What is the order in which electrons start filling the orbitals?
a. 1s 2s 2p 3s 3p 4s 3d 4p
b. 1s 2s 2p 3s 3p 3d 4s 4p
c. 1s 2s 2p 3s 4s 3p 3d 4p
d. 1s 2s 2p 3s 4s 4p 3p 3d
e. 1s 2s 2p 3s 4s 3p 4p 3d

Answers

Answer 1

a. 1s 2s 2p 3s 3p 4s 3d 4p is the correct option.

This gives the following order to fill the orbit: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, (8s, 5g, 6f, 7d, 8p, and 9s)

Aufbau's principle states that electrons fill low-energy atomic orbitals before they fill high-energy atomic orbitals. .. By following this rule, you can predict the electron configuration of an atom or ion.

There may be two electrons at the maximum of one orbit. Since the s subplane has only one orbit, it can hold up to two electrons. The p subplane has three orbitals, so it can hold up to six electrons. The d-subplane has five orbitals, so it can hold up to 10 electrons.

A 35g chunk of metal at 130C was dropped in a bucket containing 220g of water at 25C. The final temperature of the mixture
was 300. What is the specific heat capacity of the metal?
(Specific heat for water: 4184 J/g C) Formula (m)(c)(T) = (m) (c)(T)

Answers

Answer: The specific heat capacity of metal is [tex]1.31J/g^0C[/tex]

Explanation:

[tex]Q_{absorbed}=Q_{released}[/tex]

As we know that,  

[tex]Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})[/tex]

[tex]m_1\times c\times (T_{final}-T_1)=-[m_2\times c\times (T_{final}-T_2)][/tex]      

where,

[tex]m_1[/tex] = mass of metal = 35 g

[tex]m_2[/tex] = mass of water = 220 g

[tex]T_{final}[/tex] = final temperature = [tex]30^0C[/tex]

[tex]T_1[/tex] = temperature of metal = [tex]130^oC[/tex]

[tex]T_2[/tex] = temperature of water = [tex]25^oC[/tex]

[tex]c_1[/tex] = specific heat of metal = ?

[tex]c_2[/tex] = specific heat of water =  [tex]4.184J/g^0C[/tex]

Now put all the given values in equation (1), we get

[tex]m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)][/tex]

[tex]35\times c_1\times (30-130)^0C=-[220g\times 4.184\times (30-25)][/tex]

[tex]c_1=1.31J/g^0C[/tex]

Therefore, the specific heat capacity of metal is [tex]1.31J/g^0C[/tex]

A sample of Oxygen gas is in a cylinder at constant temperature. What would happen to the pressure of the gas if the volume was
smooshed down to half its original size? Decreasing the volume by a factor of 2.

Answers

Answer:

This means that the pressure would become double of it's initial pressure.

Explanation:

Key statements:

- Constant temperature

- What happens to the pressure of the gas if the volume was

smooshed down to half its original size?

Basically the question is asking about the relationship between pressure and volume at constant temperature. This is given by Boyle's law.

Boyle's law states that the volume of a fixed mass of gas is inversely proportional to it's volume at a fixed temperature.

This is given by;

P1V1 = P2V2

Where;

P1 = Initial pressure

P2 = Final pressure

V1 = Initial Volume

V2 = Final Volume

From the question;

V2 = V1/2

Inserting it into the equation;

P1 V1 = P2 V1/2

Divide all through by  V1

P1  = P2 /2

P2 = 2 P1

This means that the pressure would become double of it's initial pressure.

What is the boiling point for butane?

Answers

Answer:

30.2°F

Butane, the liquid that can be seen inside a transparent lighter, boils at a temperature slightly under the point at which water freezes. So why doesn't the butane in the lighter boil? Butane does indeed boil at about a degree below 32 degrees Fahrenheit, but this is true only at normal atmospheric pressure. (:

Use the following chemical equation to answer the question. 4K(s) + O2(g) → 2 K2O(s). If a staff member at a laboratory has 12.0 grams of potassium metal, what is the theoretical yield of potassium oxide that the scientist could potentially produce from the reaction with oxygen gas?
A) 9.96 grams of K2O
B) 14.5 grams of K2O
C) 28.9 grams of K2O
D) 57.8 grams of K2O

Answers

Answer:14.5 grams of K2O

Explanation:

4K(s) + O2(g) → 2 K2O(s). If a staff member at a laboratory has 12.0 grams of potassium metal,  14.5 grams of K2O is the theoretical yield of potassium oxide that the scientist could potentially produce from the reaction with oxygen gas. Therefore, option B is correct.

What is theoretical yield ?

The yield of a reaction is used to represent how much of a product is produced from that reaction. The theoretical yield is the quantity of product that stoichiometry predicts will be produced, whereas the actual yield is the amount that is actually produced.

Divide the ratio by the limiting reactant's molecular weight. The answer is the theoretical yield of the desired product in moles.

It is useful to know how much product will be created with specific reactant amounts before carrying out chemical reactions. The theoretical yield is what is meant by this. This method can be applied to determine the theoretical yield of a chemical reaction.

Thus, option B is correct.

What category of organisms makes up the largest percent of the the fossils discovered? A. Land animals B. Marine animals C. Microorganisms

Answers

Answer:

Marine animals

Explanation:

A fossil is any remains of ancient life. Fossils can be body fossils, which are remains of the organism itself or trace fossils, such as burrows, tracks, or other evidence of activity(Lumen Learning).

Fossils of land animals are less common because they may not have been buried. However, land organisms may become buried underneath by mudslides or ash from a volcanic eruption, or covered by sand in a sandstorm.

Marine fossils are more common owing to quick burial. Marine animals that die near a river delta may be buried by sediment carried by the river. A storm at sea may shift sediment on the ocean floor, covering and helping to preserve skeletal remains(Lumen Learning).

The biggest error in this investigation is the use of inappropriate types of equipment.

The types of equipment used in the given setup are inappropriate. Suggested improvements in the apparatus to increase the accuracy are given below:

1. The use of a polystyrene cup in the laboratory for any reaction is inappropriate. As a slight increase in temperature causes the decomposition of the chemicals in the cup as well.

2. The use of a thermometer stand is a must. Without using the stand, the tip of the thermometer touches the lid of the container, which causes inaccuracies in the result.

A chemical reaction that is expected to form 325.0 gof product only forms 123.8 g of product. What is the percent yield of this reaction?
38.1%
61.9%
201.2%
262.5%

Answers

Answer:

[tex]\boxed {\boxed {\sf A. \ 38.1 \%}}[/tex]

Explanation:

Percent yield is the ratio of the amount actually produced to how much could theoretically be produced. It is found using this formula:

[tex]\% \ yield = \frac{actual \ yield}{theoretical \ yield} *100[/tex]

For this reaction, the theoretical or expected yield is 325.0 grams. The actual yield is 123.8 grams.

[tex]\% \ yield = \frac{ 123.8 \ g }{325.0 \ g }*100[/tex]

Divide.

[tex]\% \ yield = 0.380923077 *100[/tex]

[tex]\% \ yield = 38.0923077[/tex]

Round to the nearest hundredth. The 9 in the hundredth place tells us to round the 0 to a 1 .

[tex]\% \ yield \approx 38.1[/tex]

The percent yield is about 38.1%
