Answer:
See attachment.
Explanation:
Mono-substituted cyclohexanes are more stable with their substituents in an equatorial position. However, with poly-substituted cyclohexanes, the situation is more complex since the steric effects of all substituents have to be taken into account. In this case, you can see that <u>the interconversion is shifted towards the conformation in the bottom because there is less tension between the substituents</u>.
Explanation: A <u>homogeneous mixture</u> is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample. The components that make them up are evenly distributed and the appearance of the solution is uniform throughout.
A<u> heterogeneous mixture</u> has components whose proportions vary throughout the sample. The components of a heterogeneous mixture are visible and not uniform throughout. A heterogeneous mixture is simply any mixture that is not uniform in composition.
a) Peanuts and almonds mixed together in a bowl : The components(Peanuts and almonds) are visible in a bowl and are not evenly distributed and also not uniform throughout. So this is a 'heterogeneous mixture'.
b) Bucket full of sand and gravel : The components(sand and gravel) are visible in a bucket and are not evenly distributed and also not uniform throughout. So this is a 'heterogeneous mixture'.
c) Cup of tea and sugar : The components(tea and sugar) are evenly distributed and the appearance of the solution is uniform throughout. So this is a 'Homogeneous mixture'.
d) Food coloring dissolved in water : The components(Food coloring and water) are evenly distributed and the appearance of the solution is uniform throughout. So this is a 'Homogeneous mixture'.
