I) Interpret the chemical equation in terms of quantitative aspect. C3H8(g) + 5O2(g)->3CO2(g) + 4H2O(1/ce)

ii) Then, interpret it in terms of qualitative aspect. ​

Quantitative aspect: one mole of propane reacts with five moles of oxygen ( combustion ) to produce three moles of carbon dioxide and four moles of water.

Qualitative aspect: A colourless gas ( propane ) burns with a blue flame ( combination ) to form a colourless gas that turns lime water milky and drops of colourless liquid that turn anhydrous copper (ii) oxide from blue to white.

a. stateTaxRate  - A good variable name because it represents what it holds, the state sales tax rate, without being too wordy. Also correctly capitalized in camelcase.

b. txRt  - A bad variable name because while short and simple, it is too hard to understand what the variable represents.

c. t  - A very bad variable name if you plan on using the variable often. Far too short and you will forget what it represents and is needed for.

d. stateSalesTaxRateValue  - A bad variable name because it is just too wordy. Cutting it down to A's variable name is much more reasonable

e. state tax rate  - A bad variable name and probably invalid because it has spaces in the name.

f. taxRate  - A good variable name if there are no other tax calculations other than state tax rate. Otherwise you would confuse state vs local tax rate or something, making it a bad variable name.

g. 1TaxRate  - A bad variable name because the number 1 has no reason being in the variable name. It doesn't add anything to the name.

h. moneyCharged - A bad variable name because it is not specific enough in explaining why the money is being charged and what for.
