The theoretical yield of silver chloride, AgCl is 5.2109 g

The balanced equation for the reaction is given below:

<h3>3AgNO₃(aq) + AICI₃(aq) —> Al(NO₃)₃ (aq) + 3AgCl (s) </h3>

Next, we shall determine the mass of aluminum chloride, AICI₃ that reacted and the mass of silver chloride, AgCl produced from the balanced equation. This is illustrated below:

Molar mass of AICI₃ = 133.34 g/mol

Mass of AICI₃ from the balanced equation = 1 × 133.34 = 133.34 g

Molar mass of AgCl = 143.32 g/mol

Mass of AgCl from the balanced equation = 3 × 143.32 = <em>429.96 g</em>

<h3>SUMMARY</h3>

From the balanced equation above,

133.34 g of AICI₃ reacted to produce 429.96 g of AgCl.

Finally, we shall determine the theoretical yield of AgCl by the reaction of 1.616 g of AICI₃ as follow:

From the balanced equation above,

133.34 g of AICI₃ reacted to produce 429.96 g of AgCl.

Therefore,

1.616 g of AICI₃ will react to produce = \frac{1.616 * 429.96}{133.34} = 5.2109 g of AgCl.

Thus, the theoretical yield of silver chloride, AgCl is 5.2109 g

What is the element of lowest atomic number whose electronic configuration has four completely filled p sub shells
disa [49]

The element of lowest atomic number whose electron configuration has 4 completely filled p orbitals is, Xenon, Xe with electron configuration:1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶.

According to the question, we are required to identify the element with the lowest atomic number whose electronic configuration has four completely filled p sub-shells.

Evidently, the shell with energy level one has no p orbital.

  • Therefore, the existence of p orbitals in electron configuration begins with shell energy level, n=2.

  • However, we must know that the p-orbital comprises of 3 sub-orbitals namely;

p(x) , p(y) and p(z) with two electrons of opposing spin in each sub orbital.

  • Therefore, the total number of electrons in the p orbital is 6 electrons.

In essence, the element in question should have electron configuration;

  • 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶.

The electron configuration above contains 54 electrons and has atomic number, 54.

In essence, the element of lowest atomic number whose electron configuration has 4 completely filled p orbitals is, Xenon, Xe.

Equal volumes of H2 and O2 are placed in a balloon and then ignited. Assuming that the reaction goes to completion, which gas wi
nirvana33 [79]

The reaction is

2H₂(g)  + O₂(g) ---> 2H₂O

Thus as per balanced equation two moles of hydrogen will react with one moles of oxygen.

There is a directly relation between moles and volume. [One mole of each gas occupies 22.4 L of volume at STP]

Thus we can say that two unit volume of hydrogen will react with one unit volume of oxygen

Now as we have started with equal units of volume of both oxygen and hydrogen, half of oxygen will be consumed against complete volume of hydrogen

so the gas which will remain in excess is oxygen

How do I do scientific notation
lina2011 [118]
1. First, move the decimal place until you have a number between 1 and 10. If you keep moving the decimal point to the right in 0.0000073 you will get 7.3.
2. Next, count how many places you moved the decimal point.

If a gas is 0.8L at 900 mm Hg and 400K, what is the new pressure if the volume decreases to 0.5L and 300K?
mezya [45]

Answer:

The new pressure of the gas is 1080 mmHg

Explanation:

The general equation provides a way to calculate the relationship between changesnp in volume, temperature and pressure of a given mass of gas.

The general gas equation is given as P1V1/T1 = P2V2/T2

Where P1 is initial pressure of gas

V1 is initial volume of gas

T1 is initial temperature of gas

P2 is final pressure of gas

V2 is final volume of gas

T2 is final temperature of gas

From the given question, P1 = 900 mmHg, V1 = 0.8 L, T1 = 400 K, P2 = ?, V2 = 0.5 L, T2 = 300 K

Making P2 subject of the general gas equations:

P2 = P1V1T2/V2T1

P2 = (900 × 0.8 × 300) / (0.5 × 400)

P2 = 1080 mmHg

Therefore, the new pressure of the gas is 1080 mmHg.

Please tell me the answer ​
Fiesta28 [93]

Answer:

the pair of isotopes are b and e

the element with mass no of 19 is C

the element with atomic no 7is D

Explanation:

B and E are isotopes bcos they have the same atomic no, i.e no of protons. They bother have atomic no of 17 BUT have different mass no i.e sum of neutrons and protons.

(b)C is correct because the sum of the protons and neutrons is 19

(c) D because it has 7 protons
