Explanation:
F = k.m1.m2/r²
m1 and m2: masses of objects
r: distance between the objects
k: a constant
Answer:
Calcium Nitrate is made up of three different elements and contains a total of nine atoms. This compound's formula is Ca(NO3)2. There is one calcium atom, two nitrogen atoms, and there are six oxygen atoms in calcium nitrate
No, the formation of dew is condensation, which is a physical change.
Explanation:
Tollens' reagent is prepared by using two-step process : -
Step 1:
Silver oxide is formed by mixing aqueous silver nitrate with base like sodium hydroxide. The reaction is shown below as:
![AgNO_3 + NaOH &\rightarrow AgOH + NHO_3 \nonumber \\ 2AgOH &\rightarrow Ag_2O + H_2O](https://tex.z-dn.net/?f=AgNO_3%20%2B%20NaOH%20%26%5Crightarrow%20AgOH%20%2B%20NHO_3%20%5Cnonumber%20%5C%5C%202AgOH%20%26%5Crightarrow%20Ag_2O%20%2B%20H_2O)
Step 2
Ammonia solution is drop-wise added until all the silver oxide dissolves to form the reagent. The reaction is shown below as:
![Ag_2O + 4NH_3 + H_2O \rightarrow 2Ag(NH_3)_2^+ + 2OH^-](https://tex.z-dn.net/?f=Ag_2O%20%2B%204NH_3%20%2B%20H_2O%20%5Crightarrow%202Ag%28NH_3%29_2%5E%2B%20%2B%202OH%5E-)
Answer:
0.5
Explanation:
1 mole of ammonium nitrate contains 2 moles of nirogen
1 mole of nitrogen converts to 0.5 moles of ammonium nitrate
the conversation factor is 0.5
