Question

write the formulas and name for each of the following compounds: (formulas with subscripts should be entered as regular text, i.e., h₂o should be entered as \h2o\) (a) name is , formula is etextbook and media

Explanation:

Step1: Count the number of each atom

There is 1 carbon (C) atom and 4 bromine (Br) atoms.

Step2: Name the compound

For binary covalent compounds, we use prefixes. The prefix for 1 is "mono -" (but we usually omit it for the first element in some common cases like here), and for 4 is "tetra -". The second element ends with "-ide". So it is carbon tetrabromide.

Step3: Write the formula

Based on the number of atoms, the formula is CBr4.

Answer:

Name is carbon tetrabromide, formula is CBr4.
