Answer:

2 x 2 = 4

Explanation:

Multiplication is just doubling the numbers depending on what you have. 3 x 3 = 9 because 3 three times is 9. Therefore, 2 two times is 4.

Experiments have shown that the equilibrium constant Kp for the reaction NO(g) + NO2(g) ⇌ N2O3(g) is 0.03. A chamber with a cons

zepelin [54]

Answer:

The reaction will shift to the right

Explanation:

In the reaction:

NO(g) + NO₂(g) ⇌ N₂O₃(g)

Kp of reaction is:

$kP = \frac{P_{N_2O_3} }{P_{NO}P_{NO_{2}}}$ = 0.03

Where P represents the pressures in equilibrium

Replacing in the kP formula the initial pressures:

$\frac{50MPa}{200MPa*250MPa}$ = 0.001

As the Reaction quotient (Q) is less than kP, the reaction will shift to the right producing more N₂O₃ until Q = kP.

How long for dissolvable stitches to dissolve in nose

Papessa [141]

The time it takes for dissolvable or absorbable stitches to disappear can vary. Most types should start to dissolve or fall out within a week or two, although it may be a few weeks before they disappear completely. Some may last for several months

A hydrocarbon is burnt completely to give 3.447g of

goblinko [34]

Answer: The empirical formula for the given compound is $CH_2$

Explanation:

The chemical equation for the combustion of compound having carbon, hydrogen, iron and oxygen follows:

$C_xH_y+O_2\rightarrow CO_2+H_2O$

where, 'x' and 'y' are the subscripts of carbon and hydrogen respectively.

We are given:

Mass of $CO_2=3.447g$

Mass of $H_2O=1.647g$

We know that:

Molar mass of carbon dioxide = 44 g/mol

Molar mass of water = 18 g/mol

For calculating the mass of carbon:

In 44g of carbon dioxide, 12 g of carbon is contained.

So, in 3.447 g of carbon dioxide, $\frac{12}{44}\times 3.447=0.940g$ of carbon will be contained.

For calculating the mass of hydrogen:

In 18g of water, 2 g of hydrogen is contained.

So, in 1.647 g of water, $\frac{2}{18}\times 1.647=0.183g$ of hydrogen will be contained.

To formulate the empirical formula, we need to follow some steps:

Step 1: Converting the given masses into moles.

Moles of Carbon = $\frac{\text{Given mass of Carbon}}{\text{Molar mass of Carbon}}=\frac{0.940g}{12g/mole}=0.0783moles$

Moles of Hydrogen = $\frac{\text{Given mass of Hydrogen}}{\text{Molar mass of Hydrogen}}=\frac{0.183g}{1g/mole}=0.183moles$

Step 2: Calculating the mole ratio of the given elements.

For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 0.0783 moles.

For Carbon = $\frac{0.0783}{0.0783}=1$

For Hydrogen = $\frac{0.183}{0.0783}=2.34\approx 2$

Step 3: Taking the mole ratio as their subscripts.

The ratio of C : H = 1 : 2

Hence, the empirical formula for the given compound is $CH_2$
