For numbers less than 0.1 such as 0.06, the zeros to the right of the decimal point but before the first nonzero digit show the decimal place of the first digit.
The number of significant figures in a measurement often show the degree of accuracy of the measurement. We ascertain the number of significant figures from the first non - zero digit in the figure.
Given the figure 0.06, there is only one significant figure present. The zeros to the right of the decimal point but before the first nonzero digit show the decimal place of the first digit.

If iron has a density of 7.87g/cm³ and a mass of 3.729g, then the volume of iron is 0.474cm³
HOW TO CALCULATE VOLUME:
- The volume of a substance can be calculated by dividing the mass by its density. That is;
Volume (mL) = mass (g) ÷ density (g/mL)
- The density of iron is given as 7.87g/cm³ while its mass is 3.729g of iron. Hence, the volume can be calculated as follows:
Volume = 3.729 ÷ 7.87
Volume = 0.474cm³
Therefore, the volume of iron is 0.474cm³

The arrangement of particles that make up an ionic compound would be an ionic lattice type of crystal arrangement. An ionic lattice type of structure will be formed due to many of the ionic bonds formed between the oppositely charged ions of the metal and nonmetal.
Answer:
P-block metals have classic metal characteristics like they are shiny, they are good conductors of heat and electricity, and they lose electrons easily. These metals have high melting points and readily react with nonmetals to form ionic compounds.
Explanation:
