Explanation:

Due to their stronger metallic bonding and more compact atomic structure, the transition elements have higher melting and boiling temperatures and are often denser than the alkali metals.

Elements from Group 1 have similar properties. All of them are supple silver metals. These metals are extremely reactive and have low melting temperatures due to their low ionisation energy. As you descend the chart, this family becomes more reactive.

The d orbitals of transitional elements are only partially filled. A transition element is defined by IUPAC as an element that may form stable cations and has an electron d subshell that is only partly filled.

A liquid is allowed to evaporate and leaves no residue. It can not be determined whether it was an element, a compound, or a mixture.

A water vapor molecule stays roughly 10 days in the atmosphere after it has evaporated. Water vapor starts to cool back down as it ascends higher in the atmosphere. The water vapor condenses when it becomes cold enough, turning it back into liquid water. Eventually, individual water droplets will condense to create clouds and precipitation.

It is not possible to determined whether it would be an element, a compound and mixture because the size of the particle will be too less.

A method for separating homogenous mixtures with one or even more dissolved salts is called evaporation. The procedure separates the liquid from the solid components. Usually, the procedure entails heating the combination until there is no more liquid is present.

Therefore, it can not be possible to determined whether it was an element, a compound, or a mixture by evaporation.

The chemical condition that describes the electrons in a water molecule being shared unequally between the hydrogen and oxygen atoms is called polar covalent bonding.

In polar covalent bonds, the electrons are unequally shared due to the electronegativity difference between the atoms involved. In the case of a water molecule, oxygen is more electronegative than hydrogen, causing the oxygen atom to attract the shared electrons more strongly.

As a result, the oxygen atom becomes slightly negatively charged while the hydrogen atoms become slightly positively charged. This polarity gives water its unique properties, such as its ability to form hydrogen bonds and its high surface tension.

In summary, that this describes the unequal sharing of electrons in a water molecule due to the electronegativity difference between hydrogen and oxygen atoms.

Approx mass(amu) of Particles proton, neutron and  electron is 1, 1, 0.

Electrons are found outside the nucleus in electron shells, not inside the nucleus. Therefore, the location of electrons should be listed as "Extracellular space (outside nucleus)." The approximate mass of an electron is about 1/1836 amu, which is negligible compared to the mass of a proton or neutron. Therefore, the mass of an electron is usually listed as "negligible" or "approximately 0."

Protons are positively charged subatomic particles found in an atom's nucleus. A proton has a charge of +1 and an approximate mass of 1 atomic mass unit (amu). The atomic number of an element is determined by the number of protons in its nucleus.

Neutrons are neutral subatomic particles found in an atom's nucleus. A neutron's charge is zero, which means it has no charge. A neutron has an approximate mass of 1 amu, which is similar to the mass of a proton. The number of neutrons in an atom's nucleus can vary, resulting in isotopes of the same element.

The fermentation reaction of glucose produces C\(_2\)H\(_5\)OH and CO\(_2\) according to the following equation:

C\(_6\)H\(_{12}\)O\(_6\) → 2C\(_2\)H\(_5\)OH + 2CO\(_2\)

The molar mass of glucose (C\(_6\)H\(_{12}\)O\(_6\)) is 180.16 g/mol, so 1.00 mole of glucose corresponds to 180.16 g.

To find the theoretical yield of C\(_2\)H\(_5\)OH, we need to use stoichiometry. From the balanced equation, we see that 1 mole of glucose produces 2 moles of C\(_2\)H\(_5\)OH. Therefore, 1.00 mole of glucose should produce 2.00 moles of C\(_2\)H\(_5\)OH.

The molar mass of C\(_2\)H\(_5\)OH is 46.07 g/mol, so 2.00 moles of C\(_2\)H\(_5\)OH corresponds to 92.14 g.

The actual yield of C\(_2\)H\(_5\)OH obtained is 32.3 g.

The percent yield is calculated as (actual yield/theoretical yield) x 100%. Therefore, the percent yield of C\(_2\)H\(_5\)OH is:

(32.3 g/92.14 g) x 100% = 35.1%

Remaining amount ≈ 48.38 mg

Approximately 48.38 mg of iodine-123 will remain at 10 am the following day.

To determine the amount of iodine-123 remaining at 10 am the following day, we need to calculate the number of half-lives that have passed from 8 am on Monday to 10 am the next day.

Since the half-life of iodine-123 is 13 hours, there are (10 am - 8 am) / 13 hours = 2 / 13 = 0.1538 of a half-life between those times.

Each half-life reduces the amount of iodine-123 by half. Therefore, the remaining amount can be calculated as:

Remaining amount = Initial amount * (1/2)^(number of half-lives)

Initial amount = 50.0 mg

Number of half-lives = 0.1538

Remaining amount = 50.0 mg * (1/2)^(0.1538)

Remaining amount ≈ 50.0 mg * 0.9676

Remaining amount ≈ 48.38 mg

Approximately 48.38 mg of iodine-123 will remain at 10 am the following day.

The types of emissions that mostly occur when an isotope undergoes radioactive decay include alpha particles, beta particles, and gamma rays.

The types of emissions that can occur when an isotope undergoes radioactive decay are alpha, beta, and gamma radiation. Alpha particles are made up of two protons and two neutrons and are positively charged. Beta particles are either electrons or positrons, and they are negatively or positively charged, respectively. Gamma radiation is a high-energy electromagnetic radiation that has no charge.

During alpha decay, the nucleus of an atom emits an alpha particle. This changes the atomic number of the element, but not its mass number. Beta decay occurs when a neutron in the nucleus of an atom transforms into a proton and an electron or positron is emitted. This can change the atomic number of the element, but not its mass number. Gamma decay occurs when the nucleus of an atom releases energy in the form of gamma radiation. This does not change the atomic number or mass number of the element.

The gas is compressed, the pressure of the gas increases. In this case, the cylinder compresses 50ml of air down to 10ml without any change in temperature. This means that the volume of the gas has decreased, which would cause an increase in pressure.

The calculate the pressure of the air at the smaller volume, we can use the formula P1 x V1 = P2 x V2 Where P1 is the initial pressure, V1 is the initial volume, P2 is the final pressure, and V2 is the final volume. We know that the initial volume is 50ml and the final volume is 10ml. We also know that there is no change in temperature, so the initial pressure and final pressure are equal. Therefore, we can rewrite the formula as P1 x 50ml = P1 x 10ml Solving for P1, we get P1 = (10ml/50ml) x P1 = 0.2 x P1 This means that the pressure of the air at the smaller volume is 0.2 times the initial pressure. If we assume that the initial pressure was atmospheric pressure (around 101 kPa), then the final pressure would be P2 = 0.2 x 101 kPa P2 = 20.2 kPa Therefore, the pressure of the air at the smaller volume is approximately 20.2 kPa.

where Nf is the final number of nuclei, Ni is the initial number of nuclei, and n is the number of half-lives.

Given information,

Ni = 6.02 x 10²³ nuclei

Nf = 0.376 x 10²³ nuclei

Thus,

0.376 x 10²³ = (6.02 x 10²³) × (1/2)^(n)

Dividing both sides of the equation by (6.02 x 10²³):

0.376 / 6.02 = (1/2)^(n)

0.0625 = (1/2)^(n)

Take the logarithm of both sides using a base of 1/2:

log base (1/2) of 0.0625 = n

log base 2 of 0.0625 / log base 2 of (1/2) = n

(-4) / (-1) = n
