Answer:
See below
Explanation:
1 year is how many seconds ?
1 year :
365 days/ yr * 24 hours / day * 60 min/ hour * 60 seconds/ min
=====
see how the 'days' 'hours' 'min' all cancel and you are left with
'seconds' / 'year' ? = 31 536 000 seconds/year
Answer: 3.52 grams
Explanation:

Given moles:
moles of oxygen = 6.62
moles of 
According to stoichiometry:
2 moles of benzene reacts with = 15 moles of oxygen
Thus 0.08 moles of benzene will react with =
moles of oxygen
Thus benzene is the limiting reagent as it limits the formation of products and oxygen is the excess reagent.
As 2 moles of benzene produce = 12 moles of carbon dioxide
0.08 mole of benzene will produce =
of carbon dioxide
Mass of carbon dioxide=
Thus 3.52 g of carbon dioxide are produced.
C is the correct answer
both metals and non-metals
like Boron(B) and Silicon(Si)
good luck
Answer:
We get ammonia because the forward and reverse reactions are happening at the same rates.
If 3 mol of
H
2
is mixed in a sealed vessel with 1 mol
N
2
under suitable conditions then they will react to form ammonia
N
H
3
:
N
2
+
3
H
2
→
2
N
H
3
At the start of the reaction the concentration of the
N
2
and
H
2
are high. As soon as some
N
H
3
is formed the reverse reaction will start to occur:
2
N
H
3
→
N
2
+
3
H
2
The rate of the reaction depends on concentration so the forward reaction will be fast at first when the concentration of the reactants is high. It will slow down as their concentration decreases.
By the same reasoning the reverse reaction will be slow at first then increase. These two processes continue until a point is reached when the rates of the forward and reverse reactions are equal.
We now state that the reaction has reached equilibrium which we show by:
N
2
+
3
H
2
⇌
2
N
H
3
It is described as "dynamic" because the forward and reverse reactions are happening at the same time although the concentrations of all the species remain constant.
So although
N
H
3
is constantly breaking down, more is being formed at a constant rate.
In the Haber Process the system is actually not allowed to completely reach equilibrium as the process is continuous, as described in Mukhtar's answer.
