No. of moles of calcium chloride = molarity × volume of solution in L
No. of moles of calcium chloride = 2.5 ×0.5 = 1.25 mole
No. of moles of calcium chloride = mass of calcium chloride / molar mass of calcium chloride
1.25 mole = mass of calcium chloride / 110.98 g/mol
mass of calcium chloride = 1.25 ×110.98 = 139 g

Answer:
The Spaniards practically went to war with the native Americans in South America, such as the Inca. They also brought diseases to South America. Diseases like smallpox.
Explanation:
Then after effectively killing off most of the native American population the Spanish continued to use South America for resources and they enslaved most of what was left of the non-Spanish and mixed populations. Francisco Pizarro took a page from Cortes' book, capturing Atahualpa, Emperor of the Inca, in 1532 and Cortes was the conquistador who defeated the Aztec Empire in what is now modern day Mexico or Central America.
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
I have no idea, but i’m pretty sure you gotta divide
