Taking into account the constitution of an atom, an atom is neutral because it has the same number of protons as it has electrons.

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

Every atom consists of a nucleus in which neutrons and protons meet and energy levels where electrons are located.

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.

An atom is considered electrically neutral when it has the same number of positive and negative charges. That is, an electrically neutral atom has the same number of protons (with a positive charge) and electrons (with a negative charge).

In summary, an atom is neutral because it has the same number of protons as it has electrons.

Answer:

c) removing fluoride ions.

Explanation:

Hello!

In this case, for this solubility product problem, it is very convenient to write the undergoing ionization reaction:

[tex]CaF_2(s)\rightleftharpoons Ca^{2+}(aq)+2F^-(aq)[/tex]

In such a way, via the Le Chatelier's principle, we remember that the addition of reactants shifts the reaction towards products, adding products shifts the reaction towards reactants, removing reactants shifts the reaction towards reactants and removing products shifts the reaction towards products. In means, that the best way to shift this reaction away from solid calcium fluoride and toward the dissolved ions is c) removing fluoride ions, because it is a product and its removal favors the formation of more products.

Best regards!

The decay reaction of Carbon-14 which releases Beta particles, resulting in the element Nitrogen-14

Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,  

Carbon-14 emits beta β ₋₁e⁰ particles , so the atomic number increases by 1, the mass number remains the same

Reaction

Answer:

Now, what happens if we turn the room thermostat up to 80 degrees F? Looking at your Capacity of Saturated Air table, you can see that as air temperatures rise, there is an increase in the ability of the air to hold moisture. At 80 degrees F the capacity of air increases to where it can hold 21.537 g/kg of water vapor.

Explanation:

Answer:

Cell growth usually refers to cell proliferation, the increase in cell numbers that occurs through repeated cell division. Cell growth can also refer to the enlargement of cell volume, which can take place in the absence of cell division. As living things grow, some cells die or become damaged and need replacements. Some single-celled organisms use a type of mitosis as their only form of reproduction. In multicellular organisms, cell division allows individuals to grow and change by expanding the number of total cells.

Explanation:

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

The orbitals 3f and 2d cannot exist.

Explanation:

Hello!

In this case, considering the attached picture in which you find each energy level with the corresponding number of subshells, it is possible to infer level one has s subshell only, level 2 s and p, level 3 has s, p and d and from level 4 to 7 have s, p, d f, therefore, the orbitals 3f and 2d cannot exist.

Answer:

3.1 × 10⁻⁵

Explanation:

The pH of a 0.53 M solution of 3-hydroxypropanoic acid (HC₃H₅O₃) is measured to be 2.39. Calculate the acid dissociation constant of 3-hydroxypropanoic acid. Be sure your answer has the correct number of significant digits.

Step 1: Given data

Step 2: Write the acid dissociation reaction

3-hydroxypropanoic acid is a weak acid that dissociates according to the following equation.

HC₃H₅O₃(aq) ⇄ C₃H₅O₃⁻(aq) + H⁺(aq)

Step 3: Calculate the concentration of H⁺

We will use the definition of pH.

pH = -log [H⁺]

[H⁺] = antilog -pH = antilog -2.39 = 4.07 × 10⁻³ M

Step 4: Calculate the acid dissociation constant (Ka) of 3-hydroxypropanoic acid

We will use the following expression.

Ka = [H⁺]² / Ca

Ka = (4.07 × 10⁻³)² / 0.53

Ka = 3.1 × 10⁻⁵

Explanation:

It will not float on water

Substances with their densities less than that of water usually float on it and those with their densities greater than that of water will sink into it.

From the question the density of glass is 2.8 g/cm³ and this is greater than the density of water which is 1 g/cm³. Therefore glass will not float on water.

Answer:

A Beryllium (Be) atom has 2 electron shells, whereas a Barium (Ba) atom has 6 electron shells

Explanation:

Beryllium (Be) is an element in group two of the periodic table with atomic number 4 (Is2 2s2). On the other hand, barium (Ba) is an element in group 2 of the periodic table with atomic number 56. However, as stated in the question, the Beryllium (Be) atom is smaller than the Barium (Ba) atom.

This is because a Beryllium (Be) atom has 2 electron shells, whereas a Barium (Ba) atom has 6 electron shells. The electron shells of Barium contains more electrons, which is responsible for the large size of the Barium atom. Note that, the higher the number of atoms, the larger the atomic size.

The pressure of the dry gas : 687.5 torr

Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases  

Can be formulated:  

P tot = P1 + P2 + P3 ....  

The partial pressure is the pressure of each gas in a mixture  

Since the gas mixture consists of He and H₂O :

P tot=P He + P H₂O

[tex]\tt 705=P~He+17.5\\\\P~He=705-17.5=687.5~torr[/tex]
