Ammonia is the most basic and has the highest OH- concentration since it has the highest pH.
Explanation:
It is given that two loads have 0.75 Ampere current each. And, they contain 2500 milli ampere per hour Ni-Cd battery.
As both the loads are connected in parallel. Hence, total current will be calculated as follows.
I =
= 0.75 A + 0.75 A
= 1.5 A
=
= 1500 mA
Relation between time and capacity of battery is as follows.
Capacity = Current × time (in hour)
therefore, time =
=
= 1.667 hr
Thus, we can conclude that the battery provide power to the load up to 1.667 hours.
A caption is a positively charged ion. They are formed when an ion loses one or more electrons. Typical it is the loss Of their valence electrons.
It should be option (A) because conduction is the transfer of heat energy from one place to another by vibrations/motion of the molecules. I hoped I helped.
