I WILL GIVE BRAINLIEST!Pentan-2-ol was heated with an acidified solution of potassium dichromate. Name the product(s) of this reaction.
A) Pentanoid acid
B) Pentanal
C) Pentan-2-one
D) Propanoic acid and ethanoic acid

Answers

Answer 1
Answer:

Answer:

C) Pentan-2-one

Explanation:

The product of the reaction of pentan-2-ol with acidified potassium dichromate is pentan-2-one.

Pentan-2-ol is a secondary alcohol, and secondary alcohols are oxidized to ketones by acidified potassium dichromate. The reaction is as follows:

CH3CH(OH)CH3 + K2Cr2O7 + H2SO4 → CH3COCH3 + Cr2(SO4)3 + K2SO4 + H2O

Propanoic and ethanoic acids are not products of this reaction.

Therefore, the answer is (C).

If you change the number of an atom has, it becomes a different element. If you change the number of it has, it becomes a different isotope.

Answers

Answer:

If you change the number of protons an atom has, it becomes a different element. If you change the number of nutrons it has, it becomes a different isotope.

Explanation:

Why does it make sense that if an atom loses electrons, it is left with a pisitive charage?

Answers

Because atoms are neutral. By neutral, I mean that; there are three main particles that make up an atom. Protons, Electrons and Neutrons. Protons have (electrically) positive charge, electrons have negative and neutrons are electrically neutral. One proton's charge is +1 and one electron's charge is -1. An atom (normally) has the same amount of protons and electrons. Let's say if an atom has two protons and two electrons, the sum of electrical charges of the protons is (two times +1) +2 and sum of electrical charge of electrons is (two times -1) -2 . The total charge of the atom is the sum these. So, (-2)+(2)= 0. That makes the charge of the atom 0, thus makes it neutral. But let's say this atom loses one of its electrons, and now has only one. So one electron (-1) and two protons (+2) in total will be : (-1)+(2) = +1 . +1 is positive, so this makes the charge of the atom positive.

Electrons have a net negative charge, therefore by losing them the atom will become slightly more positive.

How many mL of a stock solution of 2.00 M KNO3 are needed to prepare 100.0 mL of 0.15M KNO3? with work plz

Answers

Using the law of dilution :

Mi x Vi =  Mf x Vf

2.00 x Vi = 0.15 x 100.0

2.00 x Vi = 15

Vi = 15 / 2.00

Vi = 7.5 mL

hope this helps!


How many grams of sodium chloride are present in a 0.75 M solution with a volume of 500.0 milliliters?

Answers

The units for molarity is moles of solute per liter of solution which means if you multiply the molarity of a solution by its volume you get how many moles of solute are in the solution. (0.75Mx0.5L=0.375mol NaCl) Then you can multiply the moles of sodium chloride (0.375 mol) by its molar mass (58.45 g/mol) to get 21.92g of sodium chloride. That means there is 21.92 grams of sodium chloride in 500mL of 0.75M solution. I hope this helps. Let me know if anything is unclear.

Hess's law ____. A) makes it possible to calculate ΔH for complicated chemical reactions B) states that when you reverse a chemical equation, the sign of ΔH does not change. C) determines the way a calorimeter works D) describes the vaporization of solids

Answers

A.)   makes it possible to calculate ΔH for complicated chemical reactions 

Hess’s Law makes it possible to calculate ΔH for complicated chemical reactions. Moreover, the principle claims that the entire amount of “enthalpy” when the development or progression of a chemical reaction is complete whether the reactions are created in a single or numerous processes, it still changes. This law is now described as the principle of conservation of energy, and part of the thermodynamics law as the first.  




How many moles of aluminum oxide can be made if 5.23 mol Al completely react

Answers

Answer:

2..615moles of Aluminium oxide

Explanation:

4Al + 3O2 -------> 2Al2O3

(5.23mol Al)×(2molaAl2O3) /(4molAl)

2.615moles of Aluminium oxide

4Al + 3O2 --> 2Al2O3

(5.23mol Al)(2mol Al2O3/4mol Al) = 2.62mol Al2O3
