Answer:

B

Explanation:

A

Explanation:

B is wrong because it talks about speed, C is wrong because it talks about direction, and D is wrong because it talks about the amount of tilt. A is correct because it's the only one that talks about the time of the orbit and the time of orbit determines the length of a year. :)

Answer:

Explanation:

Dynamic equilibrium only occurs in reversible reactions, and it's when the rate of the forward reaction is equal to the rate of the reverse reaction.

Answer:

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Explanation:

ZnS(s) + 2O₂(g) ⇒ZnSO₄(s)

The oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number

Oxidation is an increase in oxidation number, while reduction is a decrease in oxidation number.

Reaction

ZnS(s) + 2O₂(g) ⇒ZnSO₄(s)

S²⁻ (-2 in ZnS) to S⁺⁶(+6 in ZnSO₄) ⇒ oxidation

O₂(0 in O₂) to O⁻²(-2 in ZnSO₄)⇒ reduction

Carbon-12

Carbon-12 is the reference for all atomic mass calculations. An atomic mass unit is defined as a mass equal to one twelfth the mass of an atom of carbon-12.

pH=8.87

Reaction

C₂H₄O₂+NaOH⇒CH₃COONa+H₂O

at the equivalence point = mol C₂H₄O₂= mol NaOH

mol C₂H₄O₂ : 50 x 0.1 = 0.5 mlmol=5.10⁻⁴ mol

The two reactants have completely reacted, and there is only salt(CH₃COONa) and water(H₂O), there will be hydrolysis

For acids from weak acids and strong bases (the solution is alkaline) then the calculation:

[tex]\tt [OH^-]=\sqrt{\dfrac{Kw}{Ka}\times M }[/tex]

M=anion concentration=CH₃COO⁻

Ka=acid constant(for CH₃COOH,Ka=1.8.10⁻⁵)

[tex]\tt [OH^-]=\sqrt{\dfrac{10^{-14}}{1.8.10^{-5}}\times 0.1 }[/tex]

[tex]\tt [OH^-]=\sqrt{5.6.10^{-11}}=7.483\times 10^{-6}[/tex]

pOH=6-log 7.483=5.13

pH= 14 - 5.13=8.87

The pH of the solution is the negative log [H] concentration. The pH of the given solution is 8.87 at the equivalence point.

The given Reaction is:  

C₂H₄O₂+ NaOH ⇒ CH₃COON + H₂O

The pH of the solution can be calculated by,

[tex]\bold{pH = 14 - pOH}[/tex]................1

So first, calculate for pOH

[tex]\bold {pOH = \sqrt {\dfrac {Kw}{Ka} \times M}}[/tex]

Where,

Ka - dissociatioon constant = 50 x 0.1 = 0.5 ml = 5x10⁻⁴ mol

Kw - concentaion water ionic products = [tex]\bold {10^{-14}}[/tex]

M - anion concentration( CH₃COO⁻) = 0.1 M

Put the values in the formula,

[tex]\bold {pOH = \sqrt {\dfrac {\bold {10^{-14}}}{5\times 10^{-4} mol} \times 0.1}}\\\\\bold {pOH = 7.483 \times 10^{-6}}[/tex]

Since the pOH is the negative log of [OH⁻] concentration,

pOH = 6  -ln 7.483

pOH = 5.13

Put the value of pOH in the first equation,

pH= 14 - 5.13

pH = 8.87

Therefore, the pH of the given solution is 8.87 at the equivalence point.

We have that for the Question,it can be said that How much hydrogen chloride was used in the reaction is

From the question we are told

Magnesium (24.30g) reacts with hydrogen chloride (xg) to produce hydrogen gas(2.04g) and magnesium chloride (96.90g).

Generally the equation for the Reaction is  is mathematically given as

Mg+2HCl-----MgCl2+H2

Grams of MgCl2=[tex]\frac{96.9*24.30}{2.04}\\[/tex]
Grams of MgCl2=1154.25g

Answer:

10 protons

Explanation:

The atomic number of an element is equal to the number of protons of the element. The atomic number of neon is 10. Therefore, neon contains 10 protons.

10 protons are in the nucleus of one atom of neon based on this information found in the Periodic Table.

The chemical elements are arranged in rows and columns in the periodic table, sometimes referred to as the periodic table of the elements. It is frequently used in physics, chemistry, and other disciplines and is frequently regarded as a symbol of chemistry.

The elements are organized in what is known as the periodic table. Columns and rows are used to organize the table. The horizontal rows are referred to as "periods," while the vertical columns are known as "groups."

Thus, The atomic number of an element is similar to the number of protons of the element. The atomic number of an element neon is 10. So, neon contains 10 protons.
