Carbon dioxide, when present in sufficient amounts, will bind with water to form ____________ , which is capable of dissociating into bicarbonate and hydrogen ions.

This is a redox reaction but not a combustion reaction.

A type of chemical reaction that involves a transfer of electrons or gain of electrons between two-element. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes.

∴ The reaction is Redox ✓ not combustion

By applying Charles law, the final volume of the gas is equal to 42 mL.

Given the following data:

To find the final volume of the gas, we would apply Charles law:

Charles law states that when the pressure of an ideal gas is kept constant, the volume of the gas is indirectly proportional to the absolute temperature of the gas.

Mathematically, Charles law is given by the formula;

[tex]\frac{V}{T} =k\\\\\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

Where;

Substituting the given parameters into the formula, we have;

[tex]\frac{140}{400} = \frac{V_2}{120} \\\\140 \times 120 = 400V_2\\\\16800 = 400V_2\\\\V_2 = \frac{16800}{400}[/tex]

Final volume = 42 mL.

Answer:

BeF2

Explanation:

The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.

The valence electron of an atom determines how an atom goes into bonding.

Beryllium(Be) has 4 electron and has 2 valence electron. To fulfil the octet rule, it can easily give out this 2 electron during bonding.

Fluorine(F) has 9 electrons and 7 valency electrons. To fulfil the octet rule, it readily accepts a single electron.

The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.

This means 1 atom of beryllium combines with 2 atoms of fluorine to form beryllium fluoride. The beryllium give its 2 valency electrons to the 2 atoms of fluorine. The 2 atoms of fluorine will now have a valency electron of 8 each. The octet rule has been fulfilled at this point.

Anions are the name for ions that have a negative charge. The body contains several common chemicals as ions. Sodium, potassium, calcium, chloride, and bicarbonate are typical examples.

Negatively charged electrons are called anion. When non-metals gain electrons, they are produced. They absorb one or more electrons. They have a negative charge overall as a result. The ion concentration iodide ( I- ), chloride ( Cl- ), and hydroxide are among examples ( OH– ).

The electrode where reduction takes place in any electrochemical cell  is characterized as the cathode. On the other extreme, the positive electrode will draw anions, or negative ions, to itself.

Thus, when an atom obtains electrons, it transforms into the negatively-charged ion known as an anion.

The periodic table, also known as the periodic table of chemical elements, is a tabular display of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry.

Explanation:

The periodic table is a tabular arrangement of chemical elements that classifies elements according to repeating qualities and is structured by increasing atomic number. Metals are located on the left side of the table, whereas nonmetals are located on the right. The columns are referred to as groupings.
