Answer:
D) Endothermic
Explanation:
An endothermic reaction absorbs heat. In this case, the wax absorbs the heat and it melts.
Also, I took the exam and I got it right.
Answer:
6moles of O2 will be produced
Explanation:
Step 1: write the correct and balance the equation
2KClO3 --------> 2KCl + 3O2
Step 2: find the mole
2 moles of KClO3 gives 3moles of O2
We are provided with 4 moles of KClO3,
Since 2 moles of KClO3 = 3 moles of O2
4 moles of KClO3 = x moles of O2
Cross multiply
2 = 3
4 = x
4 * 3 = 2 * x
12 = 2x
Divide both sides by 2 , to get the mole of O2
12/2 = 2x/ 2
6 = x
x = 6
The mole of O2 is 6 moles
Explanation:
At sea level, the atmospheric pressure would be a little over 100 kPa (one atmosphere or 760 mm Hg). If we climb to the top of Mount Everest (the highest mountain in the world at 29,029 feet or 8848 meters), the atmospheric pressure will drop to slightly over 30 kPa (about 0.30 atmospheres or 228 mm Hg).
