Heat travels from hot to cold in order to balance out the temperature. Thus, the heat transfer goes from the hot water to the finger.
If the water was hot enough, it would transfer too much heat, and the finger would get burned.
12/12= 1 mol
this is because: amount of moles=mass/relative formula mass and the relative formula mass of carbon is 12
Answer:
Answer is A
Explanation:
I dont have an explanation
Answer:
A. maintain electrical neutrality in the half-cells via migration of ions
Explanation:
Salt bridge -
For an electrochemical reaction , involving an anode and a cathode , both the electrodes are connect via a salt bridge to complete the circuit for the reaction .
One of the very important use of a salt bridge is to maintain the electrical neutrality of the respective half cells , which is achieved by the movement of ions .
Hence , from the given options , the correct option is ( a ) .
Answer:
Krypton gain
strontium lose
xenon neither gain or lose
