Question

entering chemical expressions
to enter chemical formulas, equations, and expressions using correct formatting, use the menu tabs above the answer space or use the keyboard shortcuts. for example, to enter the subscript 2 in h₂o, go to the templates menu and select the subscript template (x_b).
when you enter your answer, keep in mind that the order of the elements in each chemical formula is important. enter elements in the order you are taught in your chemistry textbook.
part a
enter the molecular formula for butane, c₄h₁₀.
express your answer as a chemical formula.
a chemical reaction does not occur for this question.

Explanation:

Step1: Identify the elements and their counts

Butane has 4 carbon (C) atoms and 10 hydrogen (H) atoms.

Step2: Write the chemical formula

The standard way to write the molecular formula is to write the symbol of each element followed by the number of its atoms as a sub - script. So the formula is $C_{4}H_{10}$.

Answer:

$C_{4}H_{10}$
