The theoretical mass of silver that will be produced is calculated as follows
write the reaction equation
Cu + 2Ag(No3) ---> 2Ag + Cu(NO3)2
calculated the moles of each reagent
moles =mass/molar mass
Cu = 6.51g/63.5g/mol= 0.103 moles
Ag(NO3)2 = 28.4 g/169.87g/mol = 0.167 moles
Cu is the limiting reagent therefore the moles Ag= 2 x0.167 = 0.334 moles
mass = moles xmolar mass
0.334mol x 107.87g/mol = 36.02 grams
Solution :
Compound Ksp
FeS
Ksp of and both compounds dissociate the same way. Hence is more soluble than
is less soluble than
It is not possible to determine CD - is more or less soluble than as though they have a different Ksp values their molecular dissociation is also different and they may have a close solubility values.
can be directly compared with PbS,

1-s s 2s
Ksp =
Hence they can be directly compared by Ksp values, smaller the Ksp, smaller the solubility.
For Silver Chloride

1 - s s s
Ksp
Hence, they can be directly compared by Ksp values, smaller the Ksp, smaller the solubility.
The term that identifies the amount of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius is Specific heat capacity.
<h3>
What is specific heat capacity?</h3>
Specific heat capacity is the quantity of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius. The unit of specific heat capacity is joule per gram per degree Celsius (J/g⁰C).
<h3>Difference between
heat capacity and
specific heat capacity</h3>
Specific heat capacity is heat required to raise the temperature of a unit mass of a substance while heat capacity is the quantity of heat required to raise the temperature an entire mass of a substance.
Heat capacity is measure in Joules (J) while specific heat capacity is measured in joule per gram per degree Celsius (J/g⁰C).
Thus, the term that identifies the amount of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius is Specific heat capacity.

Answer:
Explanation:
Before writing this equation in a molecular equation form, let's identify each species:
- phosphorus is a non-metal represented by 'P', it is solid at standard conditions;
- iron(III) oxide is an ionic compound consisting of iron(III) cations with a 3+ charge, as well as of oxide anions with a 2- charge, this means we may represent it as , which is also a solid material at standard conditions;
- tetraphosphorus decoxide consists of 4 phosphorus atoms and 10 oxygen atoms, as stated by the prefixes, this is also a solid;
- iron metal is simply 'Fe'.
Putting all of this into a single equation and balancing it, we obtain:
Using the given formula, the density of the material is 2.015 g/mL
<h3>Calculating Density </h3>
From the question, we are to determine the density of the material
From the given formula
Density = Mass / Volume
And from the given information,
Mass = 65.5 g
and volume = 32.5 mL
Putting the parameters into the equation,
Density = 65.5/32.5
Density = 2.015 g/mL
Hence, the density of the material is 2.015 g/mL.
