1.4mL
Explanation:
Given parameters:
Mass of object = 3.5g
density = 2.5g/mL
Unknown:
Volume of the object = ?
Solution:
Density is the mass per unit volume of a body. It is an intensive property that is the same for the same substances.
Density =
since the volume is unknown; we make it the subject of the formula;
Volume =
Volume =
Volume of the object = 1.4mL

Answer:
Carbon is the basic compound for making of molecules in biological systems. IN growth medium, carbon sources are added to provide energy.
Explanation:
Without carbon, there would be no life on earth. Carbon molecules have the ability to form bonds that are stable with a vast number of molecules. It can also form bonds with itself. The proteins, amino acids, DNA, RNA, lipids all contain carbon molecules. Hence, it serves as the basic compound for making molecules of life. In the growth culture media, Carbon is added in the form of carbohydrates like glucose or glutamine as it provides main source of energy.

Synthesis Reaction
Answer:
Water has strong hydrogen bond dipole-dipole intermolecular forces that give water a high surface tension and a high heat of vaporization and that make it a strong solvent.
Explanation:
Balanced it is 2P2O3 -> 4P + 3O2
