If a krypton atom has a mass of 84 and an iron atom has a mass of 56 and the distance between particles was the same, which atom
2 answers:
Explanation:
As it is known that density is defined as the mass present in per unit volume.
Mathematically, Density =
Since, density is directly proportional to mass. Hence, more is the mass of an object more will be its density.
Hence, mass of krypton is 84 whereas mass of iron is 56. This shows that mass of krypton is more than the mass of iron.
Therefore, density of krypton is more than the density of iron.

Answer:
0.0008 mole of HCl
Explanation:
From the balanced equation between HCl and NaOH:
1 mole of acid requires 1 mole of base for neutralization.
mole = molarity x volume
mole of NaOH = 0.02 x 0.04 = 0.0008 mole
mole HCl = 0.16 x 0.01 = 0.0016 mole
Since 1 mole of NaOH requires 1 mole of HCl for neutralization, it means that 0.0008 mole of NaOH will require 0.0008 mole of HCl. The remaining mole of HCl must have been neutralized by the antiacid:
0.0016 - 0.0008 = 0.0008 mole.
Therefore, 0.0008 mole of HCl must have been neutralized by the antiacid.
