A reaction yield 6.26 g of a product what is the percent yield if the theoretical yield is 18.81 g

Answers

Answer 1

Explanation:

remember the equation percentage yield = actual/theoretical yield

so 6.26/18.81 X 100 gives u 33.28017012 so to 3 SF ot would be 33.3%

hope this helps:)

Answer 2

The statement, that describes the percent yield is 33.280 g.

What is percent yield?

The percent yield is the ratio of actual yield to theoretical yield. It is computed by dividing the experimental yield by the theoretical yield and multiplying the result by 100 percent. If the actual and theoretical yields are equal, the percent yield is one hundred percent.

To express the efficiency of a reaction, use the following formula: percent yield

= (actual yield/theoretical yield) x 100

= (6.26 g/ 18.81 g) x 100

= 33.280 g

Hence the correct answer is 33.280 g.

Un átomo neutro tiene número atómico 1 y número másico 3. Indica cuántos protones, neutrones y electrones tiene.

Answers

Answer:

El átomo podes 1 protón, 1 electrón y 2 neutrones.

Explanation:

Cada elemento químico se caracteriza por el número de protones de su núcleo, que se denomina número atómico Z. Es decir, el número atómico​ de un elemento químico es el número total de protones que tiene cada átomo de ese elemento.

Los protones poseen carga positiva y se encuentran en el núcleo, en torno al cual se mueven otras partículas con carga eléctrica negativa que son los electrones. Así, el átomo es eléctricamente neutro, ya que la carga positiva de los protones está compensada por la carga negativa de los electrones.  Entonces, en todo átomo neutro el número de protones del núcleo es igual al de electrones de sus orbitales.

En este caso, un átomo neutro tiene número atómico 1. Entonces la cantidad de protones y electrones presentes en el átomo es 1.

En el núcleo de cada elemento, además de protones, también es posible encontrar neutrones, cuyo número puede variar. La masa atómica (A) se obtiene sumando el número de protones y de neutrones de un núcleo determinado:

Número másico (A) = número de protones + número de neutrones

En este caso, el átomo neutro posee 1 protón y su número másico es 3. Entonces:

3= 1 + número de neutrones

Resolviendo:

3 - 1= número de neutrones

2= número de neutrones

Entonces, el átomo podes 1 protón, 1 electrón y 2 neutrones.

How many atoms are in 5.9 g of N2?

Answers

Answer:

Number of atoms in 5.9 g of N2 = 1.268 *10^23

Explanation:

Weight of one mole of N2 is 28.0134 g

In one mole of N2, number of atoms = 6.023 *10^23

Number of atoms in 28.0134 g (one mole) of N2 =  6.023 *10^23

Number of atoms in 1 g of N2 = 6.023 *10^23/28.0134

Number of atoms in 5.9 g of N2 = 6.023 *10^23/28.0134 * 5.9

= 1.268 *10^23

A student measured the pH of his soda and found it to be 4.5.


Calculate the [H3O+] in the soda.

Answers

Explanation:

pH = 4.5

[H3O+] = ?

Relationship between both quantitiesis given by:

pH = -log₁₀ [H3O+]

-pH = log₁₀ [H3O+]

-4.5 =  log₁₀ [H3O+]

[H3O+]  = e ^ (-4.5)

Find the number of grams in 16.95 mol hydrogen peroxide (H2O2). Round your
answer to two decimal places and be sure to include the proper units.

Answers

Answer: There are 576.46 number of grams present in 16.95 mol hydrogen peroxide [tex](H_{2}O_{2})[/tex].

Explanation:

Number of moles is defined as the mass of substance divided by its molar mass.

The molar mass of [tex]H_{2}O_{2}[/tex] is 34.01 g/mol. Hence, mass of hydrogen peroxide present in 16.95 moles is calculated as follows.

[tex]Moles = \frac{mass}{molarmass}\\16.95 mol = \frac{mass}{34.01 g/mol}\\mass = 576.46 g[/tex]

Thus, we can conclude that there are 576.46 number of grams present in 16.95 mol hydrogen peroxide [tex](H_{2}O_{2})[/tex].

In this case, according to the given information, it is possible for us to realize that we need to use the ideal gas equation in order to calculate the volume of CO2 but firstly calculating the moles:

[tex]n=\frac{12.5g}{44.01g/mol}=0.284mol[/tex]

Then, we proceed with the ideal gas equation to solve for volume:

b) Weeding is the process of growing weed.
c) Weeding is the process of removal of weeds.
d) Weeding is usually done manually or by using weedicides.

Answers

Answer:

b) Weeding is the process of growing weed

Explanation:

Wedding is an agricultural process carried out to ensure maximum you won't do. It is the process by which weeds i.e. unwanted plants are removed.

As rightly stated in the question;

- Weeding is either done by manual means e.g Cutlasses or use of weedicides, which are chemicals.

- Weeding is best done during tiling operations.

The incorrect option is that "Weeding is the process of growing weed" rather it is a process of removing weed.

An electric kettle uses electrical energy to boil water. Energy from the electricity is transferred to the water, heating it up. An electric ice maker also uses electrical energy, but it freezes water to form ice. Since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice, what happens to the energy put into the ice maker and the energy released by the water?

Answers

Answer:

Since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice. The energy remains electrical but then changes to kinetic when Enough energy is released.

Explanation:

Answer:

Explanation:

The overabundance of electrical energy acquired by water during the ice framing process is taken out as likely energy to keep up with the law of energy conservation. The electrical energy given to the ice generator pivots the engine inside the blower (compressor). The coolant available inside the blower is compressed and this pressure is accomplished alongside the creation of heat energy. The heat energy is delivered into the external encompassing air of the ice generator. This prompts a drop in the temperature of the coolant.

This coolant courses inside the ice generator and soaks heat energy (heat stream from the heater to the colder area) from the water as it gets once again to the blower, Thus prompting cooling of water and development of ice.
