The trend that we see in the ionization energy across the period is an Ionization energy increases as we move across the period from left to right. Order of ionization energy across period 2

Li < B < Be < C < O < N < F < Ne

What is Ionization energy?

Ionization energy represents the energy required to remove an electron from an isolated gaseous atom (X) in its ground state.

It is minimum at the alkali metals and their low ionization enthalpies can be correlated with their high reactivity

The Ionization energy is maximum at the nobel gases since they have closed electron shells.

As you move across a period (left to right) in the periodic table, the ionization energy of the elements generally increases. This means that it takes more energy to remove an electron from an atom as you move from left to right in a period. This trend can be explained by the fact that the atomic radius decreases and the electron shielding remains constant as you move from left to right in a period, which results in a stronger attraction between the nucleus and the electrons and therefore requires more energy to remove an electron.

Trends for Ionization energy

There are two trends, the first ionization enthalpy generally increases as we go across a period from left to right and decreases as we go down in a group.

Two factors to understand these trends are

Li < B < Be < C < O < N < F < Ne

The hypothesis for Susie's experiment could be that the freezing points of the water, salt, and sugar solution mixtures will be different from each other due to the presence of salt and sugar.

This hypothesis is supported by the observation that solutes, like salt and sugar, can lower a solvent's freezing point, like water.

The experiment will test how these solutes affect water's freezing point and will determine which mixture has the lowest freezing point. The results of the experiment could provide insight into the relationship between solutes and the freezing point of solutions.

The atomic mass of sodium is 22.99 g/mol, while the atomic mass of calcium is 40.08 g/mol. To determine the mass of an equivalent number of calcium atoms as sodium atoms, we would multiply the mass of the sodium sample by the ratio of the atomic masses of calcium to sodium:

Mass of calcium = Mass of sodium * (Atomic mass of calcium / Atomic mass of sodium)

Mass of calcium = 60.0 g * (40.08 g/mol / 22.99 g/mol)

Mass of calcium = 104.01 g

So the mass of an equivalent number of calcium atoms as sodium atoms present in the given sample would be approximately 104.01 g.

The atomic number is 14 protons.

What is an atomic number?

An atomic number is a number that represents the number of protons in the nucleus of an atom. It is also referred to as the proton number. The atomic number of an element is always the same, regardless of the mass of the atom. The mass number (symbolized as A) is the sum of the number of protons and the number of neutrons in the nucleus of an atom and also unique to each element. For example, the element Carbon has an atomic number of 6 and a mass number of 12. This means that Carbon atoms have 6 protons and 6 neutrons in their nucleus.

Since protons + neutrons = mass number

Mass  - neutrons = protons.

So, plugging into the formula:

30−16= 14 protons.

Because oxygen gas has a molar mass of 32 g/mol, the mass of oxygen generated is 0.0753 g. The sample contains 91.36% sodium chlorate by mass.

A chemical reaction is a process that converts one or more compounds, known as reactants, to one or more distinct substances, known as products. Chemical elements or compounds are examples of substances.

Here,

a. To calculate the mass of oxygen formed in the reaction, the volume of oxygen gas collected must be converted to its equivalent moles. The molar volume of an ideal gas at 22 degrees Celsius and a pressure of 734 torr is 24.45 L/mol. Therefore, the number of moles of oxygen gas produced is:

n = (57.2 mL) / (24.45 L/mol) = 2.349 x 10^-4 mol

The molar mass of oxygen gas is 32 g/mol, so the mass of oxygen produced is:

m = n * M = 2.349 x 10^-4 mol * 32 g/mol = 0.0753 g

b. To calculate the mass percent of sodium chlorate in the sample, divide the mass of sodium chlorate by the total mass of the sample and multiply by 100%. The mass of sodium chlorate in the sample is:

m_NaClO3 = 0.8765 g - 0.0753 g = 0.8012 g

So, the mass percent of sodium chlorate in the sample is:

mass percent = (m_NaClO3 / 0.8765 g) * 100% = 91.36%

The molar mass of oxygen gas is 32 g/mol, so the mass of oxygen produced is 0.0753 g. The mass percent of sodium chlorate in the sample is 91.36%.

Answer: you call them isotopes

Explanation:

Amino acids have similar structures, the functional group linked to the central carbon atom makes one amino acid different from another (also known as the alpha carbon).

Each amino acid has a different functional group, also known as the R group, which gives it its own special characteristics. The R group, which might be a hydrogen atom, an alkyl group, a functional group with a charge, or a functional group with a polar or hydrophobic property, governs the physical and chemical properties of an amino acid.

The distinctive R group connected to the alpha carbon, together with the carbon, hydrogen, nitrogen, oxygen, and sulfur atoms that make up the backbone structure, are all included in the chemical formula of an amino acid.

In this case, if we had more Cl2, then Al would be the limiting reactant, and if we had more Al, then Cl2 would be the limiting reactant.

The limiting reactant in a reaction is the reactant that is completely consumed before any of the other reactants run out, thereby limiting the amount of product that can be formed.

The excess reactant is the reactant that remains after the reaction has been completed, and is present in an amount greater than the stoichiometric ratio of the reaction.

In the reaction 2 Al + 3 Cl2 → 2 AlCl3, we can use the mole ratio of aluminum to chlorine to determine the limiting and excess reactant. If we assume that we have equal amounts of Al and Cl2, then we have 2 moles of Al and 3 moles of Cl2.

According to the reaction equation, for every 2 moles of Al, 3 moles of Cl2 are required. Since we only have 3 moles of Cl2, this means that Cl2 is the limiting reactant, as it will run out before Al. The amount of AlCl3 that can be produced is limited by the amount of Cl2, and so Al will become the excess reactant.

Therefore, if we had more Cl2, then Al would be the limiting reactant, and if we had more Al, then Cl2 would be the limiting reactant. The limiting reactant depends on the relative amounts of the reactants present in the reaction mixture.
