What is the total pressure exerted by a mixture of 48.0 grams of CH4 and 56.0 grams of

Chemistry
1 answer:
Oksi-84 [34.3K]1 year ago
4 0

The pressure of the gas is obtained as 48 atm.

<h3>What is the total pressure?</h3>

Now we know that;

Number of moles of CH4 = 48.0 grams /16 g/mol = 3 moles

Number of moles of H2 =  56.0 grams/2 g/mol = 28 moles

Total number of moles present = 3 moles + 28 moles = 31 moles

Using;

PV =nRT

P = total pressure

V = total volume

n = total number of moles

R = gas constant

T = temperature

P = nRT/V

P = 31 * 0.082 * 286/15

P = 48 atm

Find the molarity of a solution made by dissolving 12.5 g sodium carbonate in 500.0 mL total solution
Over [174]

Answer:

The molarity of a solution is "25 M".

Explanation:

The given values are:

Moles of solute,

= 12.5 g

Volume of solution,

= 500 mL

i.e.,

= 0.5 L

Now,

The molarity will be:

=  \frac{Number \ of \ moles \ of \ solute}{Volume \ of \ solution}

On substituting the values, we get

=  \frac{12.5}{0.5}

=  25 \ M

During the isothermal heat addition process of a Carnot cycle, 900 kJ of heat is added to the working fluid from a source at 400
Alinara [238K]

Answer:

the entropy change of the fluid during the process process is is 1.337 kJ/K, the change for the source is -1.337 kJ/K and the total entropy change is 0

Explanation:

since the Carnot cycle is a reversible cycle, the entropy change is related with the heat exchanged through:

ΔS =∫dQ/T

since the temperature remains constant

ΔS =∫dQ/T=(1/T)*∫dQ = Q/T

Q= heat added to the system

T= absolute temperature = 400°C= 673 K

therefore

ΔS = Q/T = 900 kJ/ 673 K = 1.337 kJ/K

ΔS working fluid = 1.337 kJ/K

since the process is reversible, the entropy change of the universe (total entropy change)  is 0 (there is no entropy generation). thus

ΔS universe = ΔS working fluid + ΔS source = 0

ΔS source= -ΔS working fluid = -1.337 kJ/K

The thermal stability of group 2 hydroxides increases down the group ? give reasons​
VladimirAG [237]

ANSWERS:

Group 2 metal carbonates, nitrates and hydroxides decompose to heat to give the corresponding metal oxide and release CO2, NO2 and O2, and H2O respectively. The thermal stability increases down the group as theionic character of the compounds increases down the group.
