A6.34l sample of hydrogen gas exerts a pressure of 1.52 atm at 298k. what temperature would be required for it to have a volume of 4.98l and a pressure of 0.720 atm?

There is a temperature of 111 K required.

Explanation:

Step 1: Data given

Volume of hydrogen gas = 6.34 L

Pressure = 1.52 atm at 298 K

The volume of the gas at a pressure of 0.720 atm is 4.98 L

Step 2:

(P1*V1)/T1 = (P2*V2)/T2

⇒ with P1 = the pressure of the hydrogen gas = 1.52 atm

⇒ with V1 = the volume of the hydrogen gas = 6.34 L

⇒ with T1 = the temperature of the hydrogen gas = 298 K

⇒ with P2 = the changed pressure of the gas = 0.720 atm

⇒ with V2 = the changed volume of the gas = 4.98 L

⇒ with T2= the temperature of the gas at 0.720 atm and 4.98L

(1.52*6.34)/298 = (0.720*4.98)/T2

0.0323 = 3.5856/T2

T2 = 110.88 K ≈111K

There is a temperature of 111 K required.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
