Answer: The correct relationship of these elements regarding their ionization energy is Strontium < Calcium < Beryllium.

Explanation:

The amount of energy required to remove the most loosely bound electron in an atom is called ionization energy.

Larger is the size of an atom, more easily it can lose an electron. Since the size of atoms increases on moving down in a periodic table so ionization energy decreases down the group.

For example, beryllium, calcium, and strontium are elements of group 2. Strontium is the largest in size and beryllium is the smallest in size.

Hence, the ionization energy of group 2 elements in the increasing order is as follows.

Strontium < Calcium < Beryllium

Thus, we can conclude that the correct relationship of these elements regarding their ionization energy is Strontium < Calcium < Beryllium.

Answer:

2.8 L

Explanation:

From the question given above, the following data were obtained:

Number of mole (n) = 0.109 mole

Pressure (P) = 0.98 atm

Temperature (T) = 307 K

Gas constant (R) = 0.0821 atm.L/Kmol

Volume (V) =?

The volume of the helium gas can be obtained by using the ideal gas equation as follow:

PV = nRT

0.98 × V = 0.109 × 0.0821 × 307

0.98 × V = 2.7473123

Divide both side by 0.98

V = 2.7473123 / 0.98

V = 2.8 L

Thus, the volume of the helium gas is 2.8 L.

Answer:

The specific shape that an electron moves in inside a sub-level shell.

Answer:

reduced; oxidized

Explanation:

An electron transport chain can be defined as a series of redox reactions (electron transporters or proton complexes) that are saddled with the responsibility of transferring electrons from electron donors to electron acceptors through a membrane in order to produce a protein gradient that creates energy or adenosine triphosphate (ATP).

Generally, as these electrons are transferred through the electron transport chain, the molecules are first reduced as they pick up electrons, and then oxidized as they release the electrons.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Answer: The statement conjugate base of hydrofluoric acid is weaker than that of acetic acid is most likely true.

Explanation:

A strong acid upon dissociation gives a weak conjugate base. This can also be said as stronger is the acid, weaker will be its conjugate base or vice-versa.

Hydrofluoric acid is a strong base as it dissociates completely when dissolved in water.

For example, [tex]HF \rightleftharpoons H^{+} + F^{-}[/tex]

The conjugate base is [tex]F^{-}[/tex] which is a weak base.

Acetic acid is a weak acid as it dissociates partially when dissolved in water. So, the conjugate base of acetic acid is a strong base.

[tex]CH_{3}COOH \rightarrow CH_{3}COO^{-} + H^{+}[/tex]

Thus, we can conclude that the statement conjugate base of hydrofluoric acid is weaker than that of acetic acid is most likely true.

Answer:

The average atomic mass includes all of the isotopes of that atom which exist in nature. Almost all elements have at least two isotopes which naturally occur. Recall that isotopes are atoms with the same atomic number (protons), but a different number of neutrons.

Answer:

7.827s

Explanation:

Given that

Height of the Eiffel tower is (h) =300.5m

Acceleration due to gravity (g) =9.81m/s2

From the kinematic equations

s =ut+(1/2)gt2

It is free fall then u =0

Then h =(1/2)gt2

Then the time taken for the croissant dropped before it tagged you on the head. is t =Sqrt(2h/g) =Sqrt(2*300.5/9.81)=7.827s

Answer: Carbon dioxide is the main cause of human-induced climate change. ... Some, such as nitrous oxide, are long-lived greenhouse gases like carbon dioxide, and so contribute to long-term climate change. Other substances have shorter atmospheric lifetimes because they are removed fairly quickly from the atmosphere.

The dissolving salt in water is an an example of a chemical change. The correct option is A.

A chemical change, also known as a chemical reaction, is the production of new substances with changing chemical compositions and characteristics.

In water, sodium chloride dissociates into Na+ ions and Cl- ions, which may be described as a chemical process.

The ionic connections between the atoms are broken as salt dissolves. Because the reactant (sodium chloride or NaCl) varies from the products (sodium and chloride ions), a chemical reaction takes place.

Thus, the correct option is A.

Answer:

Ca + Pb(NO3)2 → Pb + Ca(NO3)2

Explanation:

This is an oxidation-reduction (redox) reaction:

PbII + 2 e- → Pb0

(reduction)

Ca0 - 2 e- → CaII

(oxidation)

Pb(NO3)2 is an oxidizing agent, Ca is a reducing agent.

Which statements are consistent with Dalton's atomic theory as it was originally stated? Why?

a. Sulfur and oxygen atoms have the same mass.

b. All cobalt atoms are identical.

c. Potassium and chlorine atoms combine in a 1:1 ratio to form potassium chloride.

d. Lead atoms can be converted into gold.

Answer: The correct options are b) and c).

Explanation:

Some of the postulates of Dalton's atomic theory are:

For the given options:

For a:

The statement is inconsistent with the theory as no two elements can have the same mass. Only atoms of the same element can have the same mass.

This is consistent with the theory as atoms of the same element are identical.

This is consistent with the theory as atoms combine in a simple whole number ratio.

The statement is inconsistent with the theory as atoms of one element cannot be changed to atoms of other element.

Hence, the correct options are b) and c).

Cu(s) + Ni(NO3)2(aq) ⇒Ni(s) + Cu(NO3)2(aq)

The answer is option B.

Answer;

P4O10 - molecular solid

Graphite - network solid

Ammonium phosphate - ionic

Brass - metallic

SiC - network solid

Rb- metallic

I2 - molecular

LiBr- ionic

P4 - molecular

Plastic - amorphous

Si - network

Explanation:

An ionic solid is consists of a combination of two oppositely charged ions to yield a crystal lattice such as LiBr.

A covalent solid is one in whom the atoms of the molecule are held together by covalent bonds e.g I2.

Metals are held together by interaction of metal ions and a sea of electrons. This is called the metallic bond. Like SiC

A network solid consists of covalently bonded atoms held together by strong covalent bonds and the molecules in the solid state are held together by a continuous network of atoms.
