The 3+ charge next to the symbol indicates a loss of 3 electrons

When atoms form ions, they lose or gain electrons. The nucleus remains intact; there is no change in the number of protons and neutrons. A loss of electrons produces a positively charged ion (a cation).

Ex= As aluminium lost 3 electrons, its ion will have a 3+ charge since the ion has 3 more positively charged protons than negatively charged electrons (ie, 13 protons, 10 electrons).

Atoms of elements which lose electrons develop a positive charge, such as the aluminium ion, Al3+ , which results when an aluminium atom loses three electrons; or the magnesium ion, Mg2+ , which results when a magnesium atom loses two electrons.

Answer:

6.0 x 10 to the power of 23

Answer:

500K

Explanation:

We use Charle's law that states that at a constant pressure the volume of a given mass of a gas varies linearly with absolute temperature of the gas.

V ∝ T

V = kT

∴ k is the proportionality constant

v/T = as it a ratio between volume and temperature the value of k would be a constant quantity.

Therefore it can be written as:

v1 / T1 = V2 / T2

Now solving the question:

V1 = 600 torr

T1 = 300 K

V2 = 1000 torr

T2 = ?

600/300 = 1000/T2

T2= (1000 x 300)/600

T2= 500 K

The correct answer is a) pH values < 7. Acids are substances that donate hydrogen ions (H+) when dissolved in water, which increases the concentration of H+ ions in the solution.

This excess of H+ ions causes the pH of the solution to decrease below 7, which is considered neutral. Therefore, solutions with pH values below 7 are acidic, while solutions with pH values above 7 are basic or alkaline.

Insolubility, lack of conductivity, and lack of reactivity with metals are not properties common to all acids. Some acids can be soluble in water, conduct electricity, or react with metals, depending on their specific chemical properties.

The outer electron in the sodium atom is in the third energy level, once this is removed the outer level of the electrons in the sodium ion is the second energy level.

There are more protons than electrons in the sodium ion which attracts the outer energy level closer to the nucleus.

The atomic radius of Ga is smaller than that of Al. This is because there are 10 first transition row elements with electrons in the inner d orbitals between Ga and Al. The inner d orbitals do not shield the nucleus effectively due to their shape and low penetration.

When the effective nuclear charge of an atom is high the electrostatic attraction is strong, pulling electrons closer together. If you look at the periodic table you can see that Cl has a smaller radius because it is to the right of the periodic table than Al.

Fundamental particles are the subatomic particles with no substructure. i.e, those particles not composed of other particles

Quarks are fundamental particles because they cannot be separated into further sub particles. These have different 'flavours': up, down, top, bottom, strange, and charm. Other fundamental particles are electrons, and the other leptons: muons, tauons, muon neutrinos, electron neutrinos, and tauon neutrinos.

On the other side, we have the bosons. These are responsible for carrying the four fundamental forces: strong nuclear force, weak nuclear force, electromagnetic force, and gravity (The gravity force particle - graviton - is only theoretical, has not been discovered yet). The fundamental particles responsible for carrying these forces, are:

photon (electromagnetic force carrier), gluon (strong nuclear force carrier), Z/W⁺/W⁻ bosons ( weak nuclear force carrier), Graviton (gravitational force) [THEORETICAL ONLY], along with the Higgs Boson (mass particle) [DISCOVERED 2012}.

Therefore a proton is not a fundamental particle and neither are neutrons. These are composed of groups of 3 quarks. A proton is a group of (up, up, down) quarks, and a neutron is a group of (up, down, down) quarks. These are also known as baryons.

The sizes of both the anode and the cathode change because the copper ions travel from the anode to the cathode. Therefore,  a solid copper appears directly beneath the anode. The number of copper ions remains the same so there is no color in the CuSO₄ solution.

Electrolytic refining can be described as a process of refining metal, especially copper by the process of electrolysis. During electrolysis,  impure metal is used as the anode and pure metal as the cathode.

The pure metal is formed at the cathode when the electrical current is applied by dissolving impure metal at the anode.

In copper refining, a block of impure copper is taken as an anode. CuSO₄   is used as a graphite-coated electrolyte along with pure copper, as a cathode. In electrolysis, CuSO₄ divides into a positive ion of copper (Cu²⁺) and sulfate (SO₄²⁻). The copper ion (Cu²⁺) travels made of pure copper where it absorbs the electrons from the cathode.

Explanation:

ΔH(total) = (m·c·ΔT)ice + (m·ΔH(f))melt'g + (m·c·ΔT)water

2182.5j = (5g)(2.092j/g·°C)(1°C) + (5g)(334.56j/g) + (5g)(4.184j/g·°C)(ΔT)

(2182.5 - 10.46 - 1672.8)j = 20.92j/°C·ΔT

ΔT = (2182.5 - 10.46 - 1672.8)j / 20.92j/°C = 23.92°C

Since the melting ice starts and ends at 0°C and is then warmed to 23.92°C then the temperature change is also the final temp of the water based upon given energy input values.

The options that would shift the equilibrium to the right are A) Increasing pressure, B) Adding PCl3 to the system, and C) Decreasing the temperature.

To determine which factors would shift the equilibrium to the right in the given reaction, we need to consider Le Chatelier's principle.

The reaction can be represented as:

PCl3 (g) + Cl2 (g) ⇌ PCl5 (g)

A. Increasing pressure:

According to Le Chatelier's principle, increasing the pressure of a system shifts the equilibrium to the side with fewer moles of gas. In this case, the reaction produces fewer moles of gas (2 moles) compared to the total moles of reactants (3 moles). Therefore, increasing the pressure would shift the equilibrium to the right.

B. Adding PCl3 to the system:

Adding more PCl3 to the system increases the concentration of the reactant. According to Le Chatelier's principle, increasing the concentration of a reactant shifts the equilibrium in the direction that consumes the reactant. In this case, the reaction consumes PCl3, so adding more PCl3 would shift the equilibrium to the right.

C. Decreasing the temperature:

For an exothermic reaction (ΔHo < 0), decreasing the temperature favors the forward reaction. Therefore, decreasing the temperature would shift the equilibrium to the right.

D. Addition of He:

The addition of an inert gas such as He does not affect the equilibrium because it does not participate in the reaction.

Therefore, the options that would shift the equilibrium to the right are A) Increasing pressure, B) Adding PCl3 to the system, and C) Decreasing the temperature.

To produce 35.5g of H2, approximately 2055.49g of NaCl is required.

To calculate the mass of NaCl required to produce 35.5g of H2, we need to determine the stoichiometry of the reaction and use the molar mass of NaCl.

The balanced equation for the reaction is:

2NaCl + 2H2O -> 2NaOH + H2

From the balanced equation, we can see that for every 2 moles of NaCl, 1 mole of H2 is produced. We can use the molar mass of H2 (2.016g/mol) to convert the given mass of H2 into moles:

moles of H2 = mass of H2 / molar mass of H2

moles of H2 = 35.5g / 2.016g/mol

moles of H2 = 17.6 mol

Since the stoichiometry of the reaction is 2 moles of NaCl to 1 mole of H2, we can set up the following ratio:

moles of NaCl / moles of H2 = 2 / 1

Rearranging the equation to solve for moles of NaCl:

moles of NaCl = (moles of H2 * 2) / 1

moles of NaCl = (17.6 mol * 2) / 1

moles of NaCl = 35.2 mol

Now, we can calculate the mass of NaCl required using the molar mass of NaCl (58.44g/mol):

mass of NaCl = moles of NaCl * molar mass of NaCl

mass of NaCl = 35.2 mol * 58.44g/mol

mass of NaCl = 2055.49g

The pressure of the gas decreases by approximately 7% if the volume of the gas is decreased by 7% and its temperature is increased by 3% due to errors in measurements.

Let us assume the initial volume of gas is V₀. According to the question, the volume of gas decreases by 7%. Therefore, the final volume of the gas is:

V = V₀ - 0.07V₀

V = 0.93V₀

Also, the temperature of the gas increases by 3%. Therefore, the final temperature of the gas is:

T = T₀ + 0.03T₀

T = 1.03T₀

Using the ideal gas law, the initial pressure of the gas can be calculated as:

P₀ = VKT₀

And the final pressure of the gas can be calculated as:

P = VKT

To find the percentage change in pressure, we can use the formula:

% Change = (New Value - Old Value)/Old Value x 100

Substituting the values of P₀, P, V₀, V, T₀, and T in the above formula, we get:

% Change = (VK(1.03T₀))(0.93V₀) - VKT₀/VKT₀ x 100

Simplifying the above expression, we get:

% Change = -7%

Option (d), P=ATC=MR=MC, accurately represents the long-run equilibrium condition for perfect competition, reflecting the balance between price and cost for firms operating in a competitive market.

The long-run equilibrium condition for perfect competition is that price (P) is equal to average total cost (ATC), which is also equal to marginal cost (MC), and marginal revenue (MR).

Option (d), P=ATC=MR=MC, best represents the long-run equilibrium condition for perfect competition. In perfect competition, firms operate at the minimum point of their average total cost curve, where price equals both average total cost and marginal cost. This condition ensures that firms are earning zero economic profit and are producing at an efficient level.

In the long run, if firms are earning economic profit, new firms will enter the market, increasing competition and driving prices down. Conversely, if firms are experiencing losses, some firms may exit the market, reducing competition and causing prices to rise. This process continues until firms reach a state where price equals average total cost, marginal cost, and marginal revenue, ensuring a long-run equilibrium.

Therefore, option (d), P=ATC=MR=MC, accurately represents the long-run equilibrium condition for perfect competition, reflecting the balance between price and cost for firms operating in a competitive market.
