Answer:

ΔG < 0

Explanation:

The condition for spontaneity of a chemical reaction is that ∆G<0. Hence for any biochemical reaction to proceed as written, ∆G must have a negative value.

If ∆G >0, the reaction is not spontaneous and will not proceed as written. ∆G=0 means that the reaction has attained equilibrium.

QUESTION 21 The combustion of ammonia in the presence of excess oxygen yields NO 2 and H 2O: 4 NH 3 (g) 7 O 2 (g) 4 NO 2 (g) 6 H
Harrizon [31]

Answer:

The answer to your question is 47.44 g of Oxygen

Explanation:

Data

mass of Ammonia = 14.4 g

mass of Oxygen = ?

Balanced chemical reaction

                 4NH₃  +  7O₂  ⇒  4NO₂  +  6H₂O

Process

1.- Calculate the molar mass of Ammonia

NH₃ = 4[(1 x 14) + (3 x 1)] = 4[14 + 3] = 4[17] = 68 g

2.- Calculate the molar mass of Oxygen

O₂ = 7[16 x 2] = 7[32] = 224 g

3.- Use proportions to calculate the mass of Oxygen

                     68g of NH₃ --------------------- 224 g of O₂

                      14.4 g of NH₃ -----------------  x

                       x = (14.4 x 224) / 68

                       x = 3225.6/ 68

                       x = 47.44 g

Lana71 [14]

Answer:

Diamond - E

Sugar- C

Milk - M

Iron- E

Air- M

Sulfuric Acid- C

Gasoline - M

Electricity- X

Krypton- E

Bismuth - E

Uranium - E

Kool-Aid -M

Water - C

Alcohol - C

Pail of Garbage - M

Ammonia - C

Salt - C

Energy - X

Gold - E

Wood - M

Bronze - M

Ink - M

Pizza - M

Dry Ice - C

Baking Soda - C

Explanation:

An element is the smallest part of a substance that is capable of independent existence. An element cannot be broken down into any other substance. Krypton, Bismuth etc are all elements.

A compound is a combination of two or more elements which are chemically combined together e.g NH3, CO2 etc.

A mixture is any combination of substances that are not chemically combined together. E.g Pizza, milk etc
