For a rapidly growing population is characterized by an increase in the number of young individuals, birth rates increased in comparison with mortality, and the age structure of the population gets the reproductive type In other words there is superiority of juveniles on the elderly and the relative decrease in mortality.
Explanation:
The given data is:
The mass% of a solution is 7.
Mass of solution =450g
The mass of salt required can be calculated as shown below:
Substitute the given values in this formula to get the mass of solute that is salt:
Mass of salt =31.5g
Mass of solvent that is water = 450g-31.5g=418.5g
Answer: KI, LiBr, MgS,GaN
Explanation:
Ionic sizes are the deciding factor in lattice energy. The smaller the ion, the higher the lattice energy. Since K+> Li+ and I- is larger than Br-, LiBr will have a higher lattice energy. The size of the sulphide ion is much smaller than the nitride ion but the Gallium is much smaller due to lanthanide contraction hence the answer.
