Since both sides have to be equal to each other, subtracting the left side from the right side will leave you with the other reactant.

On the right side, you have 1 sodium, 2 carbon, 5 hydrogen, and 3 oxygen.

If you take away 1 sodium, 1 oxygen, and 1 hydrogen you are left with 2 carbon, 4 hydrogen, and 2 oxygen.

This is written as CH3COOH
AKA Acetic Acid

Describe how chemical substances are used based on their physical properties?
Lilit [14]
The answer is
Physical properties: Properties that do not change the chemical nature of matter
Chemical properties: Properties that do change tha chemical nature of matter

Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples. Note that measuring each of these properties will not alter the basic nature of the substance.

Examples of chemical properties are: heat of combustion, reactivity with water, PH, and electromotive force.

C. CaCl2 can be melted to produce calcium metal and give off chlorine gas. The equation for this
galben [10]

Answer:

Total gram of Ca = 99.26 g

Explanation:

Given:

Mass of CaCl₂ = 277.45 g

Find:

Mass of Ca

Computation:

Ca = 40 g/mol

Cl₂ = 2 (35.5) g/mol = 71 g/mol

Total CaCl₂ = 111 g/mol

Total gram of Ca = [40 / 111] 277.45 g

Total gram of Ca = 99.26 g
