Which group tends to have the highest ionization energy? The lowest?a) Halogens; Alkaline earth metals
b) Alkali metals; Noble gases
c) Noble gases; Alkali metals
Answers
Final answer:
The group with the highest ionization energy is(option c) noble gases due to their full electron shell, making it difficult to remove an electron. The group with the lowest ionization energy is(option c) alkali metals because they have only one electron in their outermost shell, which can be easily removed.
Explanation:
The answer to the question is (c) Noble gases; Alkali metals. Ionization energy is the energy required to remove an electron from an atom or ion. A higher ionization energy means it is harder to remove an electron.
Noble gases have the highest ionization energies because they have a full electron shell, so they do not readily give up an electron. On the other hand, alkali metals have the lowest ionization energy, because they have only one electron in their outer shell, which is relatively easy to remove.

(2) A has a high melting point, and B has a low melting point.
(3) A dissolves in water, and B does not dissolve in water.
(4) A does not burn in air, and B does burn in air.
Answers
Final answer:
The correct option is 4.
The ability of a compound to burn in air is a chemical property and can be used to distinguish between two compounds.
Explanation:
The statement that describes a chemical property which can be used to distinguish between compound A and compound B is: (4) A does not burn in air, and B does burn in air. Physical properties like color, melting point, and solubility (options 1, 2, and 3) are characteristics that can be observed without changing the substance into another substance. On the other hand, a chemical property describes how a substance interacts with other substances, including its flammability. Therefore, the ability or inability of a compound to burn in air would be a chemical property.

Since Destiny is mostly interested in higher return, he will hence most likely invest in bonds with very high risk rate. Hence, Destiny will most likely be interested in Junk bond.
- Both Municipal and savings bond are usually backed up by the government as as such they are safer to invest in. However, they have low rate of return.
- Corporate bonds are usually issued by profit - oriented companies and organizations and have a higher rate of return than municipal and savings bond.
- Junk bonds are a form of corporate bond with veryhigh level of risk which is compensated by a very high return rate compared to other corporate bonds. There is a higher tendency that companies that issue junk bonds will default on their debt.
Therefore, Destiny will most likely be interested in a Junkbond.

Explanation:
A solution with pH less than 7 will be acidic in nature and it will change color of blue litmus into red.
For example, HCl is a strong acid as it dissociates to give hydrogen ions and chlorine ions.
A solution with pH more than 7 will be basic in nature and it will change color of red litmus into blue.
A solution with pH equal to 7 will be neutral in nature and it will not change the color any litmus paper.
Thus, we can conclude that in a 0.01 M solution of HCl, litmus will be red.

X milliliters (=X/1000 liters) of a 0.171M solution contain 0.171*X/1000 moles of NaCl.
0.171*X/1000 moles of NaCl = 58.3*0.171*X/1000 g = 1 g (as given)
58.3*0.171*X/1000 = 1
X = 100.3
