Where does acid rain occur?

vlabodo [156]

<span>Acid rain is precipitation that contains high levels of nitric or sulfuric acid. Natural and industrial sources can release sulfur dioxide and nitrogen oxide into the atmosphere, leading them to combine chemically with oxygen and water to form their respective acidic molecules. These acids are then deposited through rain or dust depending on the climate of the region. While acid rain can occur anywhere in the world, it is prevalent in regions that have high industrial activity.</span>

A 5.00 gram sample of an oxide of lead PbxOy contains 4.33 g of lead. Determine simplest formula for the compund

Harrizon [31]

Answer: The empirical formula is $PbO_2$

Explanation:

Mass of Pb = 4.33 g

Mass of O = (5.00-4.33) g = 0.67 g

Step 1 : convert given masses into moles

Moles of Pb = $\frac{\text{ given mass of Pb}}{\text{ molar mass of Pb}}= \frac{4.33g}{207g/mole}=0.021moles$

Moles of O = $\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{0.67g}{16g/mole}=0.042moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Pb = $\frac{0.021}{0.021}=1$

For O = $\frac{0.042}{0.021}=2$

The ratio of Pb O= 1: 2

Hence the empirical formula is $PbO_2$

Viktor [21]

Explanation:

Given that sodium butylite is reacting with 1-chloro-3-methyl butane. In a reaction 6-methyl nona-3-yne and sodium chloride will be obtained as product.

The chemical reaction:

$CH_3-CH_2C\equiv C-Na^++(CH_3)_2CH-CH_2-CH_2-Cl\rightarrow CH_3-CH_2C\equiv C-CH_2-CH_2-(CH_3)_2+NaCl$

The reaction is also attached as image for reference.
