Answer:
We can just use the formula for the volume of sphere which is 4/3 PI R cubed R is the radius. So if you have a balloon that's a sphere.
Explanation:
Answer:
The area of the block is 150 cm
Explanation:
Answer:
1.44mole of CO
Explanation:
The reaction equation is given as:
5C + 2SO₂ → CS₂ + 4CO
We check to see if the expression is balanced and it is so;
Now;
Given;
1.8mole of C reacted; how many moles of CO are produced;
From the balanced reaction equation:
5 mole of C is expected to produce 4 mole of CO
1.8 mole of C will then produce 
= 1.44mole of CO
Answer:
P2 = 0.935 atm
Explanation:
initial conditions:
∴ V1 = 3.41 L
∴ T1 = - 91.5 °C + 273 = 181.5 K
∴ P1 = 3990 torr * ( atm / 760 torr ) = 5.25 atm
∴ R = 0.082 atm.L / K.mol
⇒ n = P1V1 / RT1 = ((5.25 atm)*(3.41 L)) / ((0.082 atm.L/K.mol)*(181.5 K))
⇒ n = 1.107 mol
final conditions:
∴ V2 = 3.3 L
∴ T2 = - 239 °C = 34 K
∴ n = 1.107 mol
⇒ P2 = nRT2 / V2
⇒ P2 = ((1.107 mol)*(0.082 atm.L/K.mol)*(34 K)) / 3.3 L
⇒ P2 = 0.935 atm
