please helppp
which one??????????

Answer:

A & B

Explanation:

The answer for the first one is A because the proton is found in the nucleus with the neutron

The answer for the second was is B because the Neutrons, protons and electrons are all subatomic particles, as they are the main particles that make up an atom.

Proton = Positive Charge (+)

Neutron = Neutral charge (=)

Electron = Negative Charge (-)

Answer:

1- positive

2- A

3-A

Answer:

heating up, lol

Explanation:

The diagram best shows the field lines around two particles with opposite charges is the third diagram. Therefore, option C is correct.

A graphic tool for viewing vector fields is a field line. It is made up of a fictitious directed line that is perpendicular to the field vector over its whole length.

Among many other sorts, they are employed to display magnetic, electric, and gravitational fields. In the study of fluid mechanics, streamlines are field lines that display the velocity field of a fluid flow.

The field lines are parallel to the charge's surface. Both the size of the charge and the quantity of field lines are proportional. The positive charge is where the field lines begin, and the negative charge is where they come to a conclusion.

Thus, option C is correct.

Answer:

Zn + 2HCl -----> ZnCl₂ + H₂

Explanation:

The balanced chemical equation for Zn with hydrogen is Zn + 2HCl ---> ZnCl₂+ H₂.

What is balanced chemical equation?

A balanced chemical equation is one in which number of reactant is equal to number of products. When Zinc reacts with hydrogen it will form zinc chloride and hydrogen gas.

Here, 1 molecules of hydrochloric acid are participating in the process, and 1 molecules of hydrogen are being created.

Therefore, The balanced chemical equation for Zn with hydrogen is Zn + 2HCl ---> ZnCl₂+ H₂.

Given the two half-reactions, what must be done in the next step before the reaction can be balanced?

Answer: Show the number of electrons being lost or grained.

Explanation:

For a two given half-reactions, before the reaction can be balanced determine the number of electrons being lost or grained.

A half reaction is either the oxidation or reduction reaction component of a redox reaction.

The half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction.

Thus, for a two given half-reactions, before the reaction can be balanced determine the number of electrons being lost or grained.

Answer:

They are organic

Answer:

ΔH>0, ΔS>0, and ΔG<0

Explanation:

Crystalline solid → Gas

using Gibbs equation

ΔG = ΔH - TΔS

as ΔG < 0 and ΔS > 0

ΔH - TΔS <0

ΔH < TΔS ⇒ΔH >0

This gives that ΔH will be Positive but it will be less than TΔS. So we need to provide some energy to convert crystalline solid into gas.

Answer: The final concentration of a solution is 0.350 M

Explanation:

According to the dilution law,

[tex]C_1V_1=C_2V_2[/tex]

where,

[tex]C_1[/tex] = concentration of concentrated acid solution = 12.0 M

[tex]V_1[/tex] = volume of concentrated acid solution = 35.0 ml

[tex]C_2[/tex] = concentration of diluted acid solution= ?

[tex]V_2[/tex] = volume of another acid solution= 1.20 L = 1200 ml

( 1L=1000ml)

Putting in the values:

[tex]12.0\times 35.0=C_2\times 1200[/tex]

[tex]C_2=0.350M[/tex]

The final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L is 0.350 M

One ion is represented in each block of the periodic tables. Hence option C is correct.

Periodic table is defined as a table with the chemical elements ordered by increasing atomic number, displaying the elements to show trends in their characteristics. The elements are arranged in the Periodic Table in accordance with their related chemical and physical characteristics. There are rows and columns in the table. The periodic table's vertical columns stand in for Groups. Periods are shown in the table as horizontal rows.

Ions are defined as any atom or collection of atoms that carries one or more electrical charges, either positive or negative. The positive ions are known as cation while the negative ions are known as anion. When an atom's number of protons and electrons is out of balance, ions are created.

Thus, one ion is represented in each block of the periodic tables. Hence option C is correct.
