Answer:
Dependent on the element that reacted with carbon
Explanation:
Nuclear fusion is the combination of small atomic nuclei into larger ones usually accompanied with the release of a large amount of energy.
From the problem stated, carbon fuses with another atom. The combined atom would have more nuclear particles in terms of protons and neutrons than the combining atoms. This will eventually make it weigh more than carbon and the atom it combines with. The resulting weight will depend on the combining atoms eventually.
The available energy decreases as one moves upward in an energy pyramid.
<h3>Energy pyramid</h3>
The energy pyramid represents a model of how energy is transferred from one trophic level to another in ecosystems.
Energy is transferred from producers to primary consumers, from primary to secondary consumers, from secondary to tertiary consumers, and so on.
Only about 10% of the available energy in one trophic level is transferred to the next with the remaining 90% being lost as heat to the environment.
Thus, as one moves up the energy pyramid, the available energy decreases. This is why organisms at the higher end of the energy pyramid have to devise an efficient way of extracting energy from their foods.

#SPJ1
Answer:
B) Iron (c=0.45 J/g°C)
Explanation:
Given that:-
Heat gain by water = Heat lost by metal
Thus,
Where, negative sign signifies heat loss
Or,
For water:
Mass = 120 g
Initial temperature = 21.8 °C
Final temperature = 24.5 °C
Specific heat of water = 4.184 J/g°C
For metal:
Mass = 40.2 g
Initial temperature = 99.3 °C
Final temperature = 24.5 °C
Specific heat of metal = ?
So,
<u>This value corresponds to iron. Thus answer is B.</u>
Hello.
The answer is: D it produces hyrogen ions in a solution.
This is correct because when Arrhenius acid it turns into hydrogen ions.substance as an acid if it produces hydrogen ions H(+) or hydronium ions in water. A substance is classified as a base if it produces hydroxide ions OH(-) in water.
have a nice day
