Answer:
All of the physical and biological factors in it's environment, I think this is the answer, but I might be wrong.
Explanation:
I learned it in my school's Science class
Question:
A student weighed an empty graduated cylinder. It weighed 35.86 g. She then carefully added water to the graduated cylinder until it reached the 7.5 mL mark. When she weighed the graduated cylinder again, this time with the 7.5 mL of water in it, it weighed 43.18 g. What was this student's experimental density of water?
Answer:
0.976 g/mL
Explanation:
Weight of empty cylinder = 35.86g
Volume of water = 7.5mL
Weight of cylinder + water = 43.18g
Experimental density = ?
Density of water = Mass of water / volume of water
Mass of water = (Weight of cylinder + water) - Weight of empty cylinder
Mass of water = 43.18 - 35.86 = 7.32g
Density = 7.32 / 7.5 = 0.976 g/mL
I think it's 2:1 or 2:1:4. I mostly think it's 2:1 though. (:
Explanation:
The reaction between calcium hydroxide and nitric acid is as follows.

Number of reactant atoms are as follows.
Number of product atoms are as follows.
To balance the given chemical equation, multiply
by 2 on reactant side and multiply
by 2 on the product side.
Therefore, the balanced chemical equation will be as follows.

Answer:
, product favoured
Explanation:
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.
Net ionic equation : In the net ionic equations, we do not include the spectator ions in the equations.
When hydrochloric acid react with potassium cyanide, then it gives potassium chloride and hydrocyanic acid as products.
The complete ionic equation will be:
The net ionic equation will not contain spectator ions which are
and
:

The reaction is product favoured.
