Name the two geometrical isomer of hydrocarbon

Answer:

I think the answer might be yes..

Answer:

A

Explanation:

I would expect a gas to diffuse through another gas faster because gases generally diffuse much faster than liquids. Hence, A is the best option.

The change in vapor pressure when 74.10 g fructose, C6H12O6, are added to 181.5 g water is 0.146.

Vapor pressure is the  measure or tendency of  a substance to change into a vapor or gaseous state.

[tex]\rm Mole\; fraction\; of\; water = \dfrac{nH_2O}{nH_2O+npent.}[/tex]

Calculate the moles of water and fructose

[tex]\rm Number\;of \;moles= \dfrac{181.5 g}{18.02}= 10.072\\\\\rm Number\;of \;moles= \dfrac{74.10 g }{180.156 g/mol}=0.4113[/tex]

The total number of moles are

[tex]\dfrac{10.072}{10.072 + 0.486} = \dfrac{10.072}{10.558} = 0.953[/tex]

Calculating the vapor pressure

0.953 x 3.1690 kPa = 3.023

Change in vapor pressure

3.1690 kPa - 3.023 = 0.146

Thus, the  change in vapor pressure is 0.146.

Answer:

0.50 Molar or 0.50 Mol/L

Explanation:

Molarity = [tex]\frac{Moles of Solute}{Litres of solution}[/tex]

Molarity = n / V

Given: Volume of solution(V): 1.75 Litres

Moles of solute(n): 0.877

Substituting values,

Solution:

Molarity = [tex]\frac{0.877}{1.75}[/tex]

Molarity = 0.50 Molar (rounded off to the nearest decimal place)

∴ Molarity = 0.50 Molar/ 0.50 Mol/L

Answer: 2.749 x 10^-14

Explanation:

Given:

The concentration of Ce(IO3)4 in the solution = 1.5 x 10-2 g/100 mL= 0.15 g/1000 mL​​​​​​​= 0.15 g/L

Molar mass of Ce(IO3)4 = 839.7267 g/mol

Therefore, the molarity of Ce(IO3)4 in the solution is given by:

[tex]$$\begin{gathered}M=\frac{0.15 \mathrm{~g} / L}{839.7267 \mathrm{~g} / \mathrm{mol}} \\M=1.7863 \times 10^{-\mathbf{4}} \mathrm{mol} / {L}=\mathbf{1 . 7 8 6 3 \times 1 0 ^ { - \mathbf { 4 } } \boldsymbol { M }}\end{gathered}$$[/tex]

The solubility equilibrium is given by:

[tex]$$\mathrm{Ce}\left(\mathrm{IO}_{3}\right)_{4(s)} \rightleftharpoons \mathrm{Ce}_{(a q)}^{3+}+3 \mathrm{IO}_{3}^{-}(a q)$$[/tex]

Therefore, the solubility product is given by:

[tex]\begin{gathered}K_{s p}=\left[C e^{3+}\right] \cdot\left[I O_{3}^{-}\right]^{3} \\\therefore K_{s p}=\left(1.7863 \times 10^{-4}\right) \times\left(3 \times 1.7863 \times 10^{-4}\right)^{3}\end{gathered}[/tex]

[tex]\therefore {K_{s p}=2.749 \times 10^{-14}[/tex]

Answer:

Carbon has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.

Answer:

5.09 moles of Fe is required to react with 3.82 moles of O₂.

0.326 moles of O₂ are needed to produce 34.7 grams of Fe₂O₃.

Reaction stoichiometry

In first place, the balanced reaction is:

4 Fe + 3 O₂ → 2 Fe₂O₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Fe: 4 moles

O₂: 3 moles

Fe₂O₃: 2 moles

The molar mass of the compounds is:

Fe: 55.85 g/mole

O₂: 32 g/mole

Fe₂O₃: 159.7 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

Fe: 4 moles ×55.85 g/mole= 223.4 grams

O₂: 3 moles ×32 g/mole= 96 grams

Fe₂O₃: 2 moles ×159.7 g/mole= 319.3 grams

Moles of Fe needed

The following rule of three can be applied: If by stoichiometry of the reaction 3 moles of O₂ react with 4 moles of Fe, 3.82 moles of O₂ react with how many moles of Fe?

moles of Fe= 5.09 moles

Finally, 5.09 moles of Fe is required to react with 3.82 moles of O₂.

Moles of O₂ needed

The following rules of three can be applied: If by reaction stoichiometry 319.3 grams of Fe₂O₃ are formed from 3 moles of O₂, 34.7 grams of Fe₂O₃ are formed from how many moles of O₂?

moles of O₂= 0.326 moles

Finally, 0.326 moles of O₂ are needed to produce 34.7 grams of Fe₂O₃.

Cheap energy

Explanation:

Fossil fuels such as coal, oil, and gas are widely available and are much cheaper than other forms of energy (wind, nuclear, etc.) Fossil fuel products are also quite efficient, as the efficieny of fossil fuels is about 50% (which is actually really good), while solar panels for example are only about 15% efficient.

According to the research, levers are used to modify or generate a force and transmit displacement.

It is a simple machine composed of a rigid bar of some moderately resistant material, which rotates freely on a support point.

It can be used to maximize the mechanical force applied to an object, increasing its speed or the distance it travels, by applying a proportionally smaller amount of force.

Therefore, we can conclude that according to the research, levers are used to modify or generate a force and transmit displacement.

Answer:

B. Spectator ions

Explanation:

Spectator ions are described as spectators literally because they "spectate", or, in other words, do not participate in the overall reaction. They may show up in the reaction equation, but they don't react themselves.

Thus, spectator ions stay unchanged throughout a reaction. We see many spectator ions in precipitation reactions. Remember that ionic compounds disassociate in solution.

For example, the reaction between silver nitrate [tex]AgNO_{3}[/tex] and sodium chloride [tex]NaCl[/tex] produces a solid precipitate of silver chloride [tex]AgCl[/tex] as represented by the equation below:

[tex]Ag^+_{(aq)} + NO^-_{3(aq)}+Na^+_{(aq)}+Cl^-_{(aq)}[/tex] -------> [tex]AgCl_{(s)}+Na^+_{(aq)}+NO_{3(aq)}^-[/tex]

However, the sodium and nitrate ions remained aqueous, like before, so they did not react. Thus, they are spectator ions.

Explanation:

The pressure of the N₂ collected if the temperature was 22°C celcius is 98.6823 kPa.

What is atmospheric pressure?

The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure.

Atmospheric pressure = 101.325 kPa

Vapor pressure of water at 22°C = 2.6427 kPa

Pressure of N₂ = (Atmospheric pressure) - (vapour pressure of water at 22°C)

Pressure of N₂ = (101.325 kPa) - ( 2.6427 kPa)

Pressure of N₂ = 98.6823 kPa

Therefore, the pressure of the N₂ collected if the temperature was 22°C celcius is 98.6823 kPa.

Moles are the ratio of grams to the grams per mole. There are 12 moles of oxygen after dissociation.

Dissociation is the release of the ions, cations, and anions of the molecular compound in the water. The dissociation of the compound is shown as:

Mn₆(ClO₄)₃  ⇆  6 Mn³⁺ + 3ClO⁴⁻

From the dissociation, it can be said that 1 mole of magnesium chlorate dissociates into 12 moles of oxygen atoms.

Given, that the moles of the compound is 1 mole.

Then moles of oxygen atom will be: 1 × 12 = 12 moles

Therefore, 12 moles of oxygen atoms are produced from the dissociation of the compound.
