Answer:
10 N
Explanation:
The pair of 5 N is pressing on 1 side of the square
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:
Uganda takes its name from the Buganda kingdom, which encompasses a large portion of the south of the country, including the capital Kampala. The people of Uganda were hunter-gatherers until 1,700 to 2,300 years ago, when Bantu-speaking populations migrated to the southern parts of the country.
Explanation:
1) - it can become a theory if the hypothesis is <span>tested extensively and competing hypotheses are eliminated - other options are not enough
2) This is a hypothesis. A theory is basically almost an established truth, which can still be changed with new data, but which as far as we know is true.</span>
