Explanation:
It is given that,
The time period of artificial satellite in a circular orbit of radius R is T. The relation between the time period and the radius is given by :

The radius of the orbit in which time period is 8T is R'. So, the relation is given by :



So, the radius of the orbit in which time period is 8T is 4R. Hence, this is the required solution.
Answer:
i) Dilute hydrochloric acid will react with Ammonia to form ammonia salt.
ii) dilute hydrochloric acid will react with soduim hydroxide to form sodium chloride and water
iii) dilute hydrochloric acid will react with calcuim carbonate to form Calcium chloride, Carbon dioxide and water.
Explanation:
CHEMICAL EQUATIONS :
I) HCL + NH3 = NH4Cl
ii) HCL+ NaOH = NaCl + H2O
iii) HCL + CaCo = CaCl2 + CO2 + H2O

Answer : The number of moles of
produced are, 0.66 mole.
Explanation : Given,
Given moles of
= 0.44 mole
The given balanced chemical reaction is,

From the given balanced chemical reaction, we conclude that
As, 4 moles of
react to give 6 moles of 
So, 0.44 moles of
react to give
moles of 
Therefore, the number of moles of
produced are, 0.66 mole.
