Answer:
Zn(NO₃)₂
Explanation:
this single replacement reaction will produce silver metal, Ag , and aqueous zinc nitrate, Zn(NO3)2 . Zinc is above silver is the metal reactivity series, so it will replace silver in silver nitrate
C & B are switched so I'm not sure if that was a typo or not, but the answer is concentration!
Answer:
a) No. of moles of hydrogen needed = 5.4 mol
b) Grams of ammonia produced = 27.2 g
Explanation:
a)
No. of moles of nitrogen = 1.80 mol
1 mole of nitrogen reacts with 3 moles of hydrogen
1.80 moles of nitrogen will react with
= 1.80 × 3 = 5.4 moles of hydrogen
b)
No. of moles of hydrogen = 2.4 mol
It is given that nitrogen is present in sufficient amount.
3 moles of hydrogen produce 2 moles of 
2.4 moles of hydrogen will produce
= 
Molar mass of ammonia = 17 g/mol
Mass in gram = No. of moles × Molar mass
Mass of ammonia in g = 1.6 × 17
= 27.2 g
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.
