Answer:

D. Na has a larger radius than Na+ because Na+ has lost its outermost energy shell.

Explanation:

The radius is larger because the diameter of Na+ is larger.

Sodium has smaller atomic  radius than sodium cation because sodium has expanded electron cloud.

Atomic radius is defined as the  distance between outermost shell and the nucleus. Atomic radius varies across the periodic table where in groups it increases due to the fact that new shells are added on moving sown the group.

While in a period it decreases from left to right across the periodic table as electrons are added to the same shell which causes contraction of the atom.In case of comparison between an atom and a cation an atom has smaller atomic radius due to presence of electrons while in case of ions atomic radius is smaller as they have less number of electrons.

Atoms have expanded electron cloud while the electron cloud in case ions is small , the reason being the presence of large number of electrons in case of atoms and less number of electrons in case of ions.

What happens to the ionizing rate if the steps of ionizing polyprotic acid increases? Well they have this stepwise ionization process occurs for all polyprotic acids

Explanation:

Based on N:Z ratio, Zr-85 is expected to decay by positron emission. Zr-95 is expected to emit beta particles in a beta decay.

The N:Z ratio determines the stability of a nucleus. If a nucleus has  N:Z ratio >1.5 or <1.0, such a nucleus is unstable and will undergo radioactive decay. The aim of such a decay is to attain a favorable  N:Z ratio.

For Zr -85, the  N:Z ratio is 1.1 while the  N:Z ratio of Zr-95 is 1.4.  Zr -85 is expected to decay by positron emission which increases the N:Z ratio. For  Zr-95, the nucleus tends to undergo processes that decrease the  N:Z ratio such as beta emission.

Answer:

essentially through the use of keplers 3rd law comparing the proportionality of a planets squared versus cubed orbital patterns you can determine how fast a planet will orbit something and complete a full orbit

Explanation:

Kepler's Third Law: the squares of the orbital periods of the planets are directly proportional to the cubes of the semi-major axes of their orbits. Kepler's Third Law implies that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit. (from NASA)

Explanation:

Cr(s) → Cr3+(aq) + 3e-Ag+(aq) + e- → Ag(s)

To solve such this we must know the concept of chemical reaction. Therefore, the balanced  net cell reaction for the chromium-silver voltaic cell is Cr(s)+3Ag⁺(aq)→Cr³⁺(aq)+3Ag(s)

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction. Chromium-silver voltaic is a cell that is used in electrochemistry.

The balanced net cell reaction for the chromium-silver voltaic cell is

Cr(s)+3Ag⁺(aq)→Cr³⁺(aq)+3Ag(s)

Therefore, the balanced net cell reaction for the chromium-silver voltaic cell is

Cr(s)+3Ag⁺(aq)→Cr³⁺(aq)+3Ag(s)

Answer:

Copper

Explanation:

Copper has this electronic configuration.

You can count the total number of electrons

= 29

Cu is the 29 th in the periodic table.( atomic number = 29)

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the given electronic configuration represents copper element.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

The systematic distribution of electrons in the various atomic orbitals is called its electronic configuration. The atomic number of copper is 29. The electronic configuration of copper is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d¹⁰. 1,2,3 represents the number of shells and s and represents the orbitals. The superscripts represents the number of electrons in each orbitals.

Therefore, the given electronic configuration represents copper element.

By applying Charles law, the final volume of the gas is equal to 42 mL.

Given the following data:

To find the final volume of the gas, we would apply Charles law:

Charles law states that when the pressure of an ideal gas is kept constant, the volume of the gas is indirectly proportional to the absolute temperature of the gas.

Mathematically, Charles law is given by the formula;

[tex]\frac{V}{T} =k\\\\\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

Where;

Substituting the given parameters into the formula, we have;

[tex]\frac{140}{400} = \frac{V_2}{120} \\\\140 \times 120 = 400V_2\\\\16800 = 400V_2\\\\V_2 = \frac{16800}{400}[/tex]

Final volume = 42 mL.

Answer:

The periodic table, also known as the periodic table of chemical elements, is a tabular display of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry.

Explanation:

The periodic table is a tabular arrangement of chemical elements that classifies elements according to repeating qualities and is structured by increasing atomic number. Metals are located on the left side of the table, whereas nonmetals are located on the right. The columns are referred to as groupings.
