I think that is the answer
Answer:b
Explanation: the particles will soon dissolve which means that the particles are changing but the volume is staying the same and the concentration is changing
Answer:
Option c → 8:1
Explanation:
This is the reaction:
C₅H₁₂ + 8O₂ → 10CO₂ + 6H₂O
1 mol of pentane needs 8 moles of oxygen to be combusted and this combustion produces 10 mol of carbon dioxide and 6 moles of water.
To determine the ratio, look the stoichiometry.
For every 8 moles of oxygen, I need 1 mole of pentane gas.
Electronic configuration is given by
- 1s orbital is filled
- 2s orbital is unfilled
So
Answer:
As you go down a group on the periodic table, you get more electron shells and therefore a larger atomic radius.
