In a certain city, electricity costs .10 per k. w.h. what is the annual cost dor electricity to power a lamppost for 5 hours/day with a 100 watt incandescent light bulb

The annual cost is $18.25.

Step 1. years → days

1 yr × (365 days/1 yr) = 365 days

Step 2. days → hours.

365 days × (5 h/1 day) = 1825 h

Step 3. hours → watt-hours

1825 h × 100 W = 182 500 W·h

Step 4. watt-hours → kilowatt-hours

182 500 W·h × (1kW·h/1000 W·h) = 182.5 kW·h

Step 5. kilowatt-hours → dollars

182.5 kW·h × ($0.10/1 kW·h) = $18.25

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
