To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

We are given:

$P_1=6.5atm\\T_1=22^0C=(22+273)K=295K\\P_2=?\\T_2=50^0C=(50+273)K=323K$

Putting values in above equation, we get:

$\frac{6.5}{295}=\frac{P_2}{323}\\\\P_2=7.1$

Hence, the new pressure is 7.1 atm

How many grams of oxygen are needed to

Paraphin [41]

Answer:

The value is $M_{o} = 175 g$

Explanation:

Generally the reaction between oxygen and magnesium is

$2Mg_{({s})} + O_2_{(g)} \to 2MgO_{(s)}$

Generally from the law of mass conservation in a chemical reaction we have that

$M_{m} + M_{o} = M_{z}$

Here $M_{m}$ is the mass of magnesium

$M_{o}$ is the mass of oxygen

$M_{z}$ is the mass of magnesium oxide

$425+ M_{o} = 600$

=> $M_{o} = 600 - 425$

=> $M_{o} = 175 g$

I need help if anyone will help plz

maksim [4K]

Answer:

Explanation:

If you look at the problem, and the coefficients (the little numbers on the bottom) you will see that on the reactant side you get a total of 11, you look over to the product side and you also get a total of 11.

B. is wrong because they’re are the same amounts

C.is wrong because they have the same amount of carbon

D. Now similar to B but slightly different the matter is the reactant side I’m pretty sure is equal to the amount on the product side.

If I had to take a strong guess though I would choose D just because the question is asking for the one that shows The law of conservation of mass. Pls make me brainlist

How does entropy change with pressure?

nydimaria [60]

The entropy will increase in pressure if you increase the pressure on the system the volume decrease the energies of the particles are in a smaller space so they are less spread out
