PV = n RT
P: pressure =10atm
V volume
n number of mole = 35.8 moles
R universal gas constant = 0.082
T: The temperature= 70°C= 343.15 Kelvin

 
V= (n RT) / P = 35.8 x 0.082 x 343.15   / 10 = 100.7 ≈ 101 L

 V = 101L

Answer : The volume of the gas is, 101 liters

Solution :

Using ideal gas equation :

PV=nRT\\\\V=\frac{nRT}{P}

where,

n = number of moles of gas  = 35.8 moles

P = pressure of the gas = 10.0 atm

T = temperature of the gas = 70^oC=273+70=343K

R = gas constant = 0.0821 L.atm/mole.K

V = volume of gas = ?

Now put all the given values in the above equation, we get the volume of the gas.

V=\frac{nRT}{P}

V=\frac{35.8mole\times (0.0821L.atm/mole.K)\times 343K}{10atm}

V=100.81L\approx 101L

Therefore, the volume of the gas is, 101 liters

kondaur [170]

Answer:

Independent: sizes of nails

Dependent: number of paper clips

Controlled: Battery, wire and type of nails

Explanation:

An independent variable is a variable which when changes does not the effect the results of the experiment. It does not depends upon the dependent variable.

A dependent variable is defined as a variable which is affected when the independent variable is changed by the researcher or the experimenter. It depends greatly upon the independent variable.

While a controlled variable is that variable whose value is not changed in an experiment. It contains all the constants.

In the context,

the independent variable are : sizes of nails

the dependent variables are : number of paper clips

the Controlled variables are: Battery, wire and type of nails

Many metals react with acids to produce hydrogen gas. A certain reaction produces 32.6 L of hydrogen gas at STP. How many moles
morpeh [17]

Answer: 1.46moles

Explanation:

Applying PV= nRT

P= 1atm, V= 32.6L, R= 0.082, T = 273K

Substitute and simplify

1×32.6/(0.082×273)=n

n= 1.46moles

Determine Δngas for each of the following reactions:(b) 2H₂(g) + O₂(g) ⇄ 2H₂O(l)
elixir [45]

2H₂(g) + O₂(g) ⇄ 2H₂O(l)

Δngas = 0 - (2 +1)

           = -3

<h3>What is Δngas?</h3>

The number of moles of gas that move from the reactant side to the product side is denoted by the symbol ∆n or delta n in this equation.

Once more, n represents the growth in the number of gaseous molecules the equilibrium equation can represent. When there are exactly the same number of gaseous molecules in the system, n = 0, Kp = Kc, and both equilibrium constants are dimensionless.

<h3>Definition of equilibrium</h3>

When a chemical reaction does not completely transform all reactants into products, equilibrium occurs. Many chemical processes eventually reach a state of balance or dynamic equilibrium where both reactants and products are present.
