Which coefficients correctly balance the formula equation below? NH 4 NO 2 (s) N 2 (g)+H 2 O(l) A. 1, 2, 2 C. B. 2, 1, 2 D. 1, 2
Arte-miy333 [17]

The coefficients which correctly balance the formula for the equation of reaction of NH₄ and NO₂ is 1,1,1,2.

<h3>What is a Balanced Chemical reaction?</h3>

This is the type of reaction in which the atoms of the elements of the reactants equal that of the product.

The balanced reaction is seen below where 2 was added to H₂O so as to balance the atoms of oxygen on both sides.

NH₄ + NO₂ (s) ⇒ N₂ (g)+2H₂O(l)

What is oxidized and what is reduced in this reaction? cu(s) 2agno3(aq) → cu(no3)2(aq) 2ag(s) cu is reduced and ag is oxidized.
Luden [163]

From the  reaction equation,  Cu is oxidized in the reaction while Ag is reduced.

<h3>What is a redox reaction?</h3>

The term redox reaction has to do with a reaction in which a specie is oxidized and another is reduced.

Here the reaction equation is; Cu(s) + 2AgNO3(aq) → Cu(NO3)2(aq) 2Ag(s) Cu. We can see that Cu is oxidized in the reaction while Ag is reduced.

What mass in grams of hydrogen is produced by the reaction of 2.0 g of magnesium? (Make sure to balance the reaction first)
denpristay [2]

Answer:

0.164541341 g H2

Explanation:

1) Convert grams to moles by dividing by RMM of Magnesium (24.31g).

  2g Mg * (1 mol Mg / 24.31 g Mg) = 0.082270671 mol of Mg

2) Use the balanced equation's ratio of 1 mol Mg: 1 mol H2.

  0.082270671 mol of Mg = 0.082270671 mol of H2

3) Convert the mol of H2 back into grams by multiplying by H2's RMM (2 g).

  0.082270671 mol of H2 * 2 g H2 = 0.164541341 g H2

* Answer can be rounded to your liking *
