I cannot see your question to help you... sorry
Yes, because CO2 is carbon dioxide, and carbon dioxide contains molecules.
Answer:
58.94 mL
Explanation:
V1 = 48.3 mL V2 = v mL
T1 = 22 degree celsius OR 295 k T2 = 87 degree celsius OR 360 k
We will use the gas equation:
PV = nRT
Since the Pressure (p) , number of moles (n) and the universal gas constant(R) are all constants in this given scenario,
we can say that
V / T = k , (where k is a constant)
Since this is the first case,
V1 / T1 = k --------------------(1)
For case 2:
Since we have the same constants, the equation will be the same
V / T = k (where k is the same constant from before)
V2 / T2 = k (Since this is the second case) ------------------(2)
From (1) and (2):
V1 / T1 = V2 / T2
Now, replacing the variables with the given values
48.3 / 295 = v / 360
v = 48.3*360 / 295
v = 58.94 mL
Therefore, the final volume of the gas is 58.94 mL
It would be probably most likely B
Answer:
%age Yield = 20.12 %
Solution:
The Balance Chemical Reaction is as follow,
Cl₂ + 3 F₂ → 2 ClF₃
According to Equation ,
114 g (3 mole) F₂ produces = 184.88 g (2 moles) of ClF₃
So,
19.2 g of F₂ will produce = X g of ClF₃
Solving for X,
X = (19.2 g × 184.88 g) ÷ 114 g
X = 31.13 g of ClF₃ (Theoretical Yield)
As we know,
%age Yield = (Actual Yield ÷ Theoretical Yield) × 100
%age Yield = (6.3 g ÷ 31.3 g) × 100
%age Yield = 20.12 %
