Answer:
Gallium - Phosphorous - Fluorine - Chlorine
Explanation:
Answer: nothing. It remains undissolved
Explanation: saturated = dissolved as much solute as solvent can contain
Answer:
ΔH = -976.5 kJ
Explanation:
For the reaction given, there are 2 moles of benzene (C6H6). The heat of this reaction is -6278 kJ, which means that the combustion of 2 moles of benzene will lose 6278 kJ of heat. It is an exothermic reaction.
The value of ΔH, the enthalpy, is a way of measurement of the heat, and it depends on the quantity of the matter (number of moles).
So, 24.3 g of benzene has :
n = mass/ molar mass
n = 24.3/78.11
n = 0.311 moles
2 moles ------------ -6278 kJ
0.311 moles ----------- x
By a simple direct three rule:
2x = -1953.08
x = -976.5 kJ
The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.
The balanced chemical equation for the dissolution of silver nitrate has been:
The aqueous solution of silver nitrate has been dissociated into the constituent silver and nitrate ions.
In a balanced chemical equation, the coefficient has been equivalent to the moles of each reactant forming the moles of product.
From, the balanced equation,
The given moles of Silver has been 0.854 mol. Thus, the moles of silver nitrate required has been given as:
The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.

Answer:
Charles's law
Explanation:
The expression:
V1/T1 = V2/T2
represents Charles's law
The law states that "the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant".
So,
V1/T1 = V2/T2
Pressure and the number of moles are constant
V and T are the volume and temperature
1 and 2 are the initial and final states.
