When molecules present in a bowl of hot soup then they do vibration due to high kinetic energy.

What are molecules?

Molecules are the example of chain substance, which can be prepared by the addition of two or more than 2 atoms of same or different nature.

In a hot soup bowl, kinetic energy of the molecules present in that soup increases due to which they move with higher velocity and also shows vibration in their mean position.

Hence, option (C) is correct i.e. vibrate.

Write the full electron configuration for a Ca+ ion.

Answers

Answer:

[Ar] 4s²

Explanation:

The full electron configuration for the Ca+ ion is:

1s² 2s² 2p⁶ 3s² 3p⁶.

How to determine the electron configuration for the Ca+ ion

To determine the full electron configuration for a Ca+ ion, we need to remove one electron from the neutral calcium atom (Ca). The neutral calcium atom has the electron configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s².

When Ca loses one electron to form the Ca+ ion, the electron removed comes from the highest energy level, which is the 4s orbital.

Therefore, the full electron configuration for the Ca+ ion is:

1s² 2s² 2p⁶ 3s² 3p⁶.

Silicon dioxide is a solid at room temperature and methanol is a liquid. What substance has the higher melting point?

Answers

Answer:

methanol because it is liquid at room temperature which means that it melts at a lower temperature

Silicon dioxide is a solid at room temperature and methanol is a liquid. Silicon dioxide has a higher melting point than methanol because silicon dioxide is solid, and with increasing temperature, it will melt.

What is a melting point?

Melting point is that point or temperature at which the solid items are converted into liquid, and it changes their atoms and the atoms lose their compactness.

Here, two compounds are given, Silicon dioxide and methanol, the first one is solid at room temperature, so it will need more temperature to melt down and methanol is still liquid at room temperature, so its melting point is low.

Thus, methanol is a liquid while silicon dioxide is a solid at ambient temperature. Because silicon dioxide is a solid and melts at greater temperatures, it has a higher melting point than methanol.

How many Mg atoms are there in 0.764 moles of Mg?
atoms

Answers

Answer:

1.135986935e+39

Answer:

[tex]\boxed {\boxed {\sf 4.60 \times 10^{23} \ atoms \ Mg}}[/tex]

Explanation:

We are asked to find how many atoms of magnesium are in 0.764 moles of magnesium.

We convert moles to atoms using Avogadro's Number or 6.022 × 10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this case, the particles are atoms of magnesium. So, there are 6.022 × 10²³ atoms of magnesium in 1 mole of magnesium.

Convert using dimensional analysis and set up a conversion factor using Avogadro's Number.

[tex]\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 \ mol \ Mg}[/tex]

We are converting 0.764 moles of magnesium to atoms, so we multiply by this value.

[tex]0.764 \ mol \ Mg *\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 \ mol \ Mg}[/tex]

The units of moles of magnesium cancel.

[tex]0.764 *\frac{6.022 \times 10^{23} \ atoms \ Mg}{1 }[/tex]

[tex]0.764 *6.022 \times 10^{23} \ atoms \ Mg[/tex]

[tex]4.600808 \times 10^{23} \ atoms \ Mg[/tex]

The original value of moles (0.764) has 3 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place. The 0 in the thousandth place tells us to leave the 0 in the hundredth place.

[tex]4.60 \times 10^{23} \ atoms \ Mg[/tex]

0.764 moles of magnesium contains approximately 4.60 × 10²³ atoms of magnesium.

adjoa's gross salary for last month was ghs 4687.24. if ghs 421.78 was deducted from adjoa's salary pay,how much take home pay did adjoa earned this past month?​

Answers

Since Ghs. 421.78 was deducted from Adjoa's salary pay, her take home pay is Ghs. 4265.46.

Given the following data:

Adjoa's gross salary = Ghs. 4687.24.Deduction = Ghs. 421.78

Gross profit can be defined as the profit earned by a business after subtracting its cost of manufacturing and distributing goods from its total revenue (sales).

On a related note, gross salary is the amount of money earned by an individual before any deduction such as tax.

To find how much take home pay Adjoa earned this past month:

If you take 35 mL of solution from (#2c) and add 0.225 L of water what is the concentration of the resulting solution in (% v/v)? (hint: you must determine the final volume first)
HELP

Answers

We want to find the concentration of the resulting solution of mixing 35mL of a given solution and 0.225 L of water.

We will find that the concentration is 13.5%.

First, we need to write both of these in the same units.

We know that:

1000 mL = 1L

Then:

35 mL = 0.035 L

So when we mix the solution and the water we end with a total volume of:

V = 0.035L + 0.225L = 0.260L

The concentration of solution will be equal to the quotient between the volume of solution we used (0.035 L) and the total volume of the mixture (0.260L)

We will get:

Concentration = (0.035L)/(0.260L) = 0.135

Now to write it as a percentage, we only need to multiply this by 100%.

0.135*100% = 13.5%

This means that the mixture has a concentration of the 13.5%.

How many protons, neutrons, and electrons are there in a neutral atom of 60 Co (cobalt- 60 )?

Answers

Cobalt is comprised of 27 protons, 33 neutrons, and 27 electrons

Cobalt-60 is comprised of 27 protons, 33 neutrons, and 27 electrons. Nuclear reactors are used to artificially create it.

What is cobalt- 60?

A radioactive isotope containing cobalt with something like a half-life of 5.2713 centuries is called cobalt-60 (60Co). Nuclear reactors are used to artificially create it. Neutron irradiation of bulk material of the monoisotopic as well as mononuclidic cobalt element 59 Co is necessary for deliberate industrial manufacture.

The accidentally generated 60 Co in the latter instance (inside the absence of additional cobalt) is mostly the product of many phases involving neutron activation on iron isotopes inside the reactor. Cobalt-60 is comprised of 27 protons, 33 neutrons, and 27 electrons.
