D = m / V
D = 2790 g / 205 mL
D = 13.60 g/mL
Answer:
The correct answer is option B.
Explanation:

Moles of
= 40 mol
Moles of NaOH = 48 mol
According to reaction, 3 moles of NaOH reacts with 2 moles 
Then ,48 moles of NaOH will reacts with:
of 
Then ,40 moles of
will reacts with:
of NaOH
As we can see that 48 moles of sodium will completey react with 32 moles of nitrogen tribromide.
Moles left after reaction = 40 mol - 32 mol = 8 mol
Hence, the
is an excessive reagent.
Answer:
Collection - Evaporation - Condensation - Precipitation
Explanation:
The Water cycle is a series of continuous events that cause rain
We know, It's atomic formula = C4H10
Now, we know molar mass of C = 12 & H=1
so, it would be: 12*4+1*10 = 48+10 = 58
