Answer:
Option A = 17.03 g/mol
Explanation:
Given data:
Atomic mass of nitrogen = 14.01 g/mol
Atomic mass of hydrogen = 1.008 g/mol
Molecular mass of NH₃ = ?
Solution:
Molecular mass of NH₃ = (14.01 g/mol × 1) + (1.008 g/mol × 3)
Molecular mass of NH₃ = 14.01 g/mol + 3.024 g/mol
Molecular mass of NH₃ = 17.03 g/mol
Ammonia consist of hydrogen and nitrogen both are nonmetals that's why ammonia is an covalent compound.
Answer:
The new temperature is 894 K or 621 °C
Explanation:
Step 1: Data given
Initial volume of the container = 2.000L
Initial temperature = 25.0 °C = 298 K
Volume increased to 6.00 L
Step 2: Calculate the new temperature
V1/T1 = V2/T2
⇒with V1 = the initial volume = 2.00L
⇒with T1 = the initial temperature = 25 °C = 298 K
⇒with V2 = the increased volume 6.00 L
⇒with T2 = the new temperature
2.00 L / 298 K = 6.00 L / T2
T2 = 894 K = 621 °C
The new temperature is 894 K or 621 °C
222.5 g
I did it like this:
X/250= 89/100=
22250/100=
222.5
Answer: Acid rain.
Explanation:
According to some experts, acid precipitation can lead to acid rain. Acid rain is a product of chemical reactions caused by the release of compounds such as sulfur dioxide and nitrogen oxides into the air. These substances can form in the atmosphere itself and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
There are specific theories that nitrogen oxides cause acid rain, in other sulfur oxides, which are produced by the combustion of coal or petroleum products, for example, in thermal power plants, automobile engines, and plants for the production and purification of metals. With water vapor, they produce nitric or sulfuric acid, respectively. This natural disaster is very bad for flora and fauna, it has a particular negative reflection on forests and the aquatic world, especially fish.
This is classified as a "Formation Reaction"
