Answer:

In our case, the equation  2KI + F2 → 2 KI + I2 is a single-replacement (also called single- displacement) reaction.

Explanation:

<u>Step 1:</u> The balanced equation:

2KI + F2 → 2 KI + I2

<u>Step 2</u>: What kind of reaction

Since we start with 2 reactants and end with 2 products, we can say it won't be a synthesis or decomposition reaction.

In our case, It looks like it's a replacement reaction.

- A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a single-replacement reaction is:  A+BC→AC+B

where element  A  is a metal and replaces element  B , also a metal, in the compound.

When the element that is doing the replacing is a nonmetal, it must replace another nonmetal in a compound.

- A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement reaction is:  AB+CD→AD+BC

In our case, the equation  2KI + F2 → 2 KI + I2 is a <u><em>single-replacement</em></u> (also called single- displacement) reaction.

Select the name of the element with a condensed ground-state electron configuration of [kr] 5s14d7.
Vilka [71]

elements have equal number of protons and neutrons

the condensed format is when the closest noble gas with the closest electron configuration is given, this closest noble gas atomic number should be lesser than the atoms atomic number

atomic number of Kr is 36

1 electron in 5s subshell and 7 electrons in 4d subshell.

there's a total of 36 + 1 + 7 = 44 electrons

atomic number of the atom is 44

element with atomic number 44 is Ruthenium - Ru

answer is Ru

A biochemical engineer isolates a bacterial gene fragment and dissolves a 10.0-mg sample in enough water to make 30.0 mL of solu
Novay_Z [31]

The molar mass of the gene fragment is 19182 g/mol.

What is osmotic pressure ?

Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in a pure solvent by osmosis. Potential osmotic pressure is the maximum osmotic pressure that could develop in a solution if it were separated from its pure solvent by a semipermeable membrane.

We employ the osmotic pressure equation to determine the solute's concentration, which is:

π = iMRT

Using the values in the equation above, we obtain:  19182 g/mol.

Consider the elements: Na, Mg, Al, Si, P.
Olegator [25]

Answer:

The elements mentioned in the series are Na, Mg, Al, Si, and P. It can be seen that all these elements are located in the same period. The atomic number of the mentioned elements are Na-11, Mg-12, Al-13, Si-14, and P-15.

a) There will be an increase in the ionization energy with the increase in the element's atomic number across a period. More energy is needed to withdraw an electron from a completely occupied shell in comparison to an incompletely occupied shell.

The atomic number of Na is 11. When one electron is withdrawn from Na, it gets converted into the inert gas configuration of Ne. Thus, it will require more energy to withdraw the second electron from Na. Hence, Na exhibits the lowest second ionization energy.

b) Across the period, with an increase in the element's atomic number, the atomic radii reduces from left to right. Thus, P exhibits the smallest atomic radius.

c) The metallic nature of the elements reduces from left to right across a period in the periodic table. Thus, P is the least metallic element.

d) Diamagnetic signifies towards the element that exhibits pair electrons in its sub-shells. The electronic configuration of Mg is,

1s2 2s2 2p6 3s2

In Mg, no unpaired electrons are present, while all the remaining elements mentioned exhibit unpaired electrons in their valence shell. Thus, Mg is the diamagnetic element.
