Answer:
Calcium carbonate
Explanation:
Ionic compounds that tend to have one or more polyatomic ions are the ones that tend to exhibit both ionic and covalent bonding. The only one that meets this is calcium carbonate.
The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder.
Answer:
48.03grams
Explanation:
Density of a substance is calculated as follows:
Density (g/cm³) = mass (g) / volume (cm³)
Based on the information given in this particular question:
Density of lead (Pb) = 11.3 g/cm³
Volume of lead (Pb) = 4.25 cm³
Density = m/V
11.3 = mass/4.25
Mass = 48.025
= 48.03grams.
