Answer:
80.13g of SO2
Explanation:
4FeS2 + 11O2 —> 2Fe2O3 + 8SO2
Molar Mass of FeS2 = 55.8 + (2x32) = 119.8g/mol
Mass of FeS2 from the balanced equation = 4 x 119.8 = 479.2
Molar Mass of SO2 = 32 + (16x2) = 32 + 32 = 64g/mol
Mass of SO2 from the balanced equation = 8 x 64 = 512g
From the equation,
479.2g of FeS2 produced 512g of SO2.
Therefore, 75g of FeS2 will produce = (75 x 512)/479.2 = 80.13g of SO2
5 i believe the right answer
Answer:
1-(tert-butoxy)-2-methylpropane
Note: there is a mistake in formula, the correct formula is (CH₃)₂-CH-CH₂-O-C(CH₃)₃ not (CH₃)₂-CH-CH₂-O(CH₃)₃, because oxygen is a divalent compound.
Explanation:
<em>Structural formula is attached</em>
IUPAC naming rules
1. start numbering the chain from the functional group. In this compound we start from oxygen side.
2. Here we can see that at position 1 there is an oxy group along with a tertiary carbon having three methyl groups. So we write it as 1-tert-butoxy. Which means that there is a methoxy group at position 1 along with a tertiary carbon.
3. At position 2 we can see that there is a methyl group attached to the main chain, so we write it as 2-methyl.
4. Now we count the total number of carbons in the main chain. As we can see that there are 3 carbons in the remaining or parent chain, so we write it as propane
5. So the IUPAC name of the compound will be 1-(tert-butoxy)-2-methylpropane
