Answer: D
Explanation: I got it wrong on my test :( and got this answer as correct.
Answer:
hydrogen and oxygen to form water
Answer:
B) The metal temperature changed more than the water temperature did, but the metal lost
the same amount of thermal energy as the water gained.
Explanation:
Heat capacity or thermal capacity is defined as the amount of heat required by a given mass of a material to raise its temperature by one unit which means that the heat capacity of the water, that is the quantity of heat required to cause a rise from 22°C to 35°C that is a rise of 13°C is the quantity of heat that caused the drop in temperature of the metal from 100°C to 35°C a change of 65°C
The water has more capacity to absorb heat or a higher heat capacity than the metal
However, the first law of thermodynamics states that energy is neither created nor destroyed, but it changes from one form to another. In this case, the thermal energy lost by the metal is the same as the thermal or heat energy gained by the water
The kind of reaction involving the transfer of electrons or hydrogen away from a molecule is called oxidation.
In the same vein, the molecule that receives the electron or the hydrogen atom is said to be reduced. This means that oxidation cannot exist in isolation without reduction.
In other words, oxidation is defined as:
- Loss of electrons
- Loss of hydrogen atoms
- Gain of oxygen atoms
- Gain in oxidation number
While reduction is defined as:
- Gain of electrons
- Gain of hydrogen atom
- Loss of oxygen atom
- Reduction in oxidation number

Answer:
when a substance is heated it gains thermal energy. Therefore its particles move faster and its temperature rises. when a substance is cool it loses thermal energy which causes its particles to move more slowly and its temperature to drop
