Not sure about P4S5, but CH4 is Methane, NF3 is Nitrogen trifluoride, and N2O is Nitrous oxide.
0.032 Ms = 3.2 × 10^4 s
<em>Step 1</em>. Convert the number to scientific notation.
0.032 = 3.2 × 10^(-2)
<em>Step 2</em>. Convert the measurement to base units.
3.2 × 10^(-2) Ms × (10^6 s/1 Ms) = 3.2 × 10^4 s
However, simple covalent compounds are generally named by using prefixes to indicate how many atoms of each element are shown in the formula. Also, the ending of the last (most negative) element is changed to -ide. The prefixes used are mono-, di-, tri-, tetra-, penta-, hexa-, and so forth.
The answer is D because it uses the electrical energy from the wall to create heat (Thermal) energy for the clothes
