what is the electronic structure of an atom with a proton number 11 and mass number 23

Answers

Answer:

1s^2 2s^2 2p^6 3s^1

Explanation:

electron configuration of an element gives description of the distribution of electron in it's orbital of the atom, the superscript symbolize number of electron been hold by them.

The element here is sodium, which is a alkali metal

mass number =23

Number of proton= 11

electron must be seen in thelowest-energy subshell that is available in the the 3s orbital,

Hence, the electronic configuration is

1s^2 2s^2 2p^6 3s^1

1. What are the differences between lonic and covalent bonds?

Answers

Answer: Ionic bonds result from transfer of electrons, whereas covalent bonds are formed by sharing. ... Ionic bonds are electrostatic in nature, resulting from that attraction of positive and negative ions that result from the electron transfer process; charge separation between covalently bonded atoms is less extreme.

Explanation:

PLEASE Answer asap! Compare two periodic families below. You must include at least two facts about each family. You may use any description of properties or periodic trends to help you.

Answers

Answer:

The alkali metals/group 1 are recognized as a group and family of elements. These elements are metals. Sodium and potassium are examples of elements in this family. Hydrogen is not considered an alkali metal because the gas does not exhibit the typical properties of the group. The largest family of elements consists of transition metals/group 3-12/group 3a. The center of the periodic table contains the transition metals, plus the two rows below the body of the table (lanthanides and actinides) are special transition metals. Even though both are metals, transition metals have higher melting points; they have higher density; they are less reactive with water; they react and form ions with different charges, but Group 1 metals only form 1+ ions.

a solution is prepared by dissolving 55g of CaCl2 into 300g of water. if the Kf of water is -1.86 c/m, shat is the freezing point depression of the solution

Answers

Relation between , molality and temperature is as follows.

                T =

It is also known as depression between freezing point where, i is the Van't Hoff factor.

Let us assume that there is 100% dissociation. Hence, the value of i for these given species will be as follows.

         i for  = 3

          i for glucose = 1

          i for NaCl = 2

Depression in freezing point will have a negative sign. Therefore, d

depression in freezing point for the given species is as follows.

       

                 =

       

                  =

Answers

The given question is incomplete. the complete question is:

The electron arrangement ions [tex]X^{3+}[/tex] and [tex]Y^{2-}[/tex] are 2, 8, and 2, 8, 8 respectively.

Write the electronic arrangement of the elements X and Y.

Write the formula of the compound that would be formed between X and Y.

Answer: 1. The electronic arrangement for X and Y are 2,8, 3 and 2,8,5 respectively.

The formula of the compound formed is [tex]X_2Y_3[/tex]

Explanation:

Electronic configuration is the arangement of electrons in an atom in order of increasing energies.

Cations are formed when electrons are lost by atoms and anions are formed when electrons are gained by atoms.

[tex]X^{3+}:2,8[/tex]

[tex]X:2,8,3[/tex]

[tex]Y^{3-}:2,8,8[/tex]

[tex]Y:2,8,5[/tex]

For formation of a neutral ionic compound, the charges on cation and anion must be balanced.

Here element X is having an oxidation state of +3 called as [tex]X^{3+}[/tex] cation and [tex]Y^{2-}[/tex] is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral [tex]X_2Y_3[/tex]

A gas at a temperature of 300 K occupies a 5 L flexible container at a pressure of 150 kPa. What volume will it occupy at STP?

Answers

6.73 L

This one requires the combined gas law.

P1V1/T1 = P2V2/T2

P1 = 150 kPa = 1.48 atm

V1 = 5 L

T1 = 300 K

P2 = 1 atm

V2 = This is what we’re solving for.

T2 = 273 K

P2 and T2 are based on the conditions of STP. I also changed P1 to atm to keep the units consistent.

Solve the equation for V2:

V2 = P1V1T2 / T1P2

V2 = (1.48 atm)(5 L)(273 K) / (300 K)(1 atm) = 6.73 L

Would a rollercoaster have the greatest kinetic energy at the top of the highest hill or at the bottom on the highest hill

Answers

Answer:

The rollercoaster has the lowest kinetic energy at the top of the hill.

The rollercaoster has the highest kinetic energy at the bottom of the hill.

Explanation:

The kinetic energy of any solid body in motion is usually computed using this formula:

K.E = [tex]\frac{1}{2}mv^2[/tex]

From this, we can see that it varies based on two major parameters - The mass of the moving object and the velocity of the moving object.

We can assume that the mass of the rollercoaster is constant since no one gets off and it does not shrink in its size during the ride.

This means that the variations in the K.E are mainly coming from its velocity.

At the top of the hill, the rollercoaster is moving at its slowest pace. hence, it has the lowest kinetic energy at the top of the hill.

However, at the bottom of the hill, the rollercoaster is moving its fastest, hence it has the highest kinetic energy at the bottom of the hill.

Calcule el volumen de disolución de LiOH a 3.5 M, necesario para neutralizar una disolución de 25 ml de H2SO3 cuya densidad es de 1.03 g/ml y su riqueza del 60%. (60 PTS.) Alguien puede ayudarme con esto porfabor

Answers

Respuesta:

0.11 L

Explicación:

Paso 1: Escribir la ecuación balanceada

2 LiOH + H₂SO₃ ⇒ Li₂SO₃ + H₂O

Paso 2: Calcular la masa de solución de H₂SO₃

25 mL de solución de H₂SO₃ tiene una denisdad de 1.03 g/mL.

25 mL × 1.03 g/mL = 28 g

Paso 3: Calcular la masa de H₂SO₃ en 26 g de Solución de H₂SO₃

La riqueza de H₂SO₃ es 60%, es decir, cada 100 g de solución hay 60 g de H₂SO₃.

26 g Sol × 60 g H₂SO₃/100 g Sol = 16 g H₂SO₃

Paso 4: Calcular los moles correspondientes a 16 g de H₂SO₃

La masa molar de H₂SO₃ es 82.07 g/mol.

16 g × 1 mol/82.07 g = 0.19 mol

Paso 5: Calcular los moles de LiOH que reaccionan con 0.19 moles de H₂SO₃

La relación molar de LiOH a H₂SO₃ es 2:1. Los moles de LiOH que reaccionan son 2/1 × 0.19 mol = 0.38 mol.

Paso 6: Calcular el volumen de solución de LiOH

0.38 moles de LiOH están en una solución 3.5 M. El volumen requerido es:

0.38 mol × 1 L/3.5 mol = 0.11 L

1.What is the coefficient of the scientific notation answer? 2.What is the exponent of the scientific notation answer? 3.How many significant figures are there in the answer ?
4.What is the right most significant figure in the answer?

Answers

Answer: 1. The coefficient is 1.12

2. The exponent is 4

3. There are 3 significant digits

4. The rightmost significant figure is 2.

Explanation:

Scientific notation is defined as the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example : 5000 is written as [tex]5.0\times 10^3[/tex]

According to avogadro's law, 1 mole of every gas contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles and occupy 22.4 L at STP.

[tex]6.023\times 10^{23}[/tex] molecules of [tex]CO_2[/tex] occupy = 22.4 L at STP.

Thus [tex]3.00\times 10^{26}[/tex] molecules of [tex]CO_2[/tex] occupy = [tex]\frac{22.4}{6.023\times 10^{23}}\times 3.00\times 10^{26}=11.2\times 10^3 L[/tex] at STP.

Scientific notation = [tex]1.12\times 10^4L[/tex]

The coefficient is 1.12

The exponent is 4

There are 3 significant digits

The rightmost significant figure is 2.
