The element selected is carbon and the isotopes are carbon-12, carbon-13, and carbon-14.

The number of protons, electrons, and neutrons for each isotope of carbon are as follows:

The isotope notation for each is¹²₆C, ¹³₆C, and ¹⁴₆C.

The carbon-14 isotope is used in the radioactive dating of substances.

Isotopes are atoms of the same element that differ from each other in their masses.

Isotopes of the same element have different masses as a result of the difference in the number of neutrons in the nucleus of the atoms of the element.

The existence of isotopes of elements accounts for why the atomic masses of elements are not whole numbers.

Answer:

Surface tension due to cohesion

Explanation:

Water molecules are polar meaning they have dipoles. The hydrogen end is partially positive while the oxygen end is partially negative. This is because oxygen with high atomic mass attracting most of the molecule's electron cloud to its end.

Due to this phenomenon water molecules act like little magnets that attract each other. The attraction of the molecules forms hydrogen bonds with each other. This is called cohesion (attraction of similar molecules).  Due to this, water is able to create a surface tension that acts like a ‘skin’ and can support some weight (including its own weight) without collapsing.

Explanation:

The mass of the zinc II hydroxide produced is 22.77 g.

It is common that we use the stoichiometry of a reaction to be able to obtain the parameters that have to do with the reaction. In his case, we already have the balanced reaction equation of this reaction and this is our basic stock in trade for the task that is ahead of us.

Now we have; 2 NaOH(aq) + Zn(NO₃)₂(aq) → Zn(OH)₂ (s) + 2 NaNO₃ (aq)

Number of moles of the sodium hydroxide =  18.5 g/40 g/mol = 0.46 moles

Number of moles of the zinc II nitrate solution = 1.00 M * 0.800 L = 0.8 moles

If 2 moles of the sodium hydroxide reacts with 1 mole of the zinc II nitrate

0.46 moles  of the sodium hydroxide reacts with; 0.46 moles * 1 mole/ 2 moles

= 0.23 moles

Hence the sodium hydroxide is the limiting reactant.

Thus;

2 mole of sodium hydroxide produces 1 mole of zinc II hydroxide

0.46 moles of sodium hydroxide produces 0.46 moles  * 1 mole/2 moles

= 0.23 moles

Mass of the  zinc II hydroxide =  0.23 moles * 99 g/mol

= 22.77 g

Explanation:

The ratio of the carbon to other atoms would be 2.49375:3.9901:1.000 and the empirical formula of the compound would be  [tex]C_2H_8O[/tex]

The compound contains C, H, and O according to the following information:

C = 4.9875 mol

H = 7.9802 mol

O = 2.00 mol

In order to obtain the empirical formula of the compound, divide the mol of each atom by the smallest mol. In this case, the smallest mol is 2.00

C = 4.9875/2.00

  = 2.49375

H = 7.9802/2.00

    = 3.9901

O = 2.00/2.00

   = 1.0000

Thus, the ratio of carbon to the rest of the atoms present in the compound is 2.49375:3.9901:1.000

In order to find the empirical formula of the compound, the mole of each atom needs to be approximated to the nearest whole number.

C = 2

H = 8

O = 1

Thus, the empirical formula of the compound is [tex]C_2H_8O[/tex].

83.246 ounces of silver is required to make the silver figure.

It is given that 10.49 g/cm^3 is the density of silver at Room temperature and the volume of Silver is 225cm^3.

To prepare silver of 225cm^3 of volume, we require the following:

Density = Mass/Volume

Mass = Density x Volume

Amount of silver = 10.49x225

Amount of silver = 2360.25 g

We know that,

100g = 3.5274 ounces

Then,

= 3.5274/100

= 0.035274 ounces of silver.

The mass of silver required in ounces = 2360.25 x 0.035274

The mass of silver in ounces = 83.246 ounces.

Radiation is produced when unstable or radioactive atoms through the process of becoming stable. We refer to this process as radioactive decay over time. Two protons and two neutrons are lost from the nucleus as a result of alpha decay.

An unstable nucleus releases radiation and changes into the nucleus of one or more additional elements during a nuclear decay process, also known as radioactive decay.

The ensuing offspring nuclei are less energetic and heavier than the parent nucleus that underwent decay, making them more stable.

For example, by producing an alpha particle, the unstable uranium-238 nucleus naturally decays into a thorium-234 nucleus. The most prevalent radioactive decay processes are decay, emission, decay, positron emission, and electron capture.

The amount of coconut milk added if the final temperature of the soup was found to be 72.0 °C is 430g

The amount of coconut milk added can be found using the equation:

m₁C₁ΔT₁ = m₂C₂ΔT₂

Where m is the mass, C is the specific heat, and ΔT is the change in temperature.

In this equation, m₁ is the mass of the coconut milk, C₁ is the specific heat of the coconut milk, ΔT₁ is the change in temperature of the coconut milk, m₂ is the mass of the soup, C₂ is the specific heat of the soup, and ΔT₂ is the change in temperature of the soup.

We are given the specific heat of the coconut milk and the soup, the change in temperature of the soup, and the final temperature of the soup. This allows us to solve for the mass of the coconut milk, which is m₁.

m₁ = m₂C₂ΔT₁/C₁ΔT₂

m₁ = (1175 g)(3.60 J/g°C)(72.0°C - 90.0°C)/(3.98 J/g°C)(72.0°C - 25.0°C)

m₁ = -427 g

This answer is impossible because the mass of a substance cannot be negative. By solving it in other means we get,

The amount of coconut milk added can be found using the equation

ΔQ = mCΔT

ΔQ is the heat transfer, m is the mass, C is the specific heat, and ΔT is the change in temperature.

We are given the specific heat of coconut milk (Cs = 3.98 J/g°C), the initial temperature of the coconut milk (25.0°C), the final temperature of the soup (72.0°C), and the heat transfer of the soup (ΔQ = 1176 * 3.6*47 = 81168 Joules).

Therefore, the equation becomes:

81168 = m(3.98)(47)

m = 81168 / (3.98 * 47)

m = 81168 / 189.06
