Question 22 4 pts If all the
batteries currently present in the world were fully charged and
connected to supply the world's energy, how long could we run the
world on this system? Less than one hour About one day A few weeks
About one month More than one month Flag this Question Question 23
4 pts What is the importance of batteries in using renewable energy
such as solar and wind power? Batteries are very energy dense.
Batteries provide energy even when it's dark and the wind is not
blowing. Batteries can be charged when energy is abundant and
discharged when energy is not. Batteries can keep electricity
flowing even when a cloud passes over head and reduces electricity
production from solar panels. Batteries last forever (or at least a
long time). Flag this Question Question 24 4 pts Why do ions form?
The universe needs a balance of positive and negative charges.
Atoms gain or lose electrons to obtain electron arrangements where
the outer shell is like the closest (on the Periodic Table) noble
gas. Ions form when electron sharing is not possible. Ionic
compounds are the only kinds of compounds that can dissolve in
water.
