Answer:
It would take 3.64 hours to travel.
Explanation:
200km with 55 per hour.
200 divided by 55 would equal 3.64.
I am dividing because to solve time would be distance/rate.
I hope this helps! :)
I think the correct answer 3. A solution is a type of mixture having a uniform composition where the components can't be seen separately and all components are in the same state. It is considered as a homogeneous mixture where at any point the properties and the concentration of the solution would have the same value.
The outer electron of atom B has moved to a higher energy state because (5s1 compared to 3s1. 5 is greater than 3). Therefore, your answer is B.
Answer:
The ratios of mole O2 to mole KClO3 are: 3/2, 1.5/1,1/2
Explanation:
The 3 possible equation of reaction for the decomposition of KClO3 are:
2KClO3 ==> 2KCl + 3O2
KClO3 ==> KCl + 1.5O2
2KClO3 ==> 2KClO2 + O2
When potassium chlorate (KClO3) is heated in the presence of manganese dioxide catalyst, it decomposes to form potassium chloride and oxygen gas.
