What is the percentage of nitrogen in N2O
Answers
The percentage of nitrogen in nitrous oxide or N₂O is 63.64% and percent of oxygen is 36.36 %.
What is percent composition ?
It is the percent of each element which exists in a compound. It is calculated in three methods:
1) percent w/w
2) percent v/v
3) percent w/v
Percent w/w is the percent composition wherein both the components are solids.Percent v/v is percent composition wherein the 2 substances are liquid and percent w/v is percent composition where one substance is solid and one is in liquid form.
The percent composition of all substances is equal to 100%.The percent composition of nitrogen in nitrous oxide is calculated as follows:
molar mass of nitrous oxide=44 g
molar mass of nitrogen =14 g
As nitrous oxide has 2 nitrogen ,therefore 14×2=28
To find percent composition,
molar mass of nitrogen in nitrous oxide/molar mass of nitrous oxide×100
∴28/44×100=63.64%
Thus, percent of nitrogen in N₂O is 63.64%.

Answer: TRUE
Explanation:
Deductive reasoning is a process in which a conclusion is drawn on the basis of similarities and concordance with pre- proposed principles and multiple premises which are expected and assumed to be true.
In simple words the deductive reasoning is based upon conclusion which is derived from one or more statements or principles which are expected to be true.
On the basis of the above explanation, the statement Drawing a conclusion derived from knowledge of an established principle is called deductive reasoning. is true.

Answer;
pH = 7
Explanation;
- HNO3 is a strong acid. KOH is a strong base. At the equivalence point, the solution will be neutral.
- Therefore; the pH at the equivalence point when 0.10 m HNO3 is used to titrate a volume of solution containing 0.30 g of KOH will be 7.
- The neutralization of a strong base with a strong acid gives a salt solution at the equivalence point. The salt contains ions that do not change the pH of water.
Answer:
pH at equivalence point will be 7
Explanation:
is a strong acid and KOH is a strong base. Hence a neutral salt would appear from acid-base reaction between them.
- Acid-base reaction:
- At equivalence point,
and water exists in medium.
- As
- So, pH at equivalence point will be 7.

Answer:
HNO3 ->NO3²- + H+
Concentration of H+ ions= 0.0032M
pH = - log[ H+]
= - log (0.0032)
= 2.49
pH + pOH = 14
pOH = 14 - pH
= 14 - 2.49
= 11.51
pH = 2.49 and pOH = 11.51

B. actually double.
C. remain the same, plus interest.
D. be two hundred dollars.
Answers
The answer choice is B) It should actually double.
Considering it's been in the bank so long, it would have increased because of interest rates.

A weather front or front is a narrow region between two air masses of different densities. Because of the difference in density between warm and cold front, cold air tends to go underneath the warmer air. It often creates the strongest winds above the ground surface. This is caused due to the heat and mass transfer between particles of air. They can be slowed down by the presence of mountains and valleys. Cold air moves fast and the temperature around it can be felt as if you are blown away due to its density. Whereas warm air moves slowly.
