Which of the following is true? Electrons are shared in ionic bonding

Answers

Answer:

The two most basic types of bonds are characterized as either ionic or covalent. In ionic bonding, atoms transfer electrons to each other. ... In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.

Explanation:

How does a sugar solution become rock candy?

Answers

Answer:

Explanation:

A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in solution—so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.

After the shuttle disaster, an unknown compound residue was removed from a piece of the debris. Upon analysis, it was found to contain 2.61 g of carbon, 6.09 g of nitrogen, and 1.31 g of hydrogen. What is its empirical formula?

Answers

Answer:

The final empirical formula is [tex]C_2 N_5 H[/tex]

Explanation:

Given

The amount of carbon, nitrogen and hydrogen in a given compound is as follows

C:N:H

[tex]2.61 : 6.09 : 1.31[/tex]

On simplifying the ration values  we get

[tex]\frac{2.61}{1.31} : \frac{6.09}{1.31} : \frac{1.31}{1.31}[/tex]

So the final ratio is

[tex]2 : 5 : 1[/tex]

The final empirical formula is [tex]C_2 N_5 H[/tex]

Explanation:

A gas in a piston starts out with a volume of 156 mL, a temperature of 28.1° C, and a pressure of 1.12 atm. If it ends with a volume of 312 mL and a temperature of 87.2° C, what is the new pressure?

Answers

Answer:

0.67atm is the new pressure of the gas

Explanation:

To find one condition of a gas when pressure, volume and absolute temperature change we must use combined gas law:

[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]

Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.

Replacing:

P₁ = 1.12atm

V₁ = 156mL

T₁ = 28.1°C + 273.15K = 301.25K

P₂ = ?

V₂ = 312mL

T₂ = 87.2°C + 273.15 = 360.35K

1.12atm*156mL / 301.25K = P₂*312mL / 360.35K

P₂ = 0.67atm is the new pressure of the gas

mass-mass problem:
If 25.0 grams of carbon dioxide are used in photosynthesis how many grams of glucose (C6H12O6) could be Produced according
to the following equation : 6CO2 + 6H2O → C6H12O6 + 602

Answers

Answer:

17.05 g of glucose

Explanation:

The equation of the reaction is given as;

6CO2 + 6H2O → C6H12O6 + 602

From the equation;

6 mol of CO2 produces 1 mol of  C6H12O6

Converting to masses;

CO2:

Mass =Number of moles * Molar mass

Mass = 6 mol * 44 g/mol = 264 g

C6H12O6:

Mass =  Number of moles * Molar mass

Mass = 1 mol * 180 g/mol = 180 g

This means 264g of CO2 produces 180g of C6H12O6

25g of CO2 would produce x g of C6H12O6

264 = 180

25 = x

x = 25 * 180 / 264

x = 17.05 g

D. individual electron

Explanation:

Every individual electron  will have its own unique set of quantum numbers.

What are quantum numbers?

Quantum numbers are the numbers which describe the values of conserved quantities with respect to the dynamics of a quantum system.They correspond to the Eigen values of operators which commute with the Hamiltonian quantities.

The Hamiltonian quantities can be known with precision simultaneously with the system's energy.Quantum numbers can take values of discrete sets of integers or even half-integers even though they can approach infinity in some cases.

They can specifically describe energy levels of electrons, and can also explain angular momentum,spin,etc.These are used to describe the path of an electron in an atom ,when the quantum numbers of all atoms are combined they must comply with the Schrodinger equation.

How many grams of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)?

Answers

Answer:

[tex]55.1657[/tex] grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)

Explanation:

The molecular weight of acetylene is  26.04 g/mol

Molecular weight of carbon is equal to 12.011 g/mol

Two carbon atom produces one acetylene molecule.

Thus, 2 * 12.011 g/mol of carbon is used to produce  26.04 g/mol of acetylene,

Amount of carbon required to produce 59.8 grams of acetylene

[tex]\frac{2*12.011}{26.04} * 59.8 \\= 55.1657[/tex]grams/mol

Given: C2H5C1
P1: 951.72 kPa
P2: 362.29 kPa
T1: 653.34 K
Wanted: kelvins?

Answers

Answer: The final temperature is 248.7 K

Explanation:

To calculate the final temperature of the system, we use the equation given by Gay lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume.

Mathematically,

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

where,

[tex]P_1\text{ and }T_1[/tex] are the initial pressure and temperature of the gas.

[tex]P_2\text{ and }T_2[/tex] are the final pressure and temperature of the gas.

We are given:

[tex]P_1=951.72kPa\\T_1=653.34K\\P_2=362.29kPa\\T_2=?[/tex]

Putting values in above equation, we get:

[tex]\frac{951.72}{653.34}=\frac{362.29}{T_2}\\\\T_2=248.7K[/tex]

Thus the final temperature is 248.7 K
