There are billions of stars in the known universe. None of them seem to be as bright as the Sun. Which statement gives the best
gogolik [260]

Answer:

The answer is D. The Sun is the closest star to Earth and so it seems brighter than distant stars that have much greater absolute brightness.

Explanation: Stars like red super giants like beetleguise are way brighter and bigger than the sun, but the sun is closest to the earth. It is only in its main sequence stage but seems bright because of its short distance from the sun( 93 million miles).

4. Assuming the reaction below is at equilibrium, which of the following changes will drive the reaction to the left? C(s) + O2(
shepuryov [24]

Answer:

Increasing temperature

Explanation:

C(s) + O_2(g) \leftrightharpoons CO_2(g)

Enthalpy of the reaction = -393.5 kJ/mol

Negative sign implies that reaction is exothermic.

Effect of change in reaction condition is explained by Le chateliers principle.

According to Le chateliers principle, if the reaction conditions of a reversible reaction in a state of dynamic equilibirum is changed, the reaction will move in a direction to counteract the change.

1. Increasing the temperature

Forward reaction is exothermic that means temperature increases in forward direction. Backward reaction will be endothermic and so there is decrease in temperature in backward direction or in left direction.

On increasing temperature, reaction will be move in direction to counteract the increased temperature, therefore reaction will move in left direction.

2. Adding O2

If O2 is added, then reaction will move in a direction in which its get consumed. So, reaction will move in forward direction or in right direction.

3. Removing C (s)

Le Chatelier's principle does not apply on solids, so removal of C(s) does not affect the equilibrium.
