Salt is an ionic compound that is produced when a cation and an anion from an acid-base reaction combine, and solutions of salts

Andrej [43]

Answer:

a. True

Explanation:

The statement given regarding salt is correct,

Salt is ionic in nature, as it is composed of a positive ion, i.e. , cation and a negative ion, i.e. , anion.

Salt can be made by the combination of respective acid and base.

There are three nature of salt, acid, base and neutral.

Hence, from the given statement of the question,

The correct option is a. True.

Balance the equation and determine how many liter of nitrogen are required to react with 7.3 L of hydrogen to produce ammonia (n

Musya8 [376]

Answer:

4.867 L of ammonia

Explanation:

Using Haber's process to form ammonia using Nitrogen and hydrogen, the equation is :

N₂ + 3H₂ → 2NH₃

Here, 3 moles of hydrogen gas gives 2 moles of ammonia.

1 mole of any substance occupies 22.4L at STP

So, 3 x 22.4L of hydrogen gives 2 x 22.4 L of ammonia

Then 7.3 L of hydrogen will give:

= $\frac{7.3 \times 2 \times22.4 }{3 \times22.4}$

= $\frac{7.3 \times 2}{3}$

= 4.867 L of ammonia

Be sure to answer all parts. Consider the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g)ΔH = −198.2 kJ/mol How would the concentrations of S

andrew-mc [135]

Answer:

a)

[SO2]: The concentration increases

[O2]: The concentration increases.

[SO3]: The concentration decreases.

b)

[SO2]: The concentration decreases.

[O2]: The concentration decreases.

[SO3]: The concentration increases.

c)

[SO2]:There is no change.

[O2]: There is no change.

[SO3]: There is no change

Explanation:

For an exothermic reaction, increase in temperature decreases the concentration of products and increases the concentration of reactants since increase in temperature shifts the equilibrium position to the left hand side.

Increase in pressure and decrease in volume will shift the equilibrium position towards the right hand side which means more SO3 in the system.

Catalyst increases the rate of forward and reverse reaction simultaneously hence at equilibrium, the concentration of reactants and products remain unchanged.

How many liters of peroxide should be added to 12 liters of an 8% peroxide solution so that the remaining solution contains 16%

Nastasia [14]

The question above may be solved using the overall mass and component balances. If we let x be the number of liters of peroxide that should be added, the final mixture will have a quantity of x+12 L. The peroxide balance before and after mixing is,
x(1) + 12(0.08) = (x + 12)(0.16)
The value of x is 1.143. Thus, approximately 1.143 L of peroxide should be added to the original solution.

The balmer series is a group of spectral lines resulting from the decay of an excited electron in a hydrogen atom to what atomic

mel-nik [20]

Every line in the hydrogen spectrum that was in the visible light area had a relationship to a single number, which caught Balmer's attention. Its numeric value was 364.50682 nm. Any number more than 2 may be squared, divided by itself squared minus 4, and then multiplied by 364.50682 to obtain the wavelength of another line in the hydrogen spectrum (see the equation below). His formula predicted lines that were later discovered but had not yet been detected, allowing him to demonstrate that certain measurements of lines performed in his era using spectroscopy were somewhat off. He also turned out to be the series' capstone in terms of number.

The Balmer equation was first stated as follows (apart from a notation adjustment to provide Balmer's constant as B), and it could be used to determine the wavelength of the absorption/emission lines:

$\lambda=B\left(\frac{n^{2}}{n^{2}-m^{2}}\right)=B\left(\frac{n^{2}}{n^{2}-2^{2}}\right)$

Where

$\lambda$ is the wavelength.

B is a constant with the value of $3.6450682 \times 10^{-7} \mathrm{~m}$ or $364.50682 \mathrm{~nm}$.$

m is equal to 2

n is an integer such that $n > m$ .

What is the atomic energy level?

The set distances from an atom's nucleus where electrons may be found are referred to as energy levels (also known as electron shells).
In an atom, the small, positively charged nucleus is surrounded by smaller, negatively charged electrons.
Energy levels resemble the rungs of a ladder in several ways.

So the more about atomic energy level visit.
