Equation: MgOH2 (s) --> MgO (s) + H2O (g)
And it's already balanced.
I had chemistry this semester too.
Answer:
It should be silicon... I even googled it to see if I was correct and that’s what it says so can someone figure out why silicon is not an answer
Explanation:
Answer: A cold compress used by athletes is an endothermic reaction.
Explanation:
A pack of cold compress used by athletes contains water that holds another bag or tube inside it which is filled with ammonium nitrate fertilizer.
So, on hitting the cold compress the tube breaks down due to which fertilizer gets mixed with water. This mixture absorbs the heat when placed on the area of body having pain, strain or bump.
As a result, we tend to feel cold at the affected area of our body.
Thus, we can conclude that a cold compress used by athletes is an endothermic reaction.
Answer:
Applied Chemistry is the scientific field for understanding basic chemical properties of materials and for producing new materials with well-controlled functions. (:
Answer: 65.28 g of
will be produced from 34.6 g of Al.
Explanation:
To calculate the moles :
The balanced chemical reaction is
According to stoichiometry :
4 moles of
produce = 2 moles of
Thus 1.28 moles of
produce=
of
Mass of
=
Thus 65.28 g of
will be produced from 34.6 g of Al.
