Answer:
66.57%
Explanation:
The decomposition reaction of calcium carbonate is shown below as:
Calculation of moles of 
:
Amount = 3.32 g
Molar mass of = 100 g/mol
The formula for the calculation of moles is shown below:
Thus, moles are:
According to reaction,
0.0332 moles of decomposes to yield 0.0332 moles of 
Theoretical yield = 0.0332 moles
Calculation of moles of formed as:
Amount = 1.24 g
Molar mass of = 56 g/mol
The formula for the calculation of moles is shown below:
Thus, moles are:
Experimental yield = 0.0221 moles
Thus,
<u>Percent yield = 66.57%</u>
Answer:
John Dalton described the atoms based on there chemical and physical properties of which some were disproved later.
Explanation:
John Dalton described the atoms as
- Atoms are the smallest indivisible particles of matter.
- Atoms can neither be created nor destroyed.
- All atoms of the same element are identical by mass and size.
- Atoms of the different element have different mass and size.
- Atoms combined to form a compound and they do so in simply whole number ratio.
Answer:2-methylpropane
Explanation:
The structure of 2-methylpropane is contrasted with that of propane in the image attached. It is easy to see that 2-methylpropane contains a tertiary carbon atom which forms a stable radical. This stable radical formed will eventually lead to the yield of a single product which is 2-chloro-2-methylpropane. A tertiary radical is the most stable radical and often leads to the formation of a single product.

Answer:A typical gasoline mixture contains about 150 different hydrocarbons, including butane, pentane, isopentane and the BTEX compounds (benzene, ethylbenzene, toluene, and xylenes). Gasoline also contains chemicals such as lubricants, anti-rust agents and anti-icing agents that are added to improve car performance.
