What charge would an ion have if it had more electrons than protong?

A. It would be neutral, since electrons would be outside the nucleus.
B. It would have a net positive charge.
C. It would have no charge.
D. It would have a net negative charge.

Answers

Answer:

D. It would have a net negative charge

Explanation:

In an atom, there are electrons, protons and neutrons collectively called SUBATOMIC PARTICLES. The charge of an atom is determined by the number of electrons and protons in that atom. A neutral or uncharged atom possess the same number of electrons and protons.

The charge can thus be calculated as follows:

Charge of atom = no. of protons - no. of electrons.

Hence, when the number of electrons in an atom is higher than that of the protons, it means that the atom has gained negatively charged electrons, making that atom have a net negative charge. For example, In an atom that contains 10 protons and 11 electrons, the charge of that atom will be (10 - 11) = -1. The net charge of that atom will be -1, which is NEGATIVE.

1. As+H2=AsH3

2. draw a line under the problem with this:

A = 1            | A = 1

H = 2           | H = 3

3. We need everything to be equal (2x3 to get 6 then count the As on the product side to get the 2, then add 2 A on the reactant side):  

A = 2            | A = 2

H = 6           | H = 6

C and H2O

 
CO2 and H2O

 
CO2 and H​

Answers

When methane undergoes combustion the carbon dioxide (CO₂) and water (H₂O) is formed. Therefore, option C is correct.

What do you mean by combustion ?

A chemical reaction between two or more substances, usually involving oxygen, that produces heat and light in the form of a flame is called as combustion. The reaction is as follows:

CH4(g) + 2O₂(g) → CO₂(g) + 2H₂O

Methane burns in the presence of enough oxygen to produce carbon dioxide (CO₂) and water (H₂O). When it is burned, it produces a large amount of heat, making it an excellent fuel source.

Thus, option C is correct.

Calculate the equilibrium constant of the reaction below if the pressures are 1.0atm, 2.0 atm, and 1.0 atm respectively. PCl3 + Cl2 <--> PCl5

Answers

Answer:

K = 0.5

Explanation:

Based on the reaction:

PCl₃ + Cl₂ ⇄ PCl₅

The equilibrium constant, K, is defined as:

K = P PCl₅ / P PCl₃ * P Cl₂

Where P represent the pressure at the equilibrium for each one of the gases involved in the equilibrium.

As:

P PCl₅ = 1.0atm

P PCl₃ = 1.0atm

P Cl₂ = 2.0atm

K = 1.0atm / 1.0atm * 2.0atm

K = 0.5

Which salt is most soluble at 90C?

Answers

Explanation:

sodium nitrate is most soluble at 90C.

Solubility is the ability to get dissolved. The salt of sodium is the most soluble salt at 90 degrees.

What is solubility?

Solubility is the compound's or substance's ability to get dissolved in the solvent for the formation of the solution. It depends on several factors like hydration energy, temperature, pressure, and lattice energy.

The size of sodium is small, it has less lattice energy compared to the hydration energy and can get readily dissolved as it can create a sphere around other ions to form the solution.

Therefore, sodium salt is the most soluble at 90 degrees celsius.

A larger balloon has 2.5 l of nitrogen gas at 298 k . If the temperature is increased to 333 k , what will be the new volume of balloon filled with nitrogen

Answers

Answer: The new volume of baloon filled with nitrogen is 2.8 L

Explanation:

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

Mathematically,

[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

where,

[tex]V_1\text{ and }T_1[/tex] are the initial volume and temperature of the gas.

[tex]V_2\text{ and }T_2[/tex] are the final volume and temperature of the gas.

We are given:

[tex]V_1=2.5L\\T_1=298K\\V_2=?\\T_2=333K[/tex]

Putting values in above equation, we get:

[tex]\frac{2.5}{298}=\frac{V_2}{333}\\\\V_2=2.8L[/tex]

Thus the new volume of baloon filled with nitrogen is 2.8 L

A thermite reaction realeses large amounts of heat and light resulting in the melting of the iron metal

Answers

Answer:

1. Fe₂O₃ : Al = 1 : 2

2. Fe₂O₃ : Al₂O₃ = 1 : 1

3. Fe₂O₃ : Fe = 1 : 2

Note: The question is incomplete. The complete question is given below :

A thermite reaction releases large amounts of heat and light, resulting in the melting of the iron metal that forms during the reaction. The balanced chemical equation is given below: Fe₂O₃(s) + 2Al(s) ---> Al₂O₃(s) + 2Fe(l) Determine the correct mole ratios for the following substances, based on this chemical equation.

Explanation:

A thermite reaction is a highly exothermic reaction that occurs between a mixture of powdered aluminium and iron (iii) oxide.

The reaction is a redox reaction which produces aluminium oxide and metallic iron.

The heat given out in the reaction melts the iron formed. It is used to join railway tracks or cracked machine parts. The molten iron runs down between the tracks and welds them together.

The balanced equation of the reaction is given below :

Fe₂O₃(s) + 2Al(s) ---> Al₂O₃(s) + 2Fe(l) + Heat

The mole ratio of the reactant and products are as follows:

1. 1 mole of Iron (iii) oxide and 2 moles of aluminium are combined

Fe₂O₃ : Al = 1 : 2

2. 1 mole of aluminium oxide is produced from 1 mole of iron (iii) oxide

Fe₂O₃ : Al₂O₃ = 1 : 1

3. 2 moles of of iron are produced from 1 mole of iron (iii) oxide

Fe₂O₃ : Fe = 1 : 2
