Part A; A stronger solution of sodium bicarbonate require more hydrochloric acid will be required

Part A; The reason why more HCl is required is due to the presence of more hydroxyl ions in the solution

The reason arriving at the above responses are as follows;

Part A

Sodium bicarbonate, NaHCO₃, is baking soda = A basic salt; has the capacity to deprotonate water

Hydrochloric acid, HCl = An acid

The reaction between sodium bicarbonate and hydrochloric acid is presented as follows;

NaHCO₃ + HCl → CO₂ + H₂O + NaCl

The equation for the ionic reaction is as follows;

Na⁺(aq) + HCO₃⁻(aq)  + H⁺(aq) + Cl⁻(aq)  → Na⁺(aq) + Cl⁻(aq) + H₂O(l) + CO₂(g)

In water, we have;

HCO₃⁻(aq) + H₂O(l) ⇄ H₂CO₃(aq) + OH⁻(aq)

The presence of a stronger solution of sodium bicarbonate, will produce more hydroxyl ions, OH⁻(aq), which will require, more HCl to neutralize

Therefore, if a stronger solution of sodium bicarbonate was used, more hydrochloric acid will be required

Part B

The solution of stronger sodium bicarbonate will contain a higher concentration of hydroxyl ions and therefore, require more HCl, to neutralize

Answer:  MgCl2

Explanation:

Convert the masses of Mg and Cl to moles:

Mg:  1.2g/24g/mole = 0.050 moles

Cl:    3.55g/35.5g/mole = 0.100 moles

The ratio of Cl to Mg is 2 to 1:  (0.100 moles Cl/0.050 moles Mg),  Therefore there must be 2 Cl for every Mg:

MgCl2

This is the empirical formula since all we know is the ratio.  If could also be Mg2Cl4, Mg3Cl6, etc,  [i.e., (MgCl2)n]

Explanation:

1. an element with a high electronegativity and an element with a single valence electron YES

2. an element with a high electronegativity and an element with a single valence electron Duplicate

3. an element with a high electronegativity and an element with a full shell of electrons NO

4. an element with a high electronegativity and an element with a full shell of electrons Duplicate

5. an element with a high electronegativity and an element with low reactivity NO

6. an element with a high electronegativity and an element with low reactivity Duplicate

7. an element with a high electronegativity and a second element with a high electronegativity NO

Elements have electronegativities because of the tendency of attracting electrons. An element with a single valence electron and high electronegativity will react with each other. Thus, option A is correct.

Electronegativity has been defined by the atom's tendency to attract the electrons that are in sharing for the formation of the chemical bond. The atomic number and the atomic radii affect electronegativity.

High electronegative elements are electron acceptors and are characterized by an almost full valence shell. The electron is required by them to achieve stability and complete octet. Elements with full shells cannot accept more electrons.

Therefore, option A. high electronegative element reacts easily with a valence electron to form a bond.

Answer:

D. the electron has a neg. charge and is found outside of the nucleus.

Explanation:

the proton has a positive charge, while the neutron has no charge at all. both are found in the nucleus.

the electron has a negative charge, but stays outside of the nucleus in the electron cloud, constantly moving around.

Taking into account the constitution of an atom, the correct statement is "The electron has a negative charge and iş found outside of the nucleus."

An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.

Every atom consists of:

In other words, the atomic nucleus is the central part of the atom that is made up of protons and neutrons, while the orbitals or peripheral region is an area where electrons are found.

The neutron is an electrically neutral subatomic particle, while the proton has a positive electrical charge. Electrons have a negative charge, move around the nucleus at different energy levels and are attracted to protons, positive in the atom through electromagnetic force.

In summary, the correct statement is "The electron has a negative charge and iş found outside of the nucleus."

Answer: In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

These are the answers for the Atomic Number Quick Check

Explanation:

1. An element is highly conductive, highly reactive, soft, and lustrous. The element most likely belongs to which group?: alkali metals

2. How does mercury differ from other metals?: It is not solid under normal conditions.

3. Based on patterns in the periodic table, which element is the least malleable in its solid state?: phosphorus (P)

4. In which group of elements does tellurium (Te) belong?: metalloids

5. Which statement describes the properties of lanthanoids and actinoids?: They are malleable and lustrous, and they tend to conduct both electricity and thermal energy.

Hope this helps :)

Based on patterns of the periodic table, the chemical element which is the least malleable in its solid state is: D. Phosphorus (P).

A periodic table refers to an organized tabular arrangement of all the chemical elements, typically arranged in order of increasing atomic number or number of protons (in rows).

Phosphorus is denoted by the chemical symbol P and it is a chemical element with an atomic number of fifteen (15) and as such it is found in group five (5) of the periodic table.

Malleability is one of the chemical properties of a chemical element and it is simply a measure of it softness such as when hammered.

According to trends (patterns) of the periodic table, Phosphorus (P) is the chemical element which is the least malleable in its solid state.

Salt lowers the freezing point of water by interfering with the intermolecular forces of the water molecules, allowing for less interactions between water molecules.

The Freezing point is the temperature of a liquid at which it changes its state from liquid to solid at atmospheric pressure.

Salt molecules block water molecules from packing together when temperature is lowered. It then prevents them from becoming ice. More water molecules leave the solid phase than the ones entering the solid phase. Freezing point depression occurs when the freezing point of the liquid is lowered by addition of solute.

Hence, option B is correct.

I think an atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.
