nitrogen fixation is the process through which the nitrogen fixing rhizobium bacteria present in the root nodules of leguminous plants I fixes the nitrogen present in the air into the soil
Answer: B) -4819 kJ
Explanation:
The balanced reaction for combustion of octane is:

To calculate the number of moles, we use the equation:
given mass of octane = 100.0 g
Molar mass of octane = 114.33 g/mol
Putting in the values we get:

According to stoichiometry:
2 moles of octane give heat = -11018 kJ
Thus 0.8747 moles of octane give =
Thus -4819 kJ of heat is released by 100.0 g of octane assuming complete combustion.
Answer:
The solution is a base
Explanation:
A basic solution changes red litmus paper to blue. This is one unique property of a base that differentiate them from All other compound
10 atoms. If there are 10 in the reactants you need the same number in the products
