Sand is usually hot from the sun. It is hot because of the sun. if the sand were to be wet then it would take longer to change.
Answer:
force exerted on the ball
Explanation:
Answer: has pH more than 7
Explanation:
<u>Answer:</u>
<u>For 1:</u> The minimum standard electrode potential at cathode is -0.03 V
<u>For 2:</u> The maximum standard electrode potential at cathode is 1.63 V
<u>Explanation:</u>
To calculate the
of the reaction, we use the equation:

We are given:
= Standard electrode potential of the cell = 0.80 V
To make the standard reduction potential at the cathode minimum, we take the standard reduction potential at anode as (0.83 V)
Putting values in above equation, we get:

Hence, the minimum standard electrode potential at cathode is -0.03 V
To make the standard reduction potential at the cathode maximum, we take the standard reduction potential at anode as (-0.83 V)
Putting values in above equation, we get:

Hence, the maximum standard electrode potential at cathode is 1.63 V
a hearing aid.
it doesn't get in contact with fluids (like contact lenses) and doesn't get implanted, so it got not much to do with the immune system
