Answer: Imidogen
Explanation: I just looked it up.
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.
Answer:
Tthe value of
Explanation:
Initial moles of hydrogen peroxide = 1.75 mole
Volume of the container = 25 L
Concentration of a substance is calculated by:
So, concentration of hydrogen peroxide =
The given chemical equation follows:
Initially 0.07 M 0 0
At equilibrium
(0.07-2x) M 2x x
We are given:
Equilibrium moles of hydrogen peroxide = 1.20 mole
Equilibrium concentration of hydrogen peroxide =
Evaluating the value of 'x', we get:
(0.07-2x) M = 0.048 M
x = 0.011 M
So, the equilibrium concentrations of water vapors and oxygen gas are:
The expression of for the above reaction follows:
Putting values in above expression, we get:
Hence, the value of
