Answer:
The temperature is 30,92K
Explanation:
We use the formula PV=nRT. We convert the unit of pressure in kPa into atm.
101,325kPa----1atm
121kPa-------x=(121,3kPax 1 atm)/101,325kPa=1, 2 atm
PV=nRT---->T= (PV)/(RT)
T=(1,2 atm x 3L)/(1,42 mol x 0,082 l atm/K mol )= 30, 91721058 K
The Group 1 elements, which include lithium (Li), sodium<span> (</span>Na) and potassium (K<span>) are also known as the alkali metals. They all </span>have<span> one electron in the outer shell and so they </span>have similar properties<span>.</span>
Answer:
18
Explanation:
You add the two numbers on the bottom left (8 and 32) and then subtract the number On the bottom middle right (22) from it (40-22=18) and then the answer to that gives you the answer of how much water is produced.
hope that helped :)
Answer:
4.45 atm
Explanation:
Applying,
PV = P'V'............ Equation 1
Where P = Initial pressure of the container, V = Initial volume of the container, P' = Final pressure of the container, V' = Final volume of the container.
make P the subject of the equation
P = P'V'/V........... Equation 2
From the question,
Given: V = 55.2 L, P' = 8.53 atm, V' = 28.8 L
Substitute these values into equation 2
P = (8.53×28.8)/55.2
P = 4.45 atm
