When an atom combines chemically with another atom, it either gains, loses, or shares ELECTRONS.
Answer:
Warm or hot air particles have more energy than that of cool air. As a result they move faster than cool air particles. Since sound propogation involves movement or vibration of particles, sound travels faster in warm air
Hope this helps!
Ngl, there is no picture.
The given thermochemical equation is:
Δ
Mass of CO given = 24.0 g
Moles of CO = 
Finding out the heat released to the surroundings when 24.0 g CO:

Therefore, 207 kJ of heat is released to the surroundings when 24.0 g CO reacts completely.
