Answer:
0.175mol
Explanation:
Molarity of a solution can be calculated thus:
Molarity (M) = number of moles (n) / volume (V)
According to the information provided in this question, volume of NH4OH = 0.125L, molarity = 1.4M
Using; Molarity = n/V
1.4 = n/0.125
n = 0.175mol
Answer:
C₄H₄N₂
Explanation:
Given that:
M+ = 80.
It implies that the number of nitrogen present in the molecule must also be even according to the Nitrogen rule.
So from the Formula CHN, the nitrogen will have to be 2 because if we make use of 4, it will exceed the given M+ which is 80.
∴
C₄ = 4 × 12 = 48
H₄ = 4 × 1 = 4
<u>N₂ = 2 × 14 = 28 </u>
<u> 80 </u>
As such, the molecular formula of the compound is C₄H₄N₂
Answer: The third one 0.750 L
Explanation: 1,000 Millilitres equal 1 Liter
500 + 250 = 750 (Not A Liter)
So 0.750 L
Answer:
These air pollutants consist of...
- Carbon monoxide
- Nitrogen oxides
- Climate change
- Fossil fuels
- Organic compounds. <em>Just because they are organic does not mean they are good for the environment.</em>
