Answer:
the water cycle is a system that goes through evaporation then the water goes into the clouds and rains down as preparation
Explanation:
thats the cycle but if I were u I would do more Reasearch
5.6 atm
In a container, the sum of partial pressures equals the total pressure. If the sun is 9.8 atm and the partial pressure of oxygen is 4.2 atm, the rest of the gases must account for the other 5.6 atm.
The number of moles of NO₂ that would be produced from 3.9 mol of O₂ in the reaction is 5.13 moles NO2.
<h3>What is nitrogen?</h3>
Nitrogen is a monatomic gas. It is the most abundant gas present in the environment.
4.5 mol O2 x (2 mol NO2/ 1 mol O2) = 9 mol NO2
For 57% yield of the reaction
9 mol NO2 x 0.57 = 5.13 moles NO2.
Thus, the number of moles of NO₂ is 5.13 moles.

Potassium is an element with a symbol of K. When it forms an oxide, it means that it has undergone combustion. The complete reaction for this is
K + O₂ ⇒ K₂O
This is a combination reaction which involves two reactants and one single product. It is important to note that the Law of Conservation of Mass mass be obeyed at all times. Technically, the law involved in balancing reactions is the Law of Definite Proportions. This is obeyed by making sure that the number of a specific element is the same before and after the reaction. So, the complete balanced reaction for this is
2 K + 1/2 O₂ ⇒ K₂O
The coefficient of O₂ in the reaction is 1/2.
<u>Answer</u>
79 ml
<u>Explanation</u>
You have 237 237 ml of ammonia, whose strength is 100%.
If you want to make it 75%, then;
let 75% ⇒ 237 ml of ammonia and
25% ⇒ x ml of water.
∴ x = (25% ×237) / 75%
= 5,925/75
= 79 ml of water.
