Answer:

3.34 M

Explanation:

Step 1: Given data

Step 2: Calculate the moles of acetic acid

The molar mass of acetic acid is 60.05 g/mol.

100 g × 1 mol/60.05 g = 1.67 mol

Step 3: Calculate the molarity of acetic acid

The molarity is equal to the moles of solute divided by the liters of solution.

M = n/V

M = 1.67 mol/0.5000 L = 3.34 M

Explanation:

If we compare its solubility products without any calculation then, Magnesium hydroxide is more soluble than compound A and C. Magnesium hydroxide is less soluble than compound D.

- The solubility product of magnesium hydroxide and zinc carbonate is same so it is not possible to determine whether it is more or less soluble than compound B

Answer:

C. One type of atom is oxidized and another is reduced

D. Electrons are transferred from one atom to another

Explanation:

just took the test, i hope this helps!!

have a nice day and take care of yourself!! :))

One type of atom is oxidized and another is reduced and  Electrons are transferred from one atom to another. Therefore, the correct options are options C,D.

Any chemical process in which a participating chemical species' oxidation number changes is known as an oxidation-reduction reaction, often known as a redox reaction. The phrase refers to a broad range of processes. Numerous oxidation-reduction processes are as frequent and well-known as fire, metal corrosion and disintegration, fruit browning, respiration, and photosynthesis—basic life processes.

The combined processes of oxidation and reduction are known as redox reactions due to their complimentary nature. The oxidising agent is the reactant that causes the oxidation, while the reducing agent itself reduces this reagent.  One type of atom is oxidized and another is reduced and  Electrons are transferred from one atom to another.

Therefore, the correct options are options C,D.

Answer:

Cathode: Mn → Mn²⁺  +  2e⁻    (Oxidation)

Anode: Zn²⁺  +  2e⁻  →  Zn   (Reduction)

Mn | Mn²⁺ ||  Zn²⁺  | Zn

Explanation:

To identify the half reaction we need to see the oxidation states.

Mn(s) → Ground state → Oxidation state = 0

Mn(NO₃)₂ → Mn²⁺  → The oxidation state has increased.

This is the oxidation reaction. It has released two electrons:

Mn → Mn²⁺  +  2e⁻

Zn(NO₃)₂ →  Zn²⁺

Zn → Ground state → The oxidation state was decreased.

This is the reduction reaction. It has gained two electrons:

Zn²⁺  +  2e⁻  →  Zn

Cathode: Mn → Mn²⁺  +  2e⁻

Anode: Zn²⁺  +  2e⁻  →  Zn

Mn | Mn²⁺ ||  Zn²⁺  | Zn

Answer:

[tex]\boxed {\boxed {\sf 0.127 \ mol \ Au}}[/tex]

Explanation:

To convert from mass to moles, the molar mass must be used. This can be found on the Periodic Table.

Use this number as a ratio.

[tex]\frac {196.96657 \ g\ Au }{1 \ mol \ Au}[/tex]

Multiply by the given number of grams.

[tex]25.0 \ g \ Au*\frac {196.96657 \ g\ Au }{1 \ mol \ Au}[/tex]

Flip the fraction so the grams of gold will cancel.

[tex]25.0 \ g \ Au*\frac {1 \ mol \ Au}{196.96657 \ g\ Au }[/tex]

[tex]25.0*\frac {1 \ mol \ Au}{196.96657 }[/tex]

[tex]\frac {25.0 \ mol \ Au}{196.96657 }[/tex]

[tex]0.1269250919 \ mol \ Au[/tex]

The original measurement has 3 significant figures, so the answer must have the same. For the number we calculated that is the thousandth place. The 9 in the ten thousandth place tells us to round the 6 to a 7.

Answer:

Radio waves are able to penetate the earth's atmosphere due to their low frequency and long wavelength.

Let me know if this helps!

Answer:

The frequency of the electromagnetic wave is 7.22891566 × 10¹⁴ Hz

Explanation:

The wavelength of the electromagnetic wave, λ = 415 nm

The speed of an electromagnetic wave, c ≈ 3.0 × 10⁸ m/s

Given that an electromagnetic wave is a periodic wave, we have;

The speed of the electromagnetic wave, c = f×λ

Where;

f = The frequency of the electromagnetic wave

Therefore, we have;

f = c/λ

From which we have;

f = (3.0 × 10⁸ m/s)/(415 nm) = 7.22891566 × 10¹⁴ /s = 7.22891566 × 10¹⁴ Hz

The frequency of the electromagnetic wave, f = 7.22891566 × 10¹⁴ Hz

Answer:

a. The gas with the highest average molecular speed is the gas option 3.

b, The gas that has the lowest average molecular speed is the gas option 1.

c. The gas with average molecular speed between the highest and the lowest is the gas sample, option 4

Explanation:

From the kinetic theory of gases we have;

[tex]v_{rms} = \sqrt{\dfrac{3\cdot R\cdot T}{m} }[/tex]

Where;

[tex]v_{rms}[/tex] = The root mean square velocity of the gas

T = Temperature of gas in Kelvin

m = Mass of atom or molecule in kilograms

R = The universal gas constant

Therefore, [tex]v_{rms}[/tex] ∝ T and [tex]v_{rms}[/tex] ∝ 1/m

a. Therefore, the gas with the highest average molecular speed has the highest temperature, 'T', and the lowest mass, 'm', therefore, we have;

The gas with the highest average molecular speed is the gas option 3. with only 0.128 moles of Ne in 5.69 L container at a temperature of 426 K

b. The gas with the lowest average molecular speed has the lowest temperature, 'T', and the highest mass, 'm', therefore, we have;

The gas with the lowest average molecular speed is the gas option 1. with only 0.564 moles of Ne in 5.33 L container at a temperature of 308 K

c. The gas with an average molecular speed between the highest and the lowest is the gas with intermediate temperature and mass within the given gas samples

Therefore, the gas with the average molecular speed between the highest and lowest is the gas option 4. with 0.322 moles of Ne in 4.00 L container at a temperature of 398 K

Among these options, the correct formula for calcium phosphide is D. [tex]CaP_2[/tex]. Option D

The product formed from a reaction between calcium (Ca) and phosphorus (P) is calcium phosphide, which is represented by the chemical formula [tex]Ca_3P_2[/tex].

In the reaction between calcium and phosphorus, the calcium atom (Ca) donates two electrons to each phosphorus atom (P). This results in the formation of calcium ions (Ca2+) and phosphide ions (P3-). The ions combine to form the compound calcium phosphide ([tex]Ca_3P_2[/tex]).

The formula [tex]Ca_3P_2[/tex]indicates that three calcium atoms combine with two phosphorus atoms. The numerical subscripts are determined by the charges of the ions involved. Calcium, being a group 2 element, forms ions with a +2 charge (Ca2+), while phosphorus, being a group 15 element, forms ions with a -3 charge (P3-).

The product options provided are:

A. [tex]Ca_3P_2[/tex]

B. Cap

C. [tex]CazP_2[/tex]

D. [tex]CaP_2[/tex]

Among these options, the correct formula for calcium phosphide is D. [tex]CaP_2[/tex].

Answer:

4.2 Liters (2 sig-figs)

Explanation:

Apply Boyles Law ... P₁V₁ = P₂V₂

P₁ = 712 Torr      P₂ = 3560 Torr

V₁ = 21.0L           V₂ = ?

P₁V₁ = P₂V₂ => V₂ = P₁V₁/P₂ = (712Torr)(21.0L)/(3560Torr) = 4.2 Liters (2 sig-figs)

Answer:

1. Dynamic equilibrium is a equilibrium in which the rate of forward direction is equal to the rate of backward direction. It is represented by a right left arrow.

2) Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_c[/tex]  

For the given chemical reaction:

[tex]Fe^{3+}(aq)+SCN^-(aq)\rightleftharpoons [Fe(SCN)]^{2-}(aq)[/tex]

The expression for [tex]K_c[/tex] is written as:

[tex]K_c=\frac{[[Fe(SCN)]^{2-}]}{[Fe^{3+}][SCN^-]}[/tex]

3) The value of [tex]K_c[/tex] is 1000 , which means the products are more favoured as compared to reactants and that the equilibrium lies more towards product side.

Answer:

0.2 mole

Explanation:

From the question given above, the following data were obtained:

Number of molecules = 12.06×10²²

Number of mole =?

From Avogadro's hypothesis,

6.02×10²³ molecules = 1 mole

Therefore,

12.06×10²² molecules = 12.06×10²² / 6.02×10²³

12.06×10²² molecules = 0.2 mole

Thus, 12.06×10²² molecules is equivalent to 0.2 mole
