<h2> Interconversion of energy.</h2>
Explanation:
- Carbon moves from plants and animals to soils in the form of cycle.
- When we take in oxygen we release carbon dioxide gas
into the atmosphere. - Animals and plants give carbon dioxide gas through the process called respiration and transpiration.
- From fossil fuels carbon moves in the atmosphere.
- The fuels like wood or coal when burned releases carbon dioxide into the atmosphere.
- The Matter is conserved in the carbon cycle as carbon absorbs energy and then it releases the same amount of energy.
- Carbon changes from one form to another, but the total amount of carbon remains the same.
Answer:
2
Explanation:
symbol of postassium is k and there is no symbol k. so i guess no2
Answer:
The answer is D all of the above
Explanation:
Answer:
ΔH = -976.5 kJ
Explanation:
For the reaction given, there are 2 moles of benzene (C6H6). The heat of this reaction is -6278 kJ, which means that the combustion of 2 moles of benzene will lose 6278 kJ of heat. It is an exothermic reaction.
The value of ΔH, the enthalpy, is a way of measurement of the heat, and it depends on the quantity of the matter (number of moles).
So, 24.3 g of benzene has :
n = mass/ molar mass
n = 24.3/78.11
n = 0.311 moles
2 moles ------------ -6278 kJ
0.311 moles ----------- x
By a simple direct three rule:
2x = -1953.08
x = -976.5 kJ
