Explanation:
mole of acid/mole of base=(concentration of acid×volume of acid)/(concentration of base×volume of base)
Na/Nb=CaVa/CbVb
1/2=(Ca×16.7)/(0.2×25)
0.2×25=2×Ca×16.7
Ca=(0.2×25)/(2×16.7)
Ca=0.15mol/dm³
mole of acid=Concentration×volume
mole of acid=0.15×(16.7/1000)
mole of acid=2.5×10^-3moles
Answer:
a. 0.171M
b. 0.0938M
c. 0.284
d. 1.99atm
e. 1.88
Explanation:
Hello,
In this case, for the given reaction whose balance should be corrected as:
For which the law of mass action, in terms of the change due to stoichiometry and the reaction extent, turns out:
Thus, the initial concentration of hydrogen sulfide is:
Now, since the equilibrium amount of sulfur is given, the change due to equilibrium reaching is:
Therefore:
a. Equilibrium concentration of hydrogen:
b. Equilibrium concentration of hydrogen sulfide:
c.) Equilibrium constant, Kc:
d.) Partial pressure of sulfur gas:
e. Kc, for the reaction:
In that case, it equals the inverse halved initial reaction, whose modification is related as:
Best regards.
Think about a balloon. if you blow too much air into it and give it too much pressure, the balloon will pop. it’s kind of like that.

Answer:
Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide and water vapor.Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels.Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapor accounts for about 50 percent; and clouds account for 25 percent.Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating
