Answer:
(i) Al2(SO4)3
(ii) CaCl2
(iii) Fe(OH)2
(iv)AlPO4
(v) Fe(NO3)3
(vi) AuCl3
(vii) AgNO3
Explanation:
The numbers after the element/ion is a subscript meaning its put below the symbol
(i) Al has a charge of 3+ and SO4 has a charge of 2-
So to balance the charges 2 Al is needed to make the charge a 6+ and 3 SO4 is needed to make the charge a 6-. Once you can add the two charge values together to create 0, then you have the correct quantities
(ii) Same applies here, but Ca is 2+ and Cl is 1-, so 2 Cl- is needed to balance out the Ca
(iii) Ferrous is an ion of Iron with a 2+ charge, the other ion of Iron is Ferric which has a 3+ charge. OH has a charge of -1, so 2 OH is needed to balance out one Fe
(iv) Aluminum again has a charge of 3+ while PO4 has a charge of 3-, so they both balance out with one of each.
(v) Ferric is an ion of iron with a charge of 3+ and NO3 has a charge of 1-, so three of NO3 is needed to balance.
(vi) Gold has two charges, 1+ or 3+. However used in Gold chloride it is a 3+ and Cl is a 1-, so 3 of Cl is needed to balance one gold.
(vii) Silver has a charge of 1+ while NO3 has a charge of 1-, so they balance each other at one each.
Answer: 2.58L
Explanation:
We must convert the temperature from °C to Kelvin temperature
T1 = 40°C = 40 + 273 = 313K
V1 = 2.32 L
T2 = 75°C = 75 + 273 = 348K
V2 = ?
V1 /T1 = V2 /T2
2.32 / 313 = V2 / 348
Cross multiply to express in linear form
313 x V2 = 2.32 x 348
Divide both side by the coefficient of V2 ie 313. We have
V2 = (2.32 x 348) /313
V2 = 2.58L
Therefore, if the temperature is raised to 75°C, the volume of the gas will be 2.58L

Answer:
unsaturated fatty acid are liquid in nature, posses multiple bond in it's structure where as saturated fatty acid are solid in nature, have only single bonds in it's structure.
The Scientific Method organized the way scientist conducted experiments. It became safer and less chaotic as the Scientific Method gave them a plan of action throughout any and all experiments.
