1 mole ------------- 6.02x10²³ molecules
?? moles ---------- 2.0x10²² molecules

( 2.0 x 10²² ) x 1 / 6.02x10²³ => <span>0.0332 moles of water</span>

Solve this word problem:
valina [46]

Answer:

The new acceleration becomes twice the pervious acceleration.

Explanation:

Given that,

Mass of the rock, m = 3 kg

Force, F = 1 N

We know that the force acting on an object is given by :

F = ma

a is acceleration of the rock

Put m = 3 kg and F = 1N,

a=\dfrac{F}{m}\\\\a=\dfrac{1}{3}\ m/s^2

If the force is doubled, F' = 2 N

So,

F'=ma'

a'=\dfrac{F'}{m}\\\\a'=\dfrac{2\times 1}{3}\\\\a'=\dfrac{2}{3}\\\\a'=2\times \dfrac{1}{3}\\\\a'=2a

So, the new acceleration becomes twice the initial acceleration.

Compare and contrast the positive and negative effects that result from the use of the Haber process.
Luda [366]

Answer: Positive effects: mass production of fertilizers, alkaline cleansers, refrigerant gas, dyes, explosives

Negative effects: heath problems, negative effects on soil organisms and soil organic matter,  imbalances to the nitrogen cycle, high fossil fuel energy inputs, production of deadly weapons

Explanation:

The Haber process (also called Haber Bosch process) is used to produce ammonia from nitrogen and hydrogen under the high pressure. Basically, it's an artificial nitrogen fixation process. This method has both positive and negative effects on modern society.

Positive sides: ammonia is mainly used for mass production of fertilizer, which allows more food for everyone. It can be used for production of alkaline cleansers, refrigerant gas, dyes and explosives. Ammonia is also used in production of synthetic polymers, due to its role in the manufacturing of cyanide.

Negative sides: ammonia is a toxic gas, it can irritate eyes and lungs. Because of that, the excess nitrogen in soil and water coming from synthetic fertilizers can cause health problems. It is harmful for humans and animals, but it can also be harmful for plants. Environmental factors are also important. Because of the mass fixation, there is imbalance in the earth’s nitrogen cycle. Also, fossil fuels are used as a source of power for machinery in Haber's process, which increases emissions into the atmosphere. And, at least ammonia is a major component of weapons including great number of bombs.
