Answer:
The number of atoms contained by one molecule of Iron (II) Sulfate are 6.
Explanation:
Iron (II) Sulfate is mage up of two parts. One is the Positive part which constitutes of Fe⁺² and a negative part which constitutes of a polyatomic anion i.e. SO₄²⁻. As there are four Oxygen and one sulfur atom in sulfate Ion so sulfate ion contains 5 atoms in total. Therefore, five atoms from sulfate iona dn one atom of Iron ion makes a total of 6 atoms in one molecule of Iron (II) Sulfate.
The bucket with lead added would replace more water, as it would require more volume to achieve the same mass.
Answer: 600°C
Explanation:
This reaction is explained by Charles' law as the pressure is constant.
From the question, we obtained:
V1 = 67mL
T1 = 18°C = 18 +273 = 291K
V2 = 3V1 ( Vol is tripled) = 3x67 = 201mL
T2 =?
Applying the Charles' law,
V1 /T1 = V2 /T2
67/291 = 201 / T2
Cross multiply to express in linear form.
67xT2 = 291x201
Divide both side by 67, we have:
T2 = (291x201) /67
T2 = 873K
Converting to Celsius temperature, we have
T°C = K — 273
T°C = 873 — 273 = 600°C
Greater the pressure,greater the solubility of gas in a liquid.
Want an example?
Here it is, in the cold drinks we buy, CO2(carbon dioxide) is made soluble under high pressure in the liquid. As soon as we open these cans or bottles, the pressure releases.
Isn't it easy?
