Troyanec [42]4 years ago
3 0

Answer:

yeah the answer under the explanation

<em>Explanation:</em>

<em>The answer is (4) exothermic with ΔH = -1640 kJ. The 1640 kJ energy is at the right side of equation means that it releases energy. The enthalpy change means the energy of production minus the energy of reactants. If it is exothermic, the ΔH < 0.</em>

B and e

first we need to balance the NH3 hence first we do E and multiplying the coefficient by 2. that will leave us with N2+H2–>2NH3.
N2 and H2 is balanced and now all that is left to do is the balance H2 by 3 as there is 6H on RHS hence we need 6H on LHS

If you obtain 3.0 grams of aspirin from an experiment that could make no more than 3.14 grams, what is the percent yield?
Masteriza [31]

Answer:

96%

Explanation:

To find the percent yield, we can use this equation

\frac{Actual}{Theoretical} *100

The actual yield of aspirin is 3.0 and the theoretical is 3.14 in this case, so just plug the numbers in.

\frac{3.0}{3.14} *100\\\\ =96

Thus the percent yield is 96%
