A process called respiration. This process is carried out in organelles in the cell<span> called the Mitochondria.</span>
B ase from the reaction <span>cacn2 3 h2o → caco3 2 nh3, for every 1 mole of caco3 produced there 2 moles of nh3 being produced. to solved this, we must first convert the caco3 to moles.
mass nh3 = 187 g caco3 (1 mol caco3 / 100 g caco3 ) ( 2 mol nh3 / 1 mol caco3) ( 17 g nh3 / 1 mol nh3)
mass nh3 = 63.58 g nh3 is produced</span>
Answer:
1056.8 kJ
Explanation:
A sample of gas in a cylinder is provided with 623.9 kJ of heat. By convention, when the gas absorbs heat, it takes a positive sign, so Q = 623.9 kJ.
A piston then compresses the gas by doing 432.9 kJ of work to the gas. We work is done on the gas, it takes a positive sign, so W = 432.9 kJ.
The change in the internal energy (ΔU) is:
ΔU = Q + W
ΔU = 623.9 kJ + 432.9 kJ = 1056.8 kJ
Might be false
Hope so
So sorry if it is wrong
