2 is your answer hope you get it right
Answer:
A
Explanation:
In a galvanic cell, energy is produced by spontaneous chemical processes.
The cathode and anode of this cell will depend on the relative position of the two metals in the electrochemical series.
Aluminium is higher in the electrochemical series so aluminium will be the anode. Silver is lower in the electrochemical series so silver will be the cathode.
Recall that oxidation (electron loss) occurs at the anode while reduction (electron gain) occurs at the cathode.
Answer:
Photons
Explanation:
A hot object emits photons of various energies, which propagate outwards from the object. When they hit another object, the photons can be absorbed, giving up their energy to the second object. This causes the atoms/molecules etc. to giggle around, rotate, vibrate etc., with the result that the second object heats up.
When we convert the given mass in grams and volume in liters to m/v percent, we recall that m/v percent is expressed as grams/100 milliliters. In this case the expression becomes (50 grams/ 2500 L)*(0.1L/100ml), that is equal to 0.002 grams/ 100 mL. Hence the the concentration is equal to 0.2 m/v percent.
Answer:
All of the above
Explanation:
Panthers, pumas, and mountain lions are all the same animal. Just different names. So, all of these would be correct.
