Explanation:
A) Magnesium chloride -Magnesium chloride is the name for the chemical compound with the formula MgCl₂ and its various hydrates MgCl₂ₓ. Anhydrous MgCl₂ contains 25.5% elemental magnesium by mass. These salts are typical ionic halides, being highly soluble in water. The hydrated magnesium chloride can be extracted from brine or sea water.
Formula: MgCl2
Molar mass: 95.211 g/mol
IUPAC ID: Magnesium dichloride
Melting point: 714 °C
Boiling point: 1,412 °C
Soluble in: Water
B)calcium oxide -Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature.
Formula: CaO
IUPAC ID: Oxocalcium
Molar mass: 56.0774 g/mol
Melting point: 2,572 °C
Density: 3.34 g/cm³
Soluble in: Water, Glycerol
c)Nitrogen molecule -Molecular nitrogen (N2) is a very common chemical compound in which two nitrogen atoms are tightly bound together. Molecular nitrogen is a colorless, odorless, tasteless, and inert gas at normal temperatures and pressures. About 78% of Earth's atmosphere is nitrogen.
d)water -Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients.
Density: 997 kg/m³
Boiling point: 100 °C
Molar mass: 18.01528 g/mol
Formula: H2O
Melting point: 0 °C
IUPAC ID: Oxidane, Water
E)hydrogen chloride -The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colourless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry.
Formula: HCl
IUPAC ID: Hydrogen chloride
Boiling point: -85.05 °C
Density: 1.49 kg/m³
Molar mass: 36.46 g/mol
Soluble in: Water
