Answer 1) : To rank the species according to the decreasing energy needed to raise the temperature of 10 g of the substance by 25 °C, the oder of energy needed is given below as per their specific heat.
Which requires more energy as per their specific heats;
- water 4.184
- aluminum 0.897
- cast iron 0.460
- Copper 0.385
- Silver 0.235
Answer 2)To rank items as equivalent, overlap them.
The average kinetic energy of the molecules after point D,
The average kinetic energy of the molecules from point B to point C,
The average kinetic energy of the molecules before point A.

Answer:
E° = -1.66 V
Explanation:
The standard reduction potential is also known as the standard electrode potentials and it tries to find the probability that an element will be reduced or undergo reduction.
From activation series online showing the standard reduction potentials for half cells, the standard reduction potential of Al3+ (aq) + 3e- -> Al(s) is;
E° = -1.66 V
Answer:
the large object moving quickly because the more the mas the more kenetic energy
Answer:
