Answer:
D. severe weather events would occur more often
Explanation:
If the average global temperatures on Earth increased, there are high chances of severe weather events occurring more often
- Weather events are devastating in nature.
- Examples are hail, blizzards, Lightning and thunderstorm
Increase in average global temperatures can result in these disasters.
When global temperatures increases, polar ice will melt and sea levels will increase.
This will cause storms in coastal areas and flooding.
Answer : The partial pressure of nitrogen gas in the mixture is, 9.88 atm
Explanation :
According to the Dalton's Law, the total pressure of the gas is equal to the sum of the partial pressure of individual gases.
Formula used :
where,
= total pressure of gas = 13.6 atm
= partial pressure of helium gas = 1831 torr = 2.41 atm
= partial pressure of argon gas = 997 torr = 1.31 atm
Conversion used: (1 atm = 760 torr)
= partial pressure of nitrogen gas = ?
Now put all the given values in the above formula, we get:
Thus, the partial pressure of nitrogen gas in the mixture is, 9.88 atm
Answer:
3.68 g
Explanation:
= 18 ÷ 44 = 0.4
2C2H2 + 5O2 → 4CO2 + 2H2O
2 : 5 : 4 : 2
0.409 (moles)
⇒ 
= 0.409 × 2 ÷ 4 = 0.2045 moles
⇒ 
= 0.2045 × 18 = 3.68 grams
A hydrogen fuel cell is more efficient than a combustion reaction because very little of the released energy is released as "Heat". <span>When used at home, a fuel cell eliminates the need for "An Electrical grid"
Hope this helps!</span>
