Calculate the enthalpy change per mole of oxygen consumed in the reaction:

1 answer:

6 0

Your question is asking for the heat of formation of UO3 per mole O2(g) consumed
You have to find the value of enthalpy of formation since the reaction is the standard heat of information. The value is -1223.8. This represents the amount of heat released when 1 mol of UO3 is formed. Now 1 mol of UO3 needs 3/2 moles of O2(g).
The equation will look like this
-1223.8kJoules / molUO3 x 2molO2 = -815.7 kJ
 3mol uO3 molO2 (g)

What is the distance if traveling 6.5 m/s for 25 seconds

Nesterboy [21]

Explanation:

In this problem, we are given a conversion factor.

$6.5 m=1s$

So, since we know this, we can simply multiply 25 by 6.5 to see what the distance will be.

25 * 6.5 = 162.5

So, the distance traveled for 25 seconds is 162.5 miles.
