Answer:
I think it was a huge fish. umm not sure
Explanation:
Answer:
Partial pressure of 
in the gas was 733 torr and mass of 
in the sample was 2.12 g.
Explanation:
a) Total pressure of gas = (partial pressure of water vapour)+(partial pressure of )
Here partial pressure of water vapour is 21 torr and total pressure of gas is 754 torr.
So, partial pressure of = (total pressure of gas)-(partial pressure of water vapour) = (754 torr) - (21 torr) = 733 torr
b) Lets assume that behaves ideally. Hence-
PV=nRT
where P is pressure of , V is volume of , n is number of moles of , R is gas constant and T is temperature in kelvin
here P = 733 torr = 
= 0.9646 atm
V = 0.65 L, R = 0.082 L.atm/(mol.K), T=(273+22)K = 295 K
So, 
= 
= 0.0259 moles
As 3 moles of are produced from 2 moles of therefore 0.0259 moles of are produced from 
moles or 0.0173 moles of .
Molar mass of = 122.55 g
So mass of in sample = 
= 2.12 g
Answer: B. Metal
Explanation: The catalyst used in the converter is mostly a precious metal such as platinum, palladium and rhodium Hope This Helped (=^･-･^=)
Answer: 3.37x10^23 atoms
Explanation:
1mole of Fe contains 6.02x10^23 atoms.
0.56mol of Fe will contain = 0.56x6.02x10^23 = 3.37x10^23 atoms
Answer:
1.06 M
Explanation:
200.12/36.46= ans./5.2
grams/atomic mass = ans./volume (L)
