Answer:
Vegetable oil will dissolve in heptane
Isopropyl alcohol will dissolve in water
Potassium Bromide will dissolve in water
Explanation:
In chemistry, like dissolves like. This implies that polar substances will dissolve in polar solvents and nonpolar substances will dissolve in nonpolar solvents. This is so because, dissolution of a solute in a solvent involves adequate intermolecular interaction between solute and solvent which isn't possible between a polar and a nonpolar substance.
The different state of material based on its ingredients are-
1. Compound: The compound is in which there are more than one molecule in which chemical bond is there.
2. Mixture: It is basically presence of two or more compounds in which there is no chemical bonds.
The mixture may be of two types (i) homogeneous and (ii) Heterogeneous. In the homogeneous mixture there is uniformity of the mixed compound (like air in water) and some chemical process is needed to separate the compounds. Whereas heterogeneous mixtures (like chalk in water) are easily separable by any physical process.
In the root beer which is a soft drink which is obtained in different flavor sometime with caffeine and without caffeine. The unopened bottle of root beer is homogeneous mixture.
Interphase is not a phase of mitosis.
The total energy required for this conversion is equivalent to the sum of the energies that are used. There are three steps:
1) Heating of liquid acetone
This used 628 J
2) Evaporation of acetone
This used 15.6 kJ or 15,600 J
3) Heating of acetone vapors
This used 712 J
Adding these quantities,
Total energy = 628 + 15,600 + 712
The total energy required was <span>16940 Joules of 16.94 kJ</span>
