Since SeO2 dissolves in water to produce selenium acid, it is regarded as an acidic oxide.

The chemical compound having the formula SeO2 is known as selenium dioxide. One of the forms of selenium that is most frequently seen is this colorless solid. 350 °C (662 °F; 623 K). The chemical compound having the formula SeO2 is known as selenium dioxide. One of the forms of selenium that is most frequently seen is this colorless solid. It serves as a catalyst, reagent, oxidizing agent, and antioxidant in lubricating oils. OSHA regulates selenium oxide; thus, it is listed on the Hazardous Substances List. It can be produced chemically by dehydrating selenous acid or chemically by burning selenium in oxygen, nitrogen dioxide, or hydrogen peroxide.

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is A

That is 2,4,5-Trimethyl-4-propylheptane

Explanation:

Looking at the structure the longest carbon chain is 7 as shown on the second uploaded image

Also from the diagram of the structure we can identify that is longest chain has 3 methyl group attachment and one propyl group attachment

Now going through this longest chain the numbering of this attachment them the lowest number is the correct way so as we can see

2,4,5-Trimethyl-4-propylheptane gives the lowest numbering compared to 3,4,6-Trimethyl-4-propylheptane so the correct IUPAC names is 2,4,5-Trimethyl-4-propylheptane

Limestone (CaCO₃) is used to remove acidic pollutants from smokestack flue gases. It is heated to form lime (CaO), which reacts

Alex

To completely eliminate all of the SO2 produced by coal burning, 1250.62 kg of CaCO3 are required.

Equation

CaCO₃ --->CaO + CO2

2 CaO +2 SO2 ----> 2 CaS + 3O2

overall reaction

2 CaCO₃ +2 SO2 ---> 2 CaS + 3O2 + 2CO2

m(S)=8,5 x 10^{4}*0.0033=280.5 kg

n(SO2)= m/Ar(S) = 8,75 x 10^{3}mol

n(CaCO3 needed) = n(SO2) / percent yield

n(CaCO3 needed) = 8.75 x 10^{3}mol / 0.7

n(CaCO3 needed)= 1.25 x 10 ^4 mol

m(CaCO3 needed) = n x Mr = 1250.62kg

To completely eliminate all of the SO2 produced by coal burning, 1250.62 kg of CaCO3 are required.

<h3>Where Is Limestone Found?</h3>

Numerous locations that produce limestone have been recognized by geologists throughout the world. Between 30o N and 30o S latitude, the most of them are in shallow waters. The Caribbean Sea, Indian Ocean, Persian Gulf, and the Gulf of Mexico are the most well-known shallow water locations.
