Answer:
OH⁻(aq) + NH₄⁺(aq) → NH₃(g) + H₂O(l)
Explanation:
The net ionic equation is a way yo write a chemical equation that list only the species that are involved in the reaction.
For the reaction:
NaOH(aq) + NH₄Br(aq) → NaBr(aq) + NH₃(g) + H₂O(l)
Ionic equation is:
Na⁺(aq) + OH⁻(aq) + NH₄⁺(aq) + Br⁻(aq) → Na⁺(aq) + Br⁻(aq) + NH₃(g) + H₂O(l)
<em>-Ions comes from the species that are in aqueous phase-</em>
And net ionic equation is:
<em>OH⁻(aq) + NH₄⁺(aq) → NH₃(g) + H₂O(l)</em>

Answer:
The net force is 5 N and to the left.
Explanation:
37 N - 32 N = 5 N and since there is a stronger pull from the rope moves towards the left so the direction of motion is left.

To express the efficiency of a reaction, you can calculate the percent yield using this formula: %yield = (actual yield/theoretical yield) x 100.
The correct answer is D hydrogen and chlorine need to be balanced there's an equal amount of magnesium on each side. I just took the test and got the correct answer.
E=hc/λ =6.626×10^-34×3 ×10^8 / 3×10^7 × 10^-9 = 6.626×10 ^-24J.
