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
Answer:
1.20 L = 1200 mL
Explanation:
P1V1/T1 = P2V2/T2
V2 = P1*V1*T2/(T1*P2)
V1 = 700ml =0.700 L
P1 = 106.6 kPa
T1 = 7+273.15 = 280.15 K
T2 = 27 + 273.15 = 300.15 K
P2 = 66.6 kPa
V2 = 106.6*0.700*300.15/(280.15*66.6)= 1.20 L=1200 mL
I would say B.
Explanation: Peer review improves the quality of research papers.
Answer:
The general electronic configuration of the element present in the 13th group of the periodic table is . Therefore, the number of valence electrons of the group 13this 3. Also, the metalloid element which is present in group 13th is boron. Hence the metalloid which has 3 valance electrons is boron.
