What would happen to our solar system if the Sun had an even greater mass than it currently does?

Answers

Answer: If the Sun had an even greater mass then it currently does, it would have a larger gravitational pull and since it's heat would be closer to Earth, both by magnitude and gravity, life on Earth wouldn't be possible and life on Mars would be reality. Also, when the sun would explode, it would have a larger supernova and possibly create a white dwarf (something that only happens to red supergiant stars when they die), with a gravitational force so strong it wold have two beams of light coming out it's north and south poles (like a black hole).

what is the molarity of a solution with 130g of CoCl2 in 1/2 liter? (can you show the steps please)

Answers

Answer:

2M

Explanation:

M=mol/L

1. Find moles of CoCl2

mass of substance/molar mass = 130/129.833 = 1.001 mol

3. Substitute in molarity equation

M=(1.001/0.5)

M= around 2M

The molarity of a solution with 130g of CoCl2 in 1/2 liter is 2M

HOW TO CALCULATE MOLARITY:

The molarity of a solution can be calculated by dividing the number of moles of that substance by its volume:

Molarity = no. of moles ÷ volume

First, we convert 130g of CoCl2 to moles as follows:

Molar mass of CoCl2 = 129.84 g/mol

moles = 130g ÷ 129.84g/mol

moles of CoCl2 = 1mol

Molarity of CoCl2 solution = 1mol ÷ 0.5L

Molarity of CoCl2 = 2M

Therefore, the molarity of a solution with 130g of CoCl2 in 1/2 liter is 2M.

elements have similar characteristics?
Periodic TaBle
oF The Elements

Answers

Answer:

See attachment.

Explanation:

Elements that are in the same group will definitely possess similar characteristics because they tend to have the same valence electron which determines their reactivity.

On a periodic table, elements in the same group can be found arranged on the same column in the periodic table.

Therefore the two elements that have similar characteristics are those two elements you can see on the same column in group 2. See the two elements indicated in the attachment below.

Answers

A 180,sp is da answer

The bond angles around carbon in the triple bond are 180 degrees and it is sp hybridized. option B is correct

What is sp hybridization?

This hybridization process involves mixing the valence s orbital with one of the valence p orbitals to yield two equivalent sp hybrid orbitals that are oriented in a linear geometry.

The set of sp orbitals appears similar in shape to the original p orbital, but there is an important difference. The number of atomic orbitals combined always equals the number of hybrid orbitals formed.

The p orbital is one orbital that can hold up to two electrons. The sp set is two equivalent orbitals that point 120° from each other. The two electrons that were originally in the s orbital are now distributed to the two sp orbitals, which are half filled.

Therefore, due to the sp hybrid and 120-degree angle option B is correct

#SPJ2

Describe the critical property ofelectrons in 2s versus 2p orbitals that causes the radial distribution functions of these orbitals to have different shapes about the nucleus such that 2s electrons effectively penetrate closer to the nucleus than do electrons in 2p orbitals.Then, write an expression for the potential energy function describing this effect.

Answers

Answer:

Answer is explained in the explanation section below.

Explanation:

Penetration refers to the proximity of electrons in an orbital to the nucleus.

Deeper-penetrating electrons have less shielding and therefore a higher Effective nuclear charge (Zeff), but they better shield other electrons.

To illustrate penetration, we may use the idea of Zeff, or effective nuclear charge. It's actually the difference between the number of charged protons and the number of shielded electrons. To put it another way, how effective the nucleus is at attracting electrons. Since they do not shield themselves, the core electrons penetrate the most and are exposed to the most strong nuclear charge.

The electron probability density is highest in the orbital's centre or nucleus for 28-orbitals.

In a multi-electron unit, the electron density near the nucleus of an atom for each shell and subshell of an electron is used to measure the nucleus penetration by an electron.

Since it has a higher electron density near the nucleus, the 2s electron penetrates the nucleus of the atom more than the 2p electron.

A 2s electron is less well shielded by the core electrons than a 2p electron because it can spend more time near the nucleus as a result of the penetration.

when 4.73g of solid was heated, the residue weighed 4.10g 320 cubic centimetre of gas( at RTP) was evolved. calculate the molecular mass of the gas​

Answers

Answer:

48 g/mol

Explanation:

Step 1: Calculate the mass of the gas (m)

According to the law of conservation of mass, the mass of the solid before the decomposition must be equal to the sum of the masses of the solid residue and the gas

mSolid = mResidue + mGas

mGas = mSolid - mResidue = 4.73 g - 4.10 g = 0.63 g

Step 2: Convert 320 cm³ to L

We will use the conversion factor 1 L = 1000 cm³.

320 cm³ × 1 L/1000 cm³ = 0.320 L

Step 3: Calculate the moles of gas (n)

The gas is at room temperature (298.15 K) and room pressure (1 atm). We can calculate the moles of gas using the ideal gas equation.

P × V = n × R × T

n = P × V/R × T

n = 1 atm × 0.320 L/(0.0821 atm.L/mol.K) × 298.15 K = 0.0131 mol

Step 4: Calculate the molecular mass of the gas (M)

We will use the following expression.

M = m/n = 0.63 g/0.0131 mol = 48 g/mol

See explanation

Explanation:

CO2 is often released by the combustion of fossil fuels. Fossil fuels are quite common sources of energy in our world today.

A lot power plants, vehicles, etc rely on energy produced as a result of the combustion of fossil fuels yielding carbon dioxide.

Hence, irrespective of the fact that CO2 leads to global warming but Nigeria is still ranked one of the greatest emitters of CO2.

The menace of rising CO2 leves can only be checked by stakeholders in the energy sector coming together to exploit renewable energy as a regular source of energy.

Decreasing the volume of a gas would _______________. A. Decrease the temperature. B. Increase the amount liters. C. Decrease the moles. D. Increase the pressure.

Answers

Answer:

D. Increase the pressure.

Explanation:

Okay, lets break this down.

So first, lets imagine what decreasing the volume looks like. I like to think of it as squishing a balloon or water bottle. You condense what's inside it. So, with this in mind, lets look at the question.

A. Decrease temperature:

Does this happen when you squeeze something? It gets colder? No, that's not true. So we can eliminate that one.

B. Increase the liters:

Does this happen when you squeeze something? It gets larger? It takes up more space? No, that's not true. So we can eliminate that one.

C. Decrease in moles:

Okay, so moles is just a fancy way of saying "stuff." So does the amount of "stuff" decrease when you squeeze something? No, it just gets closer together. It's denser. So we can eliminate that one.

D. Increase the pressure:

Now we're getting somewhere!! When you squeeze a balloon, the pressure DOES increase because you are condensing the gas inside it. That's why balloons will pop if you squeeze too hard, the pressure is too great and has to escape. So yes, this is your answer.

Answer: D. Increase the pressure

11) A fixed amount of gas at 25.0 °C occupies a volume of 8.66 L when the pressure is 629 torr. Use
Charles's law to calculate the volume (L) the gas will occupy when the temperature is increased to
112 °C while maintaining the pressure at 629 torr.
A) 1.93
B) 38.8
C) 11.2
D) 9.26
E) 6.70

Answers

Answer:

Option C. 11.2 L

Explanation:

From the question given above, the following data were obtained:

Initial temperature (T₁) = 25.0 °C

Initial volume (V₁) = 8.66 L

Final temperature (T₂) = 112 °C

Pressure = constant

Final volume (V₂) =?

Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T₁) = 25 °C

Initial temperature (T₁) = 25 °C +273

Initial temperature (T₁) = 298 K

Final temperature (T₂) = 112 °C

Final temperature (T₂) = 112 °C + 273

Final temperature (T₂) = 385 K

Finally, we shall determine final volume of the gas. This can be obtained as follow:

Initial temperature (T₁) = 298 K

Initial volume (V₁) = 8.66 L

Final temperature (T₂) = 385 K

Pressure = constant

Final volume (V₂) =?

V₁/T₁ = V₂/T₂

8.66/298 = V₂/385

Cross multiply

298 × V₂ = 8.66 × 385

298 × V₂ = 3334.1

Divide both side by 298

V₂ = 3334.1 / 298

V₂ = 11.2 L

Thus, the final (i.e new) volume of the gas is 11.2 L
