Lynna [10]

The pressure in the flask is 3.4 atm.

<em>pV</em> = <em>nRT </em>

<em>T</em> = (20 + 273.15) K = 293.15 K

<em>p</em> = (<em>nRT</em>)/<em>V</em> = (1.4 mol × 0.082 06 L·atm·K⁻¹mol⁻¹ × 293.15 K)/10 L = 3.4 atm

Photochemical chlorination of pentane gave a mixture of three isomeric monochlorides. The principal monochloride constituted 46%
meriva

Answer:

Explanation:

In the chlorination of alkanes, the condition necessary is UV light so free radical substitution can take place. For alkanes like pentane, the primary, secondary and tertiary Hydrogen atoms (Hydrogen atoms bonded to their respective carbon) þare taken into consideration and this is because the tertiary Hydrogen is the most reactive (due to bond dissociation energy) hence the easiest to be substituted. The trend is as follows in the order of their reactivity;

1° < 2° < 3°

So, the products of the chlorination of pentane, the principal monochloride constituted is 3 - chloropentane while the other two monomers are:

2- chloropentane

1- chloropentane

Below is the attachment showing the structural formula of the three monochloride constituted pentane.

What mass of zinc oxide would be produced by the thermal decomposition of 375 grams of zinc carbonate?
Llana [10]
Zinc carbonate has the chemical formula : ZnCO3 and the equation for thermal decomposition is:
ZnCO3 .................> ZnO + CO2
1 mole of ZnCO3 produces one mole of ZnO

From the periodic table:
molar mass of zinc = 65.38 gm
molar mass of carbon = 12 gm
molar mass of oxygen = 16 gm

molar mass of ZnCO3 = 65.38 + 12 + 3(16) = 125.38 gm
molar mass of ZnO = 65.38 + 16 = 81.38 gm

125.38 gm of ZnCO3 produces 81.38 gm of ZnO, therefore:
mass of ZnO in 375 gm = (375 x 81.38) / 125.38 = 243.4 gm

Based on the above calculations, the correct answer is 243 grams
