From the equation, 32 equiv dixoygen gas evolve from 1 equiv chlorate.
You started with 6 equiv chlorate, and thus 9 equiv dioxygen gas are evolved. This is a common undergrad experiment. I think you need to add some sort of manganese oxide catalyst.
Answer:
1.25 moles of HF
Explanation:
1 mole = 20.0 grams of HF
So, to calculate mass of 25.0 grams
=25.0*1/20.0
=1.25 moles
Answer:
<em>0.531 moles</em> of CO₂ are formed.
Explanation:
Given data:
Number of moles of CO = 0.531 mol
Number of moles of CO₂ formed = ?
Amount of oxygen = excess
Solution:
Chemical equation:
2CO + O₂ → 2CO₂
Now we will compare the moles of CO with CO₂.
CO : CO₂
2 : 2
0.531 : 0.531
Thus, 0.531 moles of CO₂ are formed.
Answer:
B
Explanation:
The student is not able to move the box in D --> 55N, 0N. Since the net force is 0, it means that no force is being applied. So you will choose answer B from your options.
Hope this helps, thank you !!
Answer:
Both are different.
Explanation:
Both rocks are different from one another because both formed from different types of rocks. Rock A was formed from small pieces of rock while on the other hand, Rock B was formed from liquid rock so they both have different sources of rocks from which they were formed. Forming at the same time does not show that they are similar to each other, it is their source which decides that they are similar or different.
