How would the balloons interaction with each other change if the balloons were moved further apart? Explain.

El ejercicio completo con las formulas es el siguiente:

cuál de las siguientes fórmulas no cumple con la tetravalencia del átomo de carbono.

a. CH3-CH2-CH2-OH

b. CH3-CH=CH2

c. CH3-CH2=CH2

d. CH3-CH2-CH3

Answer:

La respuesta correcta es la opción C

Explanation:

En la formula C, podemos ver claramente que no se cumple con la tetravalencia del carbono pues al sumar el total de las valencias del carbono nos da 5

CH3 - CH2  =   CH2 = Total de valencias del carbono 5

         1 + 2+  2   =  5

Para que la formula sea correcta debe eliminarse un hidrogeno quedando la formula de la siguiente manera:

                      CH3   -  CH   =   CH2

                                 1 +  1  + 2 =  4

The equation is balanced.

The number of P atoms in the reactant side is 4 and the number of P atoms in the product side is also 4.

The number of O atoms in the reactant side is 16 and the number of O atoms in the product side is also 16.

The number of H atoms in the reactant side is 12 and the number of H atoms in the product side is also 12.

These results are in accordance with the law of conservation of mass.

Answer:

8.72 × 10^5 moles

Explanation:

To find the number of moles in 5.25 x 10^29 molecules of sucrose, we divide the number of molecules by Avagadro constant (6.02 × 10²³ molecules). That is;

no. of moles = no. of molecules ÷ 6.02 × 10²³ molecules

In this case of sucrose, no of moles contained is as follows;

5.25 × 10^29 ÷ 6.02 × 10²³

5.25/6.02 × 10^ (29-23)

0.872 × 10^6

= 8.72 × 10^5 moles

Answer:

It is important for scientists to be repeatable so it lets them see patterns and trends in their results. This is affirmative for their work, making it stronger and better able to support their claims. This helps maintain The integrity of data.

Repeating an experiment more than once helps determine if the data was a fluke, or represents the normal case. It helps guard against jumping to conclusions without enough evidence. The number of repeats depends on many factors, including the spread of the data and the availability of resources

If 8 moles of FeS2 react with 15 moles of O2, the limiting reactant is O2.

4 moles of FeS₂ reacts with 11 moles of O₂

15 moles of O₂ is available. In comparison with 22 moles, O₂ is in short supply .

Therefore, If 8 moles of FeS2 react with 15 moles of O2, O₂ is the limiting reagent.

Explanation:

Los iones se forman cuando las especies químicas pierden o ganan electrones.

Las sustancias iónicas consisten en un ión positivo y negativo cuyas cargas se equilibran exactamente entre sí, por lo que el compuesto iónico es neutro.

Los átomos de metal se mantienen unidos por el enlace metálico. Esto implica la interacción entre iones metálicos cargados positivamente y un mar de electrones negativos. Las cargas positivas de los iones metálicos están exactamente equilibradas por el mar de electrones cargados negativamente, por lo que el metal es neutro.

This is because binary acids are molecular compounds in which hydrogen is combined with a non-metal element. Hydrochloric acid has hydrogen present in it's compound, therefore identifying it as the only binary acid amongst the answer choices.

Answer:

A. True

B. True

C. False

D. False

Explanation:

Electrons travel around the nucleus in circular orbits and moves from one orbit to another orbit when they absorb energy or lose energy. The Bohr atom is the model currently accepted for electrons in atoms because this model provides the right information about presence of electrons around the orbits. Scientists know the energies of electrons as well as the areas (orbitals) where the electrons are probably located with the help of new technology.

Answer:

By forming an activated complex with lower energy.

Explanation:

When catalyst is added to a reaction , it forms  an activated catalyst which has lower activation energy . So initiation of reaction requires less energy and reaction becomes fast .

Hence third option 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: The total energy, in kilojoules, that is needed to turn a 46 g block of ice at -25 degrees C into water vapor at 100 degrees C is 11.787 kJ.

Explanation:

Given: Mass = 46 g

Initial temperature = [tex]-25^{o}C[/tex]

Final temperature = [tex]100^{o}C[/tex]

Specific heat capacity of ice = 2.05 [tex]J/g^{o}C[/tex]

Formula used to calculate the energy is as follows.

[tex]q = m \times C \times (T_{2} - T_{1})[/tex]

where,

q = heat energy

m = mass

C = specific heat capacity

[tex]T_{1}[/tex] = initial temperature

[tex]T_{2}[/tex] = final temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times (T_{2} - T_{1})\\= 46 g \times 2.05 J/g^{o}C \times (100 - (-25))^{o}C\\= 11787.5 J (1 J = 0.001 kJ)\\= 11.787 kJ[/tex]

Thus, we can conclude that the total energy, in kilojoules, that is needed to turn a 46 g block of ice at -25 degrees C into water vapor at 100 degrees C is 11.787 kJ.

Answer: The oxidation state of Al in [tex]AlH_{3}[/tex] is +3.

Explanation:

The number attained by an atom or substance due to loss or gain of electrons is called oxidation state.

For example, in [tex]AlH_{3}[/tex] it is known that the oxidation state of hydrogen is -1 as aluminum is a cation so it cannot have an oxidation state as 'minus'.

Whereas hydrogen has the property to act both as a cation and an anion.

Let us assume the oxidation state of Al is x in the compound [tex]AlH_{3}[/tex].

Hence, oxidation state of Al is calculated as follows.

[tex]x + 3(-1) = 0\\x - 3 = 0\\x = +3[/tex]

This means that the oxidation state of Al in [tex]AlH_{3}[/tex] is +3.

Thus, we can conclude that oxidation state of Al in [tex]AlH_{3}[/tex] is +3.

Answer:

solute in a fixed volume of solution

Concentration(c) = number of moles of solute(n) / volume of solution (v)

25.0 mL of water is added to 125 mL of a 0.150 M LiOH solution and solution becomes more diluted.

original solution molarity - 0.150 M

number of moles of LiOH in 1 L - 0.150 mol

number of LiOH moles in 0.125 L - 0.150 mol/ L x 0.125 L = 0.01875 mol

when 25.0 mL is added the number of moles of LiOH will remain constant but volume of the solution increases

new volume - 125 mL + 25 mL = 150 mL

therefore new molarity is

c = 0.01875 mol / 0.150 L = 0.125 M

answer is 0.125 M
