Br2 is the correct answer
Answer:
The Fischer Projection formula of D-glucose is as shown in the attachment below.
The chiral centre that determines its name is the last carbon from the carbonyl group, C-6
Explanation:
Fisher projection formulas are used to show sugars in their open chain form. In a Fischer projection, the carbon atoms of a sugar molecule are joined vertically by solid lines, while carbon-oxygen and carbon-hydrogen bonds are joined horizontally using solid lines as well.
The horizontal bonds project out of the plane of the paper or screen towards the reader whereas vertical bonds project behind the plane of the paper or screen, away from the reader.
Glucose is an aldose sugar with two different optical isomers or enantiomers, D-glucose and L-glucose. The designation D- or L- depends on the configuration of the chiral or asymmetric carbon most distant from the carbonyl carbon of glucose. If the chiral carbon has the same configuration as D-glyceraldehyde, that the -OH roup on the right side of the carbon and -H group on the left, it is snamed D-glucose. However, if the chiral carbon has the same configuration as L-glyceraldyde, that is with the -OH group on the right and the -H group on the right, it is named L-glucose
The process of hydrogenation changes the double bonds in unsaturated fatty acids into single bonds, giving the fat a more solid consistency.
<h3>Hydrogenation of fat</h3>
Fat can be defined as one of the main classes of food that is made up of triesters of glycerol and fatty acids or triglycerides.
At room temperature, fats are solids, while those that are liquid at room temperature are called oils.
Fats can be saturated or unsaturated. But an unsaturated fat can be made saturated through the process of hydrogenation.
Hydrogenation of fat can be defined as the addition of hydrogen in the presence of nickel catalyst to form saturated fat.

Answer:
the pressure would be 0.9 atmospheres
Explanation:
you just gotta add the presures for each of the gases that are added
Answer:
Th answer is b. convection.
Explanation:
As the heat rises it cools down and it sinks and as the cold sinks it heats up so then it rises back up.
