Which of these elements would have an electron affinity higher than that of oxygen?


Li
Ca
Ne
C
Be

Answers

Answer 1

Answer: Ne ( Neon )

Explanation: Lithium ( Li ), beryllium ( Be ), carbon ( C ), oxygen ( O ), and neon ( Ne ), are all in Period 2 in that order. Sodium ( Na ) is in Period 3. Since electron affinities decrease as you go down, Na would have a lower electron affinity level then Li but since electron affinities increase as you go across a period, only neon is farther right then oxygen ( O ), so it would be the only one element of this group that would have a higher electron affinity than that of oxygen.

Answer 2

There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. Option C is correct option.

What is periodic table?

Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.

Periodic table help a scientist to know what are the different types of elements are present in periodic table so that they can discover the new elements that are not being discovered yet.

On going down the group electronegativity decreases. On going along the period the electronegativity increases. So, Neon lies on the extreme right of Fluorine in the same period. Neon will have more electronegativity than oxygen.

Therefore, Neon is more electronegativity than fluorine.

how is the miscibility of two liquids related to their polarity?

Answers

Answer:

The more polar the liquid, the more likely that it is miscible with water. The polarity of a liquid does not affect its miscibility with water. The less polar the liquid, the more likely that it is miscible with water. The more polar the liquid, the less likely that it is miscible with water.

Explanation:

hope it helps you

Miscibility of two liquids are directly related to their polarity. The likelihood that a liquid will mix with water increases with its polarity.

What is polarity?

Polarity is the arrangement of electrical charge among the atoms connected by a chemical bond. Because both hydrogen atoms in H2 were electrically neutral, bonds among atoms of different elements were electrically inequivalent, as opposed to bonds among identical atoms, which are electrically uniform.

The likelihood that a liquid will mix with water increases with its polarity. Liquid miscibility with water is unaffected by the polarity of the liquid. The likelihood that a liquid will mix with water increases with decreasing polarity. The likelihood that a liquid will be miscible with water decreases with increasing polarity.

Therefore, miscibility and polarity are directly related.

A fusion reaction always creates which of the following?

a A massive amount of energy.
b A massive amount of heat.
C A more massive atomic nucleus.
d A massive number of smaller nuclei.

Answers

A fusion reaction can be regarded as the type of reaction that occurs where two lighter elements come together in a type of reaction giving rise to a heavier/more massive element.

A fusion reaction always creates a more massive atomic nucleus (option c).

When the two lighter nuclei comes together in a reaction, a more heavier/massive nucleus is formed but its mass will still be less than the combined mass of the two reactant nuclei.

This also indicates that the left over mass may have been released as energy.

life as we know it could not exist without water. All the chemical reactions of life occur in an aqueous solution. Water molecules are polar and are capable of forming hydrogen bonds with other polar or charged molecules. As a result, water has the following properties:
A. H2O molecules are cohesive; they form hydrogen bonds with each other.
B. H2O molecules are adhesive; they form hydrogen bonds with polar surfaces.
C. Water is a liquid at normal physiological (or body) temperatures.
D. Water has a high specific heat.
E. Water has a high heat of vaporization (energy needed to evaporate)
F. Water's greatest density occurs at 4°C

Answers

a) At 0 C water forms ice but as mentioned above F) water's greatest density occurs at 4 C and it decreases below 4 C so ice is lighter than 4C water, thus, at 0C ice comes to surface and acts as insulator thereby preventing lower water from freezing.

The water has the following properties  H2O molecules are adhesive; they form hydrogen bonds with polar surfaces and Water is a liquid at normal physiological (or body) temperatures because of polarization.

What is polarization?

The polarization is a property by which a chemical  compound shows the dipole into its nature as one element can attract the electron and attends the partial negative charge and other is electron donating and attends the partial positive charge.

In water molecule it have the tendency to accept the electron because of oxygen electronegativity and can form the bond with hydrogen too as hydrogen donates the electron and behaves as adhesive molecule.

Therefore, H2O molecules are adhesive; they form hydrogen bonds with polar surfaces and Water is a liquid at normal physiological (or body) temperatures because of polarization are the properties of water.

When you bend, stretch, or compress an object from its natural shape, it stores Elastic potential energy.

What is elastic potential energy ?

Elastic energy is the mechanical potential energy held in a material's or a physical system's configuration as it is subjected to elastic deformation as a result of work being done on it. Elastic energy is created when objects are momentarily crushed, stretched, or otherwise deformed.

Because it is stored in the bonds between atoms of an object or substance when it is momentarily stressed, elastic energy is a type of potential energy. The object may have been stretched or compressed, causing this stress.

An object's shape may change as a result of a force operating on it. If stretched or compressed, elastic things can store elastic potential energy. This occurs, for instance, when a spring is stretched or a catapult is utilized.

Thus, option D is correct.
