Answer:
16 cm
Explanation:
Because when you look at the ruler, it shows the length as 16 cm
Answer: Mass of
produced in this reaction was 6.56 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Mass or reactants = Mass of
+ mass of
= 16.00 + 64.80 = 80.80 g
Mass of products = mass of aqueous solution + mass of
+ = 74.24 + x g
Mass or reactants = Mass of products
80.80 g = 74.24 + x g
x = 6.56 g
Thus mass of
produced in this reaction was 6.56 grams
Answer:
Yes atoms can accept the electrons from another atom like
Chlorine accept electron from hydrogen.
Explanation:
Answer: 
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Thus in the reactants, there are 2 atoms of hydrogen and 2 atoms of iodine .Thus there has to be 2 atoms of hydrogen and 2 atoms of iodine in the product as well. Thus a coefficient of 2 is placed in front of HI.
The balanced chemical reaction is:

Answer:
The ration of molar concentration is "2.5".
Explanation:
The given values are:
Average density of salt water,
= 
Net pressure,
= 
Increase in pressure,
= 
Now,
The under water pressure will be:
= 
= 
= 
= 
hence,
The ratio will be:
= 
or,
= 
= 
=
