2NO(g) N2(g) + O2(g); Keq = 2.1 × 1030 What does the value of the equilibrium constant indicate?

1 answer:

7 0

The equilibrium constant is a value which represents the equilibrium of a reaction. It is a reaction quotient when the reaction reached equilibrium. If Keq is greater than 1, the mixture contains mostly the products. On the other hand, if Keq is less than 1, the mixture contains the reactants. For this case, the mixture contains mostly products.

In a common experiment in the general chemistry laboratory, magnesium metal is heated in air to produce MgO. MgO is a white soli

Digiron [165]

Explanation:

When magnesium metal burns is heated i the air it forms magnesium oxide.The balanced chemical reaction is given as:

$2Mg+O_2\rightarrow 2MgO$

2 moles of magnesium metal when reacts with 1 moles of oxygen it gives 2 moles of magnesium oxide which is white in color.

Some times along with formation of magnesium oxide small amount of magnesium nitride also produced due to which magnesium oxide appears grey in color .The balanced chemical reaction is given as:

$3Mg+N_2\rightarrow Mg_3N_2$

3 moles of magnesium combines with 1 mol of nitrogen gas to to give 1 mol of magnesium nitride.

For the reaction, calculate how many grams of the product form when 14.4 g of Br2 completely reacts. Assume that there is more t

lora16 [44]

Answer:

The answer to your question is 21.45 g of KBr

Explanation:

Chemical reaction

2K + Br₂ ⇒ 2KBr

14.4 ?

Process

1.- Calculate the molecular mass of bromine and potassium bromide

Bromine = 2 x 79.9 = 159.8g

Potassium bromide = 2(79.9 + 39.1) = 238 g

2.- Solve it using proportions

159.8 g of Bromine ------------ 238 g of potassium bromide

14.4 g of Bromine ------------ x

x = (14.4 x 238) / 159.8

x = 3427.2 / 159.8

x = 21.45g of KBr

A sample of a substance that has a density of 0.844 g/mL has a mass of 0.549 g. Calculate the volume of the sample.

Virty [35]

D = m / V

0.844 = 0.549 / V

V = 0.549 / 0.844

V = 0.650 mL
