Answer:
1.4200 g
Explanation:
The chlorine gas has a molecular formula Cl2. In table periodic, the molar mass of one atom of chlorine is 35.5 g/mol, so the molar mass of Cl2 is 71 g/mol.
Molar mass, mass and number of moles are related by the equation below:
Where n is the number of moles, m is the mass, and MM is the molar mass of the compound.
So, for 0.0200 moles of Cl2 produced:
m = 71x0.0200
m = 1.4200
Answer:
The volume of sample at STP is = 41.22 ml
Explanation:
Given data
= 0.9 atm
= 50 ml
= 298 K
At STP
= 1 atm
= 273 K
From ideal gas equation
= 41.22 ml
Therefore the volume of sample at STP is = 41.22 ml
Answer:
The initial temperature of the ... What is the specific heat capacity of silver metal if 55.00 g of the metal.
Explanation:
Answer:
Honestly, while Hydrogen appears to be in group 1, it really isn't. It is unique, and has no characteristics similar to others, especially to the alkali metals in group 1 and halogens in group 17.
Hydrogen only shares one thing with alkali metals. It has one electron in the outermost shell, and has a valency of one. As far as halogens go, Hydrogen is a reducing agent, and halogens are known for being oxidizing agents.
So, I can say that more research needs to be done on Hydrogen. In the meantime, it is quite unique. Thanks!
