The component with the most low atomic number that contains a total d-subshell in the ground state is copper. Copper's electron arrangement is [Ar]3d104s1 [ A r ] 3d 10 4 s 1 .  

Further Explanation:  

atomic number:  

The nuclear number or proton number (image Z) of a synthetic component is the quantity of protons found in the core of a particle. It is indistinguishable from the charge number of the core. The nuclear number particularly distinguishes a compound component. In an uncharged iota, the nuclear number is likewise equivalent to the quantity of electrons.

atomic number speak to:  

The nuclear number (otherwise called the proton number) is the quantity of protons found in the core of an iota. It is customarily spoken to by the image Z. The nuclear number exceptionally distinguishes a substance component. In a particle of impartial charge nuclear number is equivalent to the quantity of electrons.  

Meaning of subshell:  

A subshell is a subdivision of electron shells isolated by electron orbitals. Subshells are marked s, p, d, and f in an electron design.

The element that contains a complete d subshell in the ground state : <u>Cu</u>

<h3>Further explanation </h3>

In an atom, there are energy levels in the shell and sub shell.

This energy level is expressed in terms of electron configurations.

Writing the electron configuration starts from the lowest to the highest subshell's energy level (following Aufbau rules)

Electron filling in subshells using the following sequence

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.

And the element whose electron configuration occupies the sub shell d lies in the transition group or group B in the periodic system

Electrons can move the shell up or down by releasing energy or absorbing energy

So it can be concluded that there are 2 conditions:

Ground state is the state of electrons filling shell with the lowest energy levels.

Excited state is the state of electrons which occupies a higher energy level

In filling electrons in subshell d there are half-full and full rules because of the tendency of electrons to get stability (not following the Aufbau rule)

Example

Cr atomic number 24: [Ar] 4s² 3d⁴ [Ar] 4s¹ 3d⁵

Cu atomic number 29: [Ar] 4s² 3d⁹ [Ar] 4s¹ 3d¹⁰

Mo atomic number 42: [Cr] 5s² 4d⁴ [Cr] 5s¹ 4d⁵

So the element of the lowest atomic number that contains a complete subshell in the ground state has an electron configuration

1s², 2s², 2p⁶, 3s², 3p⁶, 4s¹, 3d¹⁰

which is owned by the element Cu

The density of ethanol is 0.789 g/mL. If you need 460.0 g of ethanol for an experiment, how many milliliters would you measure o
4vir4ik [10]

Answer:

The volume is 583.02 mL

Explanation:

Given that the density is:-

\rho=0.789\ g/mL

The mass, m=460.0\ g

The expression for the calculation of density is shown below as:-

\rho=\frac{m}{V}

Using the above expression to calculate the volume as:-

V=\frac{m}{\rho}

Applying the values to calculate the volume as:-

V=\frac{460.0\ g}{0.789\ g/mL}=583.02\ mL

<u>The volume is 583.02 mL.</u>

If the value of kc at 25oc is 3.7108, and the equilibrium concentrations for n2 and h2 are 0.000105 m and 0.0000542 m, respectiv
frez [133]

Equation of decomposition of ammonia:

N2+3H2->2NH3

Euilibrium constant:

Kc=(NH3)^2/((N2)((H2)^3))

As concentration of N2=0.000105, H2=0.0000542

so equation will become:

3.7=(NH3)^2/(0.000105)*(0.0000542)^3

NH3=√(3.7*0.000105*(0.0000542)^3)

NH3=7.8×10⁻⁹

So concentration of ammonia will be 7.8×10⁻⁹.

When heated, KClO3 decomposes into KCl and O2. 2KClO3⟶2KCl+3O2 If this reaction produced 17.4 g KCl, how many grams of O2 were p
navik [9.2K]

Answer:

12.6 g O2 or

12.60 g O2 (if needed two decimal places)

Explanation:

First convert grams into moles:

17.4 g KCl × <u> </u><u> </u><u> </u><u> </u><u> </u><u>1</u><u> </u><u> </u><u> </u><u> </u><u> </u>

74.55

= 0.233 moles of KCl

Next solve for the mole of O2:

= 0.233 × <u>3</u><u> </u><u>m</u><u>o</u><u>l</u><u>e</u><u>s</u><u> </u><u>o</u><u>f</u><u> </u><u>O</u><u>2</u>

2 moles of KCl

= 0.3495 or

= 0.350 moles of O2

Finally convert the mole to grams:

= 0.350 moles of O2 × <u> </u><u> </u><u> </u><u>36</u><u>g</u><u> </u><u> </u>

1 mole

= 12.6 g O2 or 12.60 g O2
