Explain Why P-bromonitrobenzene Predominates In The Product Mixture Over O-bromonitrobenzene?
P-bromonitrobenzene predominates in the product mixture over O-bromonitrobenzene due to the directing effects of the nitro group on the aromatic ring. The nitro group is a strong deactivating and meta-directing substituent, which means that when bromination occurs, it favors substitution at the para position rather than the ortho position. This is because the para position is less sterically hindered compared to the ortho position, allowing for a more favorable reaction pathway. Consequently, the steric and electronic factors lead to a higher yield of p-bromonitrobenzene.

Explain how concrete is a mixture and not a pure substance?
Concrete is a mixture of different substances (compounds) not a sinle compound.
Is an alloy a pure substance or a mixture use the particle theory to explain?
Neither, try again.
How will you separate a mixture of salt and sand will it be different if the mixture consists of iron filling instead of salt explain?
To separate a mixture of salt and sand, you can use the method of dissolving the salt in water and then filtering the sand out. If the mixture consists of iron filings instead of salt, you can use a magnet to attract and separate the iron filings from the sand. This method works since iron is magnetic while sand is not.
Explain the term phase as it relates to homogenous and heterogenous mixtures?
In a homogeneous mixture, the components are uniformly distributed, so the mixture is considered a single phase. In a heterogeneous mixture, the components are not uniformly distributed, resulting in multiple phases or visibly distinct regions within the mixture. Phase refers to the physical state of matter within a system, such as solid, liquid, or gas.
Is a solution a mixture explain?
Yes, it is a type of mixture as mixtures are made of 4 categories: Mechanical Mixture (which is different than a solution), Colloid, Suspension, and Solution. So yes, a solution is a type of mixture just not a Mechanical Mixture.
Explain how concrete is a mixture and not a pure substance?

Is evidence of a chemical change?
Explain how a mixture of sand and salt can be separated.
Could a mixture be made up of only element and compounds explain?
Yes. For example, brass is a mixture of copper and zinc. A mixture of metals is called an alloy. A mixture of inert gases (e.g. helium, argon, neon, xenon, krypton, radon).

Is aluminium a mixture or a compound or an element Explain the question?
Aluminium is a chemical element because all atoms are identical.
Would the oils and sweat make a homogeneous mixture or a heterogeneous mixture Explain your answer?
Oils and sweat would form a heterogeneous mixture because they are immiscible, meaning they do not dissolve into each other. The oils would float on the sweat, creating distinct layers within the mixture.
Explain the term homogeneous and stratified with respect to mixture preparation in a petrol direct injection engine?
two tone farts
Is it possible to have a solution that is not a mixture explain your answer?
No, because a solution is a homogenous mixture, meaning it is composed of at least 2 substances that are mixed together, but not combined chemically, and the mixture does not look like multiple substances with the naked eye.
