Understanding how much of a product is produced in a reaction is referred to as ________ understanding the reaction?

1 answer:

7 0

Hello!

Understanding how much of a product is produced in a reaction is referred to as Stoichiometrically understanding the reaction.

Stoichiometry is the calculation of the quantitative relationships between reactants and products in a chemical reaction. The first to talk about stoichiometry was Jeremias Benjamin Ritcher, who said that "Stoichiometry is the science that measures the quantitative proportions or mass ratios of chemical elements that are involved in a chemical reaction".

To calculate how much of a product is produced in a reaction, Stoichiometry is used, applying the law of conservation of mass. That means that the amount of product can be calculated from the amounts of reactants if they are known.

7. Indicate if the following are correct or incorrect.

solong [7]

Answer:

1s2: correct.

6s3: incorrect because the subshell s can hold up to 2 electrons.

5f10: correct.

4d3: correct.

2d4: incorrect because the second energy level just has the s and p subshells.

3p10: incorrect because the p subshell can hold up to 6 electrons.

Explanation:

Hello there!

In this case, according to the attached file, which shows the correct orbitals and electrons, we can proceed as follows:

1s2: correct.

6s3: incorrect because the subshell s can hold up to 2 electrons.

5f10: correct.

4d3: correct.

2d4: incorrect because the second energy level just has the s and p subshells.

3p10: incorrect because the p subshell can hold up to 6 electrons.

Using water and the reagents provided in the lab, create two solutions such that when you mix equal amounts together, the result

Bingel [31]

Here’s one of many possibilities.

We MUST know the heat of reaction, ΔH, before we start .

Let’s assume that the reaction is

A + B → Products; ΔH = -80 kJ·mol⁻¹

Let’s assume that you want to get 100 mL of solution that warms from 25 °C to 50 °C.

For the solution

q = mcΔT = 100 g × 4.184 J·K⁻¹mol⁻¹ × 25 K = 10 460 J = 10.46 kJ

The reaction must supply 10.46 kJ.

For the reaction

nΔH = 10.46 kJ

n = 10.46 kJ/80 kJ = 0.131 mol

So, you need 0.131 mol A and 0.131 mol B.

Assume you are using the 3 mol·L⁻¹ solutions.

Then

V = 0.131 mol × (1 L/3 mol) = 0.0436 L = 46.6 mL

You need 46.6 mL of 3 mol·L⁻¹ A + 46.6 mL of 3 mol·L⁻¹ B.

Add 3.4 mL distilled water to 46.6 mL of 3 mol·L⁻¹ A to make 50 mL of A.

Add 3.4 mL distilled water to 46.6 mL of 3 mol·L⁻¹ B to make 50 mL of B.

Mix the two solutions, and you will have 100 mL of a solution at 50 °C .

Calcula cuanto costara tener encendido toda la noche (8horas) un radiador de 2500w sabiendo que el precio del Kwh es de 15 centi

Varvara68 [4.7K]

Answer:

300 centavos

Explanation:

De la pregunta anterior, se obtuvieron los siguientes datos:

Potencia (P) = 2500 W

Tiempo (t) = 8 horas

Costo de operación =?

A continuación, convertiremos 2500 W a KW. Esto se puede obtener de la siguiente manera:

1000 W = 1 KW

Por lo tanto,

2500 W = 2500 W × 1 KW / 1000 W

2500 W = 2,5 KW

Por tanto, 2500 W equivalen a 2,5 KW

A continuación, determinaremos la energía consumida. Esto se puede obtener de la siguiente manera: Potencia (P) = 2,5 KW

Tiempo (t) = 8 horas

Energía (E) =?

E = Pt

E = 2,5 × 8

E = 20 KWh

Finalmente, determinaremos el costo de operación. Esto se puede obtener de la siguiente manera:

1 KWh = 15 centavos

Por lo tanto,

20 KWh = 20 KWh × 15 centavos / 1 KWh

20 KWh = 300 centavos

Por lo tanto, costará 300 centavos tener un radiador de 2500 W encendido toda la noche (8 horas).
