The ionic and net ionic equation for HCl + Mg(C2H3O2)2 ⇒ MgCl2 + HC2H3O2 is H⁺ + Cl⁻ + Mg⁺ + C₂H₃O₂⁻ → Mg⁺ + Cl₂⁻ +  H⁺ + C₂H₃O₂⁻.

Ionic equations are chemical equations that only show the ions involved in a chemical reaction. In other words, ions that combine in solution to form new substances. The ions that do not participate are referred to as spectator ions.

A net ionic equation depicts only the chemical species involved in a reaction, whereas a complete ionic equation depicts the spectator ions as well.

Thus,  H⁺ + Cl⁻ + Mg⁺ + C₂H₃O₂⁻ → Mg⁺ + Cl₂⁻ +  H⁺ + C₂H₃O₂⁻ this is the net ionic equation.

Explanation:

There are numerous ways to determine whether lead is present in an ore. Atomic absorption spectroscopy is a popular approach. With this method, an ore sample is dissolved in acid and then atomized in a flame or plasma.

The sample's atoms will absorb light at particular wavelengths that are peculiar to the element under investigation. The amount of light absorbed can be used to calculate how much lead is present in the sample. Inductively coupled plasma mass spectrometry and X-ray fluorescence spectroscopy are further techniques. It is crucial to remember that these procedures call for specialized tools and training, thus they ought to only be carried out in a lab by qualified experts.

ln(s) = -4197 (1/T) + 17.96, the amount of salt that will dissolve in 5ml of water at 85°c is 25.6grams, option B.

With the equation, ln(s) = -4197 (1/T) + 17.96

Where, ln(s) = natural log of substance in solid state

T = temperature of water, 85°c = (85 + 273) to kelvin

Applying to the equation;

ln(s) = -4197 x 1/(85 + 273)) + 17.96

ln(s) = (-4197 /(358)) + 17.96

ln(s) = -11.72 + 17.96

ln(s) = 6.236, to the nearest two decimals, 6.24

s = \(e^{6.24}\) where, e is the base the natural log

s = 512.8 grams per 100ml (513, nearest whole number)

If  100ml = 513 grams,

then 5ml = (5 / 100) x 513

s = 25.64 grams/5ml

s = 26 grams

This reaction is both precipitation reaction as well as double displacement reaction.

In a double displacement reaction the anions are exchanged and in a precipitation reaction, a precipitate is formed in the end. In this case, AgCl is the precipitate.

Taking into account the definition of wavelength, frecuency and propagation speed, the wavelength of light with a frequency of 2.04×10¹⁵ Hz is 147.06 nm.

The wavelength is the minimum distance between two successive points of the wave from which the wave repeats itself.It is expressed in units of length (m).

Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

The propagation speed of a wave can be measured as the time that elapses between when it is emitted and when it is received. In other words, the speed of propagation of a wave is the magnitude that measures the speed at which the disturbance of the wave propagates along its displacement.

The propagation speed relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation:

v = f×λ

All electromagnetic waves propagate in a vacuum at a constant speed of 3×10⁸ m/s, the speed of light.

In this case, you know:

Replacing in the definition of propagation speed:

3×10⁸ m/s= 2.04×10¹⁵ Hz× λ

Solving:

λ= 3×10⁸ m/s ÷ 2.04×10¹⁵ Hz

λ= 1.4706×10⁻⁷ m= 147.06 nm (being 10⁻⁹ m= 1 nm)

In summary, the wavelength of the wave is 147.06 nm.

The volume of 12 gas forms when 21 L Cl2 react at STP is 21 L.

To determine the volume of 12 gas (I assume you mean I2 gas) formed when 21 L of Cl2 reacts at STP (standard temperature and pressure), we need to use the ideal gas law equation.

The ideal gas law equation is given by:

PV = nRT

Where:

P = pressure

V = volume

n = number of moles

R = ideal gas constant

T = temperature

At STP, the pressure is 1 atm, and the temperature is 273.15 K.

From the balanced equation, we can see that the molar ratio between Cl2 and I2 is 1:1. So, if 21 L of Cl2 reacts, it will produce an equal volume of I2 gas.

Given that the volume of Cl2 is 21 L, we can assume the volume of I2 gas formed will also be 21 L.

Therefore, the volume of I2 gas formed is 21 L.
