Hello,
You balanced the equation and then you have to set up what is called a psychometric equation for each reactant so that you get the same unit for each in order to compare the two. so for (calcium hydroxide) = 78.5 g ÷ (40.1 + 32 + 2) = 1.0593 mol * Note: I just broke it down in my own science way..u can just get the molar mass of calcium hydroxide which is approx 74 g/mol
Hope this helps
The overall enthalpy of reaction will be calculated from enthalpy of formation of products and reactants.
DeltaHrxn = [Sum of enthalpy of formation of products] - [sum of enthalpy of formation of reactants]
DeltaHrxn = 3 X deltaHf (H2O) - [ 3 X DeltaH (H2) + DeltaH (O3)]
DeltaHrxn = 3 X (--242) - [ 0 + 143] = -869 kJ / mole
We can also calculate the enthalpy of reaction from bond energies
Answer:
Pangaea
Explanation:
About 300 Million Years Ago, Earth Didn't Have Seven Continents But Instead Earth Had One Massive Super continent Called Pangaea.
The Calvin Cycle is the process that will be the last one to be affected by shorter periods of daylight. Carbon dioxide goes in the interior of a leaf through pores of plants, which is called stomata and spreads into the stroma of the chloroplast this is the site of the Calvin cycle reactions, wherein sugar is produced and synthesized. These reactions are also called the light-independent reactions because they are not directly driven by light.
