A student wants to test for the concentration of food dye FD&C Yellow #5 (Tartrazine) in a yellow Starburst candy. First, the student must prepare standard solutions for the calibration curve. The student has a stock solution of FD&C Yellow #5; the concentration is 0.1140 M. The student takes 6.50mL of the stock solution and dispenses it into a 50.0mL volumetric flask. The flask is then diluted to volume with water. What is the concentration of this standard solution?

Answers

The molarity of the diluted standard solution is obtained by calculation to be 0.015 M.

Recall the dilution formula;

C1V1 = C2V2

C1 = Initial concentration = 0.1140 M

V1 = initial volume =  6.50mL

C2 = Final concentration = ?

V2 = Final volume = 50.0mL

Making C2 the subject of the formula and substituting values;

C2 = C1V1/V2

C2 = 0.1140 M ×  6.50mL/50.0mL

C2 = 0.015 M

Rebekah finds that a solution of sugar in water has a volume of 1. 32 fl. Oz. How should she report this amount using the metric system? (1 fl. Oz. = 29. 6 mL) 0. 403 m 1. 40 qt 37. 5 g 39. 1 mL.

Answers

Rebekah reports the volume of sugar solution using metric system as 39.1 mL. Thus, option D is correct.

The metric system has been the measurement system introduced in 1790s. The system has mediated the units for the measurement of volume, mass, length.

The volume has been the space that has been occupied by matter. The volume can be denoted with SI unit L. However, the another accepted unit for volume has been mL.

Thus, the volume of sugar solution has been reported in mL.

The given sugar solution has volume of 1.32 fl. Oz

The volume in mL can be given as:

[tex]\rm 1\;fl\;Oz=29.6\;mL\\1.32\;fl\;Oz=1.32\;\times\;29.6\;mL\\1.32\;fl\;Oz=39.1\;mL[/tex]

The volume of the sugar solution reported by Rebekah on the metric scale has been 39.1 mL. Thus, option D is correct.

Using the “rule of 8” explain why carbon is the backbone of organic molecules

Answers

Answer:

Carbon has 4 valence electrons (electrons that are used in bonding), and therefore it can make 4 bonds which is the most one can (other than some exceptions, but in general it is the most). It wants to make 4 bonds so it can reach a full octet of 8 elections, hence the rule of 8.

Explanation:

Answer:

I suggest you See Explanation. But tldr: Carbon forms four bonds with no lone pairs.

Explanation:

By "rule of 8" I am assuming you mean "Octet Rule." In case you don't know, the octet rule (or rule of 8) is a rule referring to the maximum number of valence shell electrons that an atom can hold: 8 electrons. However, there are exceptions to this: octet-deficient and expanded octet atoms. Octet-deficient atoms follow what is known as the duet rule (or rule of 2), as seen in the case of H and He, or have have a capacity of up to 6 electrons in their valence shell, as seen in the case of B and Be. Expanded octets contain 10, 12, or even 14 electrons and occur in Period 3 elements and after. (It was previously assumed that this was due to d-orbital hybridization but that hypothesis has been disproven and currently an explanation regarding expanded octets doesn't exist. Yet another Nobel Prize worthy concept to solve when you have free time!)

Anyways, how does this all apply to Carbon being the backbone of the millions of organic molecules? Well, carbon follows the octect rule. Unlike duet rule atoms, it is not limited to one bond with another atom. Neither does it hold many lone pairs to itself nor form over four bonds at once causing a decrease in stability. No, Carbon forms four bonds with no lone pairs and has perfect stability in terms of both formal charge and octect rule in many of its structures. Its capacity to bond to up to 4 atoms without comprimising stability is the reason why carbon is the backbone of organic molecules.

What mass of aluminum must react with 100 g of copper (ii) phosphate? (10g)

Answers

it would be 10g or 50g

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.42g of aluminum must react with 100 g of copper (ii) phosphate.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

mole =given mass ÷ molar mass

2 Al + 3 Cu[tex]_3[/tex](PO[tex]_4[/tex])[tex]_2[/tex] → Al[tex]_2[/tex] (PO[tex]_4[/tex])[tex]_3[/tex]+ 3 Cu

moles of copper phosphate= 100 g/380.58

                                               =0.26 moles

3 moles of copper sulphate need 2 mole of Al

0.26 moles of copper sulphate need (2/3)×0.26

                                                         =0.17moles

mass of Al= 0.17×26

                  =4.42g

Therefore, 4.42g of aluminum must react with 100 g of copper (ii) phosphate.
