Answer:

5.733 days

Explanation:

To convert from minuets to days we must first convert minuets to hours. To do this we divide by 60 since there are 60 minuets in one hour.

8255 min ÷ 60 = 137.6 hr

Now that we have the amount of hours we can convert to days by dividing by 24 since there are 24 hours in one day.

137.6 hr ÷ 24 = 5.733 days

What happens to the reaction c2h6 + 137 kj when the temperature of the reaction is increased?
Solnce55 [7]

The answer is it shifts right. This could be explained by Le Chatelier's principle. It states that that when a system experiences a commotion (such as absorption, temperature, or heaviness variations), it will answer to reinstate a new equilibrium state. This just means that if there is an energy added, the reaction is trying to remove it again by going to the right.

I need to know all the answers for this homework!!!!
maw [93]

1. 100 C

2. Point B to C is the ices heat capacity

3. During the points D to E the bonds of the water molecules build up enough kinetic energy to break their intermolecular bonds (not intra), which can lead to gas.

4. Between points D and E the energy is being released the energy required is equivalent along the line.

5. Between point E and D the water is converting to water (condensation)

6. Energy is being released 2260 j/g

7. Yes, but only under extreme volumetric pressures

8. D and E or B and C

9. Freezing (the water is also becoming less dense)

10. Melting or if water already, absorbtion of energy

11. released.
