Explanation:

Answer: 55.7 moles of [tex]H_2O[/tex] are needed to produce the given amount of [tex]H_2[/tex]

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] ......(1)

Given values:

Moles of [tex]H_2[/tex] = 55.7 moles

The chemical equation for the decomposition of water follows:

[tex]2H_2O\rightarrow 2H_2+O_2[/tex]

By the stoichiometry of the reaction:

If 2 moles of hydrogen gas is produced from 2 moles of water

So, 55.7 moles of hydrogen gas will be produced by = [tex]\frac{2}{2}\times 55.7=55.7mol[/tex] of water

Hence, 55.7 moles of [tex]H_2O[/tex] are needed to produce the given amount of [tex]H_2[/tex]

Taking into account the reaction stoichiometry,

In first place, the balanced reaction is:

2 H₂O → 2 H₂ + O₂

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:

The following rule of three can be applied: if by reaction stoichiometry 2 moles of H₂ are produced from 2 moles of H₂O, 55.7 moles of H₂ are produced from how many moles of H₂O?

[tex]moles of H_{2} O=\frac{55.7 moles of H_{2}x 2 moles of H_{2} O}{2 moles of H_{2}}[/tex]

moles of H₂O= 55.7 moles

Finally, 55.7 moles of H₂O is requiredto produce 55.7 moles of H₂.

Answer:

5 moles

Explanation:

First, write out the balanced equation:

2Al + Fe₂O₃ → Al₂O₃ + 2Fe

Reaction ratio of Al to Fe₂O₃ is:

2 : 1

This means 2 moles of Al will react with 1 mole of Fe₂O₃

Al: 5 mol

Fe₂O₃: 3 mol

Multiply the reaction to get moles of both reactants you have:

2 : 1 (×⁵/₂) = 5 : ⁵/₂

2 : 1 (×3) = 6 : 3

In other words, 5 moles of Al will react with ⁵/₂ moles of Fe₂O₃;

And 3 moles of Fe₂O₃ will react with 6 moles of Al;

But, we do not have 6 moles of Al, therefore only the 5 moles of Al available will react;

5 moles of Al reacts with ⁵/₂ moles of Fe₂O₃, as we can see from the ratios we calculated above, the remaining ¹/₂ mole of Fe₂O₃ will not react;

We say that Al is the limiting reactant because all the Al will react but all the Fe₂O₃ does not (i.e. it is in excess);

Next and last, the reaction ratio of Al to Fe is:

2 : 2 or, more simply 1 : 1

This means the moles of Al that reacts is the equal to the moles of Fe produced from the reaction;

We've established that 5 moles of Al will react with ⁵/₂ moles of Fe₂O₃, so 5 moles of Fe will also be produced (since the ratio is 1 : 1);

You could also work this out using the moles of Fe₂O₃ that react;

The reaction ratio of Fe₂O₃ to Fe:

1 : 2

So the moles of Fe produced is 2× the moles of Fe₂O₃;

If ⁵/₂ moles of Fe₂O₃ reacts, then simply multiply this by 2 which is 5 moles

Answer:

The number of outermost energy level electrons ( valency electrons )

The atomic number

Answer:

Explanation:

Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.

Answer: The mass of water produced is 27 g

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] ......(1)

Given mass of pentane = 18 g

Molar mass of pentane = 72.15 g/mol

Plugging values in equation 1:

[tex]\text{Moles of pentane}=\frac{18g}{72.15g/mol}=0.250 mol[/tex]

The given chemical equation follows:

[tex]C_5H_{12}+8O_2\rightarrow 5CO_2+6H_2O[/tex]

By the stoichiometry of the reaction:

If 1 mole of pentane produces 6 moles of water

So, 0.250 moles of pentane will produce = [tex]\frac{6}{1}\times 0.250=1.5mol[/tex] of water

Molar mass of water = 18 g/mol

Plugging values in equation 1:

[tex]\text{Mass of water}=(1.5mol\times 18g/mol)=27g[/tex]

Hence, the mass of water produced is 27 g

In Order As A Food Chain

The elements are arranged into food chain like plants ⇒Mouse ⇒ Snake⇒ Hawk ⇒ Sun.

A substance that could not be further decomposed according to any chemical reaction is known as a chemical element.

The flow of nutrients as well as energy through such an ecosystem is described by a food chain. Energy is first produced by plants at the most fundamental level, and then it is used by higher-level species like herbivores. Energy is then transmitted from one carnivore to the next when they eat the herbivores.

Answer:

The spacing between the terrestrial planets is less than that between the gas planets.

Explanation:

Since the terrestrial planets which are Mercury, Venus, Earth and Mars have a distance of 0.4 AU, 0.7 A.U, 1.0 AU and 1.5 A.U respectively from while the gas planets which are Jupiter, Saturn, Uranus and Neptune have a distance of 5.2 AU, 9.6 AU, 19.6 AU and 30 AU respectively from the sun, we can see that the spacing between the terrestrial planets is much smaller than the spacing between the gas planets.

For example, the spacing between Mercury and Venus is 0.7 AU - 0.4 AU = 0.3 AU while that between Earth and Venus is 1.0 AU - 0.7 AU = 0.3 AU.

Also, the spacing between Earth and Mars is 1.5 AU - 1.0 AU = 0.5 AU.

Also too, the spacing between the gas planets is shown below  the spacing between Jupiter and Saturn is 9.6 AU - 5.2 AU = 4.4 AU while that between Uranus and Saturn is 19.6 AU - 9.6 AU = 10.0 AU.

Also, the spacing between Neptune and Uranus is 30 AU - 19.6 AU = 10.4 AU.

Thus, we can see that the spacing between the terrestrial planets is less than that between the gas planets.

Note that AU means astronomical unit and 1 AU is the distance between the Earth and the Sun. 1 AU = 1.50 × 10⁸ km

-3169 kJ/mol is the enthalpy of combustion when 1 mol [tex]C_6H_6(g)[/tex] completely reacts with oxygen.

Explanation:

Given:

The reaction of combustion of [tex]C_6H_6(g)[/tex] along with enthalpies of formation of the compounds.

To find:

The enthalpy of combustion when 1 mol [tex]C_6H_6(g)[/tex]  completely reacts with oxygen.

Solution:

[tex]2C_6H_6(g) + 15O_2(g) \rightarrow 12CO_2(g) + 6H_2O(g)[/tex]

Enthalpy of the reaction:

[tex]\Delta H^o_{rxn}=\sum [\Delta H^o_{f,products}]-\sum [\Delta H^o_{f,reactants}]\\=[12mol\times \Delta H^o_{f.CO_2(g)}+6mol\times \Delta H^o_{f,H_2O(g)}]-[2 mol\times \Delta H^o_{f.C_6H_6(g)}+15\times \Delta H^o_{f,O_2(g)}]\\=[12mol\times (-393.50 kJ/mol)+6mol\times (-241.82 kJ/mol)]-[2mol\times 82.90kJ/mol+15mol\times 0 kJ/mol]\\=-6338.72 kJ[/tex]

[tex]2C_6H_6(g) + 15O_2(g) \rightarrow 12CO_2(g) + 6H_2O(g).\Delta H^o_{rxn}=-6338.72 kJ[/tex]

When 1 mole of [tex]C_6H_6(g)[/tex]  reacts with oxygen gas:

[tex]=\frac{\Delta H^o_{rxn}}{\text{2 mol of } C_6H_6}\\=\frac{-6338.72 kJ}{2 mol}\\=-3169.36 kJ/mol\approx -3169 kJ/mol[/tex]

-3169 kJ/mol is the enthalpy of combustion when 1 mol [tex]C_6H_6(g)[/tex] completely reacts with oxygen.

Answer:

2Al(NO3)3+3K2CO3->Al2(CO3)3+6KNO3

So the right answer is 2,3,1,6

Explanation:

First you look at the equation that isn't balance, you can see Al(NO3)3 while Al2(CO3)3, so you put 2 in Al(NO3)3.

Now we have 2Al is correct, but 6NO3. So we have 6KNO3, it also means we have 6K

Finally, we only have 2K as K2CO3 so we put 3 in it, so we have 3K2CO3.

Sorry about my explanation, it's hard to understand but the answer is correct.

H₂ + ½O₂ → H₂O

2g → 18g

So, 18g water needs 2g H₂

So, 1g water needs 2/18g H₂

So, 180g water needs 2/18 x 180g H₂

→ 20 litres of H₂

Answer:

Explanation:

Molar mass of water, H2O = 2 + 16 = 18

So 180g of water contains 10M

H2 + O -> H2O

10M of Hydrogen is needed to produce 10M of water.

Molar volume at STP = 22.4L

So 10M of Hydrogen at STP = 224L

With Ideal Gas Law, P1V1/T1 = P2V2/T2

At STP, P1 = 1atm, T1=273K

At 0.97atm and 24c (273+24 = 297K), 10M of Hydrogen will take up:

1*224/273 = 0.97*V2/297

V2 = 224*297/273/0.97

= 251.23L

So the answer is 251.23L

Answer:

Yes

Explanation:

Yes, but almost insignificantly. The regular boiling point of water is 100 degrees celcius, adding a small handfull of salt will increase the boiling point to roughly 100.04 degrees celcius. Therefore, it is almost insignificant but still does affect it. This is mainly because salt changes the way the molecules react thus making it harder for them to change state from liquid to gas. This ultimately causes the water to get hotter before boiling actually occurs.
