See Explanation
Explanation:
Elements in group fourteen are mostly known to form compounds in which there are four electron domains leading to a tetrahedral electron domain geometry.
However, the presence of lone pairs affects the shape of the molecule. SnCl3− has four electron domains, three of them are bond pairs while one is a lone pair. The shape of the molecule is based on a tetrahedron, however the observed geometry is trigonal pyramidal due to the presence of the lone pair. Its bond angle is now less than the predicted 109 degrees.
Moles = 4.03 x 10^21

6.02 x 10^23
= 6.69 x 10^-3 moles.

Answer:
Option 5. 179L
Explanation:
The reaction is:
2 HCl + Na₂CO₃ → 2NaCl + H₂O + CO₂
The amount of collected CO₂ is 8 moles.
We apply the Ideal Gases Law at STP
STP are 1 atm of pressure and 273K of T°
P . V = n . R . T
1atm . V = 8 mol .0.082L.atm/mol.K . 273K
V = (8 mol .0.082L.atm/mol.K . 273K) / 1 atm = 179 L
Answer: 1.) renewable resources can be replenished as fast as they are used. Nonrenewable resources are unable to be replaced at the same rate at which they are used. 2.) nonrenewable energy sources will eventually run out, leaving people to figure out how to continue running their cars, homes, and busines. They must find alternative sources of energy. Since renewable energy resources that will never run out, it is a great option.
