What are the missing coefficients for the skeleton equation below?

Chemistry
1 answer:
Kruka [31]3 years ago
4 0

Answer:

4, 3 , 2 and 6

Explanation:

The reaction equation is given as;

       NH₃  +  O₂   →    N₂   +   H₂O

Now, we need to balance the reaction equation;

     NH₃  +  O₂   →    N₂   +   H₂O

put the numbers a,b,c and d;

    aNH₃  +  bO₂   →    cN₂   +   dH₂O  

We need to balance the equation algebraically, ;

  Conserving N;

      a = 2c

   Conserving H;

      3a  = 2d

   Conserving O;

      2b  = d

Now, let c = 1, a = 2, d  = 3 and b  = \frac{3}{2}  

  multiply through by 2;

            a  = 4, b = 3, c  = 2 and d  = 6

Insert the parameters:

                  4NH₃  +  3O₂   →    2N₂   +   6H₂O

Olenka [21]
A calorimeter contains reactants and a substance to absorb the heat absorbed. The initial temperature (before the reaction) of the heat absorbent is measured and then the final temperature (after the reaction) is also measured. The absorbent's specific heat capacity and mass are also known. Given all of this data, the equation:
Q = mcΔT 
To find the heat released.

Answer:

4Fe + 3O₂ → 2Fe₂O₃

General Formulas and Concepts:

<u>Chemistry - Reactions</u>

  • Balancing Reactions

Explanation:

<u>Step 1: Define</u>

RxN:   Fe + O₂ → Fe₂O₃

<u>Step 2: Balance</u>

We need to balance both Fe and O.

LCM of 2 and 3 is 6:

Fe + 3O₂ → 2Fe₂O₃

We now need the same amount of Fe on both sides:

4Fe + 3O₂ → 2Fe₂O₃
