole CH4 = 121.43 moles
6.02 x 10^23 CH4 molecules
121.43 moles CH4 are present.
Explanation:
not to certain if this is right or not.. but hope it helps!
Answer:
Urban sprawl is the development in urban areas
Due to which people are migrating from rural areas to urban areas to get the jobs or their income sources due to the opportunities.
So, as population is increasing in the urban areas. The food consumption and water consumption will also increase.
So, this is how urban sprawl affect water consumption.
It changes state
Meaning, it goes from solid to liquid, making it change its state. Hope this helped.
Answer:
Solubility of O₂(g) in 4L water = 3.42 x 10⁻² grams O₂(g)
Explanation:
Graham's Law => Solubility(S) ∝ Applied Pressure(P) => S =k·P
Given P = 0.209Atm & k = 1.28 x 10⁻³mol/L·Atm
=> S = k·P = (1.28 x 10⁻³ mole/L·Atm)0.209Atm = 2.68 x 10⁻³ mol O₂/L water.
∴Solubility of O₂(g) in 4L water at 0.209Atm = (2.68 x 10⁻³mole O₂(g)/L)(4L)(32 g O₂(g)/mol O₂(g)) = <u>3.45 x 10⁻² grams O₂(g) in 4L water. </u>
Soil acidification is a circumstance which will most likely lead to a change in the nutrient cycling that will have a detrimental impact on plant growth.
<h3>What is the main use of nitrogen?</h3>
The chemical industry depends on nitrogen. It is used to create explosives, nylon, nitric acid, fertilizers, and colors. N must first be combined with hydrogen to create ammonia in order to create these products. The Haber process is used for this. Similar to chlorine gas and carbon monoxide poisoning, nitrous oxide poisoning is detrimental to all living things.
<h3>Why is nitrogen poisonous?</h3>
Effects on health. The majority of greater nitrogen oxides are irritants to the eyes, skin, and respiratory system. Except at deadly quantities, where arginine may kill more quickly, no2 is a corrosive chemical that, when in contact with water, produces nitric and nitrous acids.
