Answer:
When factories mass produce something it produces smoke. That smoke can be harmful to something called the ozone layer. The ozone layer is part of earth's atmosphere that protects us from the suns burning heat. When that layer is damaged the sun's heat burns through heating up the world and melting ice causing the water levels to rise. All of this can make working conditions less safe, cause more flooding, and have the sun cause cancer.
Answer:
iron = 15000 kg 95% sulfuric acid = 27646.32 kg
Explanation:
The molar volume to a gas is 22.4 L, which means that a mole of a given gas at 0°C and 1 atm will have a volume os 22.4 L.
1 m3 - 1000 L
4870 m3 - x
x = 4870 * 1000 = 4.87 *10^6 L
1 mole - 22.4 L
y mole - 4.87 * 10^6 L
y =
= 2,17 *10^5 moles (if 100% of the H2 is used)
as 20% of it is lost, we need to know how much more we need to use.
80% - 2.17 * 10^5 moles
100% - z
z =
= 2,68*10^5 moles
so we would need 2.68*10^5 moles of iron and sulfuric acid.
1 mole of iron - 56 *10^-3 kg
2.68*10^5 moles - t
t= 2.68*56 *10^2 = 15000 kg
1 mole of sulfuric acid - 98 * 10^-3 kg
2.68*10^5 - u
u = 2.68*98 *10^2 = 26264 kg (if 100%)
95% - 26264 kg
100% - v
v =
= 27646.32 kg
Answer:
Answer in explanation
Explanation:
In the first case, we divide each of the masses by the respective atomic masses:
N =0.615/14 = 0.043928571428571
O = 0.703/16 = 0.0439375
It can be seen here that the values are similar, hence the formula is NO
now let us look at the second data set:
N = 1.27/14 = 0.090714285714286
O = 2.9/16 = 0.18125
We now divide by the smallest
N = 090714285714286/090714285714286 = 1
O = 0.18125/090714285714286 = 2
The formula here is thus NO2.
It can be seen that there are different oxides of nitrogen here which clearly indicates the law of multiple proportion.
