0.3147128245 moles of AgNO₃ will be needed to completely react with 10.0 g of Cu.
Determine the number of moles of copper by dividing its mass by its molar mass.
moles Cu = mass Cu / MM Cu
moles Cu = 10.0 g/ 63.55 g/mol
moles Cu = 0.1573564123
Based on the balanced chemical reaction between copper and silver nitrate, 1 mole Cu needs 2 moles AgNO₃ to proceed with the reaction completely.
Cu + 2AgNO₃ ⇒ 2Ag + Cu(NO₃)₂
If there are 0.1573564123 moles Cu, then 0.3147128245 moles AgNO₃ is needed.
moles AgNO₃ = 0.1573564123 moles Cu(2 moles AgNO₃ / 1 mole Cu)

what do you think happens to a sound wave when the volume of sound increase
As the volume of the sound is seen to increase, the sound that we hear is louder as the amplitude of the sound increases.
What is sound?Sound is a kind of wave that moves through a medium. We know that sound has to move via several compressions and rare factions. This implies that sound is as well propagated through air. The movement of the sound waves through air is because the air is set into vibration by the sound. Thus, the air is very imprtant in the movement of the sound waves.
With this much said, we can see that if there is more air, there would more molecules that can be set into vibration and the sound wave would tend to increase and that is the deal that we are trying to communicate here.
Thus, the amplitude of air increases as the volume of the sound gets higher and the sound that we hear is much louder.

Volume of a 0.158 m potassium hydroxide solution is required to neutralize 27.5 ml of a 0.361 m nitric acid solution is 0.0159 ml
Volume is the measure of the capacity that an object hold
Here given data is
0.158 m potassium hydroxide solution is required to neutralize 27.5 ml of a 0.361 m nitric acid solution
And the balanced equation is
HNO₃ + KOH → KNO₃ + H₂O
And from the given equation
Mole ratio of acid HNO₃ i.e (nA) = 1
Mole ratio of base KOH i.e (nB) =1
And the molarity of HNO₃ i.e (Ma) = 0.361 m
Volume of base of KOH i.e (Vb) = ?

If the dehydration reaction of an alcohol is successful, the disappearance of an O-H and C-O band from the starting material.
Distinct varieties of alcohols may also dehydrate through a slightly specific mechanism pathway. However, the general idea in the back of every dehydration reaction is that the –OH organization inside the alcohol donates two electrons to H+ from the acid reagent, forming an alkyloxonium ion.
Alcohol dehydration via elimination of water is imperative to a chain of functional group interconversions which have been proposed as a reaction pathway that connects hydrocarbons and carboxylic acids underneath geochemically applicable hydrothermal conditions including in sedimentary basins.
During dehydration synthesis, either the hydrogen of one monomer combines with the hydroxyl group of some other monomer freeing a molecule of water, or two hydrogens from one monomer integrate with one oxygen from the other monomer freeing a molecule of water.

which process requires more energy, melting 380 g of ice or vaporizing 43.0 g of water? the heat of fusion of water is 79.7 cal/g and the heat of vaporization is 540 cal/g. vaporizing 43.0 g of water. melting 380 g of ice.
To vaporize 43.0 g of water, more heat needs to be given as a input for the heat of fusion of water is 79.7 cal/g and the heat of vaporization is 540 cal/g.
The necessary thermal/heat energy input is:
Q ( heat) = (mass of water)(heat of phase transition)
Given: Heat of fusion is 79.72 cal/g
So, heat needed to be supplied to melt solid ( ice) to water is +79.72 cal/g
Similarly, to freeze water to ice ( reverse of fusion), the same heat must be released, that is, heat of freezing = ( - 79.72) cal/g
Heat of vaporisation is 540 cal/g
So, 540 cal/g of heat must be supplied to vaporise water.
And heat change when steam condenses is – 540 cal/g ( - sign implies heat is released).
The question asks for input of energy. So, the corresponding heat change must be positive. Thus, the possible processes are melting and vaporizing.
To vaporize 43.0 g of water, total heat needed to be supplied = (43.0 g )(540 cal/g) = 23220 cal
To melt 380 g of ice: (380 g)(79.72 cal/g) = 30096 cal

1. The answer to the statement above" Is this system at equilibrium " is yes as the reaction rate for both forward and reverse reaction are all equal.
2. From the above given task, as the equilibrium system moves from the reactants to the products, the concentration of the reactants and products are absolutely constant at equilibrium.Why the reaction system above is at equilibrium?It follows that from the reactions above, the concentration of A above is 1.5M and that of B is also 1.5, the resultant concentration is still 1.5M. This implies that the concentration of the A and B are constant throughout in the equilibrium reaction.
The major reason why the concentrations of B and that of A are the same is simply because both the forward and backward reactions are the same in all areas.
The major significance of equilibrium reactions is that it helps us to understand the direction of chemical reaction

The partial pressure of N₂ = 0.158 atm
The partial pressure of H₂ = 3.6 atm
The partial pressure of NH₃ = 0.22 atm
Mass of N2₂ = 4.97 g
Molar mass of N₂ = 28 g/mol
Mass of H₂ = 8.80 g
Molar mass of H₂ = 2 g/mol
Mass of NH₃ = 4.2 g
Molar mass of NH₃ = 17 g/mol
Total pressure (Pt) = 3.97 atm
Partial pressure of N₂ = ?
Partial pressure of H₂ = ?
Partial pressure of NH₃ = ?
First, we will find out the number of moles of each component
Number of moles = mass / molar mass
Number of moles of N₂ = 4.97 g / 28 g/mol
Number of moles of N₂ = 0.1775 mol
Number of moles of H₂ = 8.08 g / 2 g/mol
Number of moles of H₂ = 4.04 mol
Number of moles of NH₃ = 4.22 g / 17 g/mol
Number of moles of NH₃ = 0.2482 mol
Total number of moles = 0.1775 mol + 4.04 mol + 0.2482 mol
Total number of moles = 4.4657 mol
Now find out the partial pressure for each component
partial pressure = number of moles of each / total number of moles × total pressure
partial pressure of N₂ = (0.1775 mol / 4.4657 mol) 3.97 atm
partial pressure of N₂ = (0.0397 mol) 3.97 atm
partial pressure of N₂ = 0.158 atm
partial pressure of H₂ = (4.04 mol / 4.4657 mol) 3.97 atm
partial pressure of H₂ = (0.9047 mol) 3.97 atm
partial pressure of H₂ = 3.6 atm
partial pressure of NH₃ = (0.2482 mol / 4.4657 mol) 3.97 atm
partial pressure of NH₃ = (0.0556 mol) 3.97 atm

The volume of the air collected at the pressure of 150 atm is 13.33 litres.
The ideal gas equation says,
The pressure P, the volume V, the number of moles n, the gas constant R and the temperature t of the gas are related with each other as,
PV = nRT
If the number of moles and the temperature are constant,
PV = Constant
So, we can write,
P₁V₁ = P₂V₂
P₁ is the pressure of the scuba tank is 1 atm and the volume V₁ of the scuba tank is 2000L while P₂ is pressure of the other tank is 150 atm. Hence we can write,

A gaseous solution contains 41% O₂ and 59% N₂ by mass. The mole fraction of Oxygen is 0.377, while the mole fraction of Nitrogen is 0.622 in the solution.
What is the mole fraction of each substance in the solution?
41.0g O₃ X {(1 mol O₃) ÷ (32. 0g O₃)} = 1.28 mol O₃
Where the molecular mass of oxygen is 32
For mole fraction of nitrogen:
