Answer:
2, 2, 1
Explanation:
The coefficient of H₂O will be 2 because we have 2 oxygens on the right side but only one on the left side. Now, we have 4 hydrogens on the left side but only 2 on the right side. To balance, we'll add a 2 as the coefficient of H₂. We don't need to change the coefficient of O₂ because the equation is already balanced.
Final answer, 2, 2, 1.
Answer:
→
Explanation:
→
On the left you have:
Na: 1
Br: 2
On the right you have:
Na: 1
Br: 1
To get the Br to be the same on both sides, you would multiple the NaBr by 2. Then, you will have 2 Na so you put a coefficient of 2 in front of the Na aswell.
Answer is given below
Explanation:
given data
weight = 6N
temp = 105° C
weight reduced = 5N
solution
weight of container is 1N
SO W = (6-1) = 5
And Wd = 5 - 1 = 4
so
moisture content is
moisture content = .......1
moisture content =
moisture content = 25%
and
as we know density of soil soild = 2700 kg/m³
density of water = 1000 kg/m³
and sp gravity of soil = = 2.7
so
now we get here bulk unit weight
bulk unit wt = ..........2
bulk unit wt =
bulk unit wt = 19.766 KN/m³
and
so dry unit wt will be
dry unit wt = ..............3
dry unit wt =
dry unit wt = 15.813 kN/m³
Each mole of nitrogen produces 2 moles of ammonia.
One mole of gas occues 22.4 liters under STP.
Moles of ammonia = 100/22.4
= 4.46 moles
Moles of nitrogen required = 4.64/2
= 2.32 moles
Mass = moles x Mr
Mass of nitrogen = 2.32 x 28
= 64.96 grams
I would say the answer is C.
