Answer:

Hope this helped :) good luck! ❤️

Answer: Ammonium, when heated with aqueous base, will give off NH3 (ammonia) gas, (and depending, water vapor). This will leave the Cr2O3(s). From then on,

it is just adding or subtraction of gases or water vapor. You probably heard “Loss of electrons is Oxidation”, “Gain of Electrons is reduction”. That should help.

Explanation: This isn’t an explanation but an interesting point; Acid-Base and RedOx reactions are useful to the most complex of any Chemistry. Get this down, and Organic Chemistry will be much easier.

Write the reaction from the word equation and then balence the equation
Mars2501 [29]
<h3>Answer:</h3>

Ni + Pb(NO₃)₂ → Ni(NO₃)₃ + Pb

<h3>Explanation:</h3>

We are required to write a balanced equation from the word equation;

  • Nickel reacts with lead nitrate (II) to produce nickel(III) nitrate and lead
  • The equation will be written by writing the symbols of the reactants and products.

That is;

Ni + Pb(NO₃)₂ → Ni(NO₃)₃ + Pb

We then balance the equation;

  • To balance the equation, we put appropriate coefficients on reactants and products, so that the number of atoms of each element is equal on both sides of the equation.
  • Thus, the balanced equation will be;

2Ni + 3Pb(NO₃)₂ → 2Ni(NO₃)₃ + 3Pb
