What happens if an element has 3 valence electrons?

Answers

Answer 1

Answer:

If an element has 3 valence electrons, it means that it can form chemical bonds with other atoms by sharing or transferring those 3 valence electrons. The resulting compound will have a chemical formula and properties that depend on the specific elements involved in the bonding and the arrangement of the atoms in the compound. Some elements with 3 valence electrons include boron (B), aluminum (Al), and phosphorus (P). These elements are commonly found in compounds such as borax (Na2B4O7), alum (KAl(SO4)2), and phosphoric acid (H3PO4), respectively.

A) SnO2
B) H2
C) Sn
D) H2O

Answers

Answer:

SnO2

Explanation:

The limiting reactant is the reactant that runs out first during a chemical reaction.

Reactants are on the left side of the reaction, so SnO2 and H2. They tell us in the question that there is "excess" hydrogen (H2), so we know there is plenty of it, as "excess" means "more than enough." If we have more than enough hydrogen, then we know that we will run out of SnO2 first.

if the lab is cold (15° c) the melting point of acetic acid will be __________ that temperature and we will find it as a _________________.

Answers

If the lab is cold at 15°C, the melting point of acetic acid will be lower than that temperature and we will find it as a solid. Acetic acid has a melting point of 16.6°C, which means that it will remain in a solid state at 15°C.

However, if we increase the temperature, the acetic acid will eventually melt and become a liquid. It's important to note that the melting point of a substance can vary depending on the conditions, such as pressure or purity. Therefore, it's essential to control the temperature and other factors when determining the melting point of a substance accurately.
If the lab is cold at 15°C, the melting point of acetic acid, which is around 16.6°C, will be higher than that temperature. As a result, you will find acetic acid in its solid form, known as a crystalline solid, under these conditions.

How did the data from the class barometer compare to the air pressure shown in the weather report?

How did the data from the class barometer compare to the air pressure shown in the weather report?

Answers

The comparison between the class barometer data and the air pressure shown in the weather report serves as a means to evaluate the accuracy and effectiveness of the barometer's measurements.

The comparison between the data from the class barometer and the air pressure shown in the weather report revealed a correlation between the two measurements. The class barometer readings were likely taken at the same time as the weather report's air pressure measurement to ensure accurate comparison.

If the class barometer readings closely matched the air pressure indicated in the weather report, it would suggest that the barometer was functioning correctly and providing reliable measurements. This would indicate that the class barometer could be used as a reliable tool for monitoring air pressure changes.

However, if there were significant discrepancies between the class barometer readings and the air pressure reported in the weather report, it could indicate a calibration issue with the barometer or potential inaccuracies in its measurements. In such a case, it would be necessary to investigate the reasons behind the discrepancies and determine the reliability of the class barometer for future use. It helps to determine the barometer's reliability as a tool for monitoring air pressure changes in the local environment.

A solution initially has a [Ca2+] = 0.100 M and [Ba2+] = 0.100 M Sulfate ion (SO42-) is being added to selectively precipitate out the Ba2+ ions and leave behind the Ca2+ ions. (The barium ions will start to precipitate out first because barium sulfate is less soluble than calcium sulfate.) BaSO4 Ksp = 1.07 x 10-10 CaSO4 Ksp = 7.10 x 10-5 Assume that somehow the sulfate ion is being added in a manner that does not change the volume of the solution significantly.

a) At what concentration of sulfate ion would the Ca2+ begin to precipitate out as calcium sulfate?

b) At that concentration of sulfate ion what would be the concentration of Ba2+ ion?

Answers

The concentration of sulfate ion would be required for Ca⁺ to begin to precipitate out as calcium sulfate is 7.10 * 10⁻⁴ M.

b) The concentration of the Ba²⁺ ion would be 9.929 * 10⁻² M

What concentration of sulfate ion would be required for Ca⁺ to begin to precipitate out as calcium sulfate?

The precipitation of calcium sulfate occurs when the ionic product, Kip is greater than or equal to the solubility product, Ksp of calcium sulfate.

Kip ≥ Ksp  

a) The equation of the dissociation of CaSO₄ is given below:

CaSO₄ ⇄ Ca²⁺ + SO₄²⁻

Ksp = [Ca²⁺] * [SO₄²⁻] = 7.10 * 10⁻⁵

Kip = [Ca²⁺] * [SO₄²⁻]

[SO₄²⁻] = Kip/[Ca²⁺]

[Ca²⁺] = 0.100 M

For precipitation to occur;

Kip = Ksp = 7.10 * 10⁻⁵

[SO₄²⁻] = 7.10 * 10⁻⁵/0.100

[SO₄²⁻] = 7.10 * 10⁻⁴ M

Therefore, the concentration of sulfate ion would be required for Ca⁺ to begin to precipitate out as calcium sulfate is 7.10 * 10⁻⁴ M.

b) The concentration of the Ba²⁺ ion would be;

0.100 M - 7.10 * 10⁻⁴ M = 9.929 * 10⁻² M

Calculate the volume percentage of phase present in an alloy of
16% by weight silicon and 84% by weight aluminium. Given density of
Si = 2.35 gm/cc and density of aluminium = 2.7 gm/cc

Answers

The volume percentage of silicon in the alloy is approximately 38.2%.

To calculate the volume percentage of silicon in the alloy, we need to consider the weight percentage and the densities of silicon and aluminium.

First, we calculate the volume of each component in the alloy based on their weight percentages. Since the density is defined as mass per unit volume, we can use the weight percentage to determine the mass of each component. For example, in 100 grams of the alloy, we have 16 grams of silicon and 84 grams of aluminium.

Next, we calculate the volume of silicon and aluminium by dividing their respective masses by their densities. Using the density of silicon (2.35 gm/cc), we find that the volume of silicon is approximately 6.81 cc. Similarly, using the density of aluminium (2.7 gm/cc), we find that the volume of aluminium is approximately 31.11 cc.

Finally, we calculate the volume percentage of silicon in the alloy by dividing the volume of silicon by the total volume of the alloy (sum of the volumes of silicon and aluminium) and multiplying by 100. In this case, the volume percentage of silicon in the alloy is approximately 38.2%.

El volumen de un gas en un recipiente cerrado es de 3.5 litros a una temperatura de 25oC y una atmósfera constante de presión. ¿ Cuál es el volumen del gas en el recipiente si se disminuye la temperatura a 7oC?

Answers

Answer:

El volumen del gas en el recipiente es 3.29 L si se disminuye la temperatura a 7°C

Explanation:

La Ley de Charles es una ley de los gases que relaciona el volumen y la temperatura de una cierta cantidad de gas a presión constante.

Esta ley establece que el volumen es directamente proporcional a la temperatura del gas. Es decir que si la temperatura aumenta, el volumen del gas aumenta, mientras que si la temperatura del gas disminuye, el volumen disminuye.

Matemáticamente, si la cantidad de gas y la presión permanecen constantes, el cociente entre el volumen y la temperatura siempre tiene el mismo valor:

\(\frac{V}{T}=k\)

Suponiendo un cierto volumen de gas V1 que se encuentra a una temperatura T1 al comienzo del experimento, al variar el volumen de gas hasta un nuevo valor V2, entonces la temperatura cambiará a T2, y se cumplirá:

\(\frac{V1}{T1}=\frac{V2}{T2}\)

En este caso, sabes:

V1= 3.5 LT1= 25 °C=298 °K (siendo 0°C=273°K)V2=?T2=7 °C=280 °K

Reemplazando:

\(\frac{3.5 L}{298 K}=\frac{V2}{280 K}\)

Y resolviendo obtienes:

\(V2=280 K*\frac{3.5 L}{298 K}\)

V2= 3.29 L

The lattice constant of Ge at room temperature is a=5.65×10 −8 cm. Detcrmine the number of Ge atoms /cm 3 . B. Calculate the distance from the center of one Germanium atom to the center of its nearest neighbor. C. The density of valence electrons /cm ∧ 3

Answers

A. The number of Ge atoms/cm is 5.54 × 10²⁴.

B. The distance from the centre of one Germanium atom to the centre of its nearest neighbour is 2.825 × 10⁻⁸cm.

C. The density of valence electrons /cm³ is 7.07 × 10⁷.

To determine the number of Germanium (Ge) atoms per cm³, we can use the lattice constant and the assumption that the Ge crystal structure forms a simple cubic lattice.

a. The volume of the unit cell in a simple cubic lattice is given by the cube of the lattice constant:

Volume of unit cell = a³ = (5.65 × 10⁻⁸ cm)³

                                  a³ = 180.36 × 10⁻²⁷

Since each unit cell contains one Ge atom, the number of Ge atoms per cm³ is equal to the reciprocal of the volume of the unit cell:

Number of Ge atoms/cm³ = 1 / (a³ = 1 / [(5.65 × 10⁻⁸ cm)³]

                                           = 0.00554447 × 10²⁷

                                           = 5.54 × 10²⁴

b. The distance from the centre of one Ge atom to the centre of its nearest neighbour can be determined by considering the arrangement of atoms in the simple cubic lattice. In this case, each Ge atom has six nearest neighbours, located at the corners of a cube surrounding the central atom.

The distance from the centre of one atom to the centre of its nearest neighbour is equal to half the length of the edge of the cube:

Distance to nearest neighbor = a / 2 = (5.65 × 10⁻⁸ cm) / 2

                                                             = 2.825 × 10⁻⁸cm

c. The density of valence electrons per cm³ can be calculated by multiplying the number of Ge atoms per cm (determined in part a) by the number of valence electrons per Ge atom. Germanium has four valence electrons.

The density of valence electrons/cm³ = Number of Ge atoms/cm³ × Number of valence electrons per Ge atom

Density of valence electrons/cm³ = (1 / [(5.65 × 10⁻⁸ cm)³]) × 4

                                                        = 7.07 × 10⁷

3) The oxidation number of bromine (Br) in KBr is -1.

4) The oxidation number of bromine (Br) in HBrO is +1.

What is the oxidation state?

The assumption that the oxidation numbers of all the atoms in a compound add up to zero is based on the principle of charge balance, where the sum of positive and negative charges should cancel out to maintain overall neutrality in the compound.

1) Since carbon (C)  in\(CBr_{4}\)has an oxidation number of +4, it is less electronegative than bromine (Br).

2) In Br\(F_{5}\), fluorine (F) has an oxidation number of -1 because it is more electronegative than bromine (Br).

3)  The oxidation number of bromine (Br) in KBr is -1. This is because the bromine atom accepts an electron

4) The oxidation number of bromine (Br) in HBrO is +1. This is from the sum of the oxidation numbers of each element.
