Gas is the most compressible at room temperature.
Answer:
D) 0 k.cal per 4 grams
Explanation:
Genarally, glucose can be classified into two enantiomers such as d-glucose and l-glucose. The d-glucose is the most common sugar that bodies of living organisms use as source of energy. However, l-glucose is an organic compound and it is one of the aldohexose monosaccharides. It is the l-isomer of glucose and commonly refer to as a low-calorie sweetener. The l-glucose is relatively indistinguishable in taste from d-glucose but cannot be used as a source of energy. Therefore, in the given problem:
if d-glucose has an estimated caloric value of 1 k.cal per 4 grams of carbohydrate, then the caloric value of l-glucose will be 0 k.cal per 4 grams.
Answer:
well it is because of mainly what we call reaction the petrol are highly reactive with the flames
Fractional distillation<span> is essentially the same as </span>simple distillation<span>except that a fractionating column is placed between the boiling flask and the condenser. The fractionating column is usually filled with glass or plastic beads. These beads improve the separation between the liquids being </span>distilled<span>.</span>
The density of silver can be calculated by using the following formula:
Here, m is mass and V is volume.
To calculate density, mass of silver needs to be calculated first.
In FCC, the number of Ag atoms in a unit cell will be 4, atomic mass of Ag is 107.87 g/mol and number of atoms in 1 mol are 
atoms, thus, mass can be calculated as follows:
.
Now, volume can be calculated as follows:
First convert pm to cm:
Thus,
Putting the value to calculate volume,
Now, calculate density as follows:
Therefore, density of silver is 
.
