[SO3]: The concentration increases.
c)
[SO2]:There is no change.
[O2]: There is no change.
[SO3]: There is no change
Explanation:
For an exothermic reaction, increase in temperature decreases the concentration of products and increases the concentration of reactants since increase in temperature shifts the equilibrium position to the left hand side.
Increase in pressure and decrease in volume will shift the equilibrium position towards the right hand side which means more SO3 in the system.
Catalyst increases the rate of forward and reverse reaction simultaneously hence at equilibrium, the concentration of reactants and products remain unchanged.
Answer:
1. conduction 5. heat from the air is absorbed by ice cubes is conduction 6. a hot horseshoe transfers heat to the tongs is conduction. 8. a bowl of oatmeal cools is convection 9. water is warmed over a fire is convection/radiation 10. a spoon gets warmer after sitting in a bowl of soup is conduction.
Explanation:
the last two i don't know sorry but i give u the answers to the others:)
Answer:
Based on the Modern Periodic table, there is an increase in the electropositivity of the atom down the group as well as increases across a period. On comparing the electropositivities of the mentioned oxides central atom, it is seen that Ca is most electropositive followed by Al, Si, C, P, and S is the least electropositive.
With the decrease in the electropositivity, there is an increase in the acidity of the oxides. Thus, the increasing order of the oxides from the least acidic to the most acidic is:
CaO > Al2O3 > SiO2 > CO2 > P2O5 > SO3. Hence, CaO is the least acidic and SO3 is the most acidic.
Answer:
B
Explanation:
Generally, when you dilute something, your goal is to thin your concentration. Even if you added a solute, if your goal is dilution, it will make the concentration decrease.
_2k + _F2—> _2KF
put a 2 before the K and before the KF and you’re all good. it needed to be balanced with the F2
