At the plash point, it is a chemical change (or) physical change should be determined and How about the boiling point of flash point. Concept introduction: Physical change: A change in matter in which no new substance is produced. It is may be involved a change of state and it can usually be reversed. In other words the substances at the beginning are the same before and after the change. Example: Melting, freezing and dissolving Chemical change: A change is matter in which one or more new substances are produced. It is difficult to reverse. (or) The substances present at the beginning are not present at the end. Clues: Heat (or) light may be given off, small, colour change and das may be formed. Example: Cooking, burning and rusting. Flash point: Flash point of a liquid is the lowest temperature at which it gives vapour to from an ignitable mixture with air.

(b)

Interpretation Introduction

Interpretation:

Flammable and combustible some difference and similarities should be explained.

Concept introduction:

Flammable: It is a property of a material relating how easily the material ignites (or) sustains a combustion reaction.

Ionic liquids are neither volatile nor flammable. But Organic solvents have volatile. They can contribute to air pollution, it’s easily flammable. The ionic liquid may progress the yield and lower the expenses of a chemical process. But Organic solvent is not economic.

Combustion: A chemical reaction which a substance combines with oxidant and release energy.

(c)

Interpretation Introduction

Interpretation:

The flash point of the liquids is higher or lower at higher altitudes has to be explained.

Dr. Mendel asked his BIOL 260 class what their height was and what their parent's heights were. He plotted that data in the graph below to determine if height was a heritable trait. A. Is height a heritable trait? If yes, what is the heritability value? (2 pts) B. If the phenotypic variation is 30, what is the variation due to additive alleles?

Experiment: Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.
