Answer:

La masa de Bi (NO₃) ₃ producida es de aproximadamente 2.117,09 gramos

Explanation:

La ecuación química de la reacción se presenta como sigue;

2Mn (NO₃) ₂ + 5NaBiO₃ + 14HNO₃ → 2HMnO₄ + 5Bi (NO₃) ₃ + 5NaNO₃ + 7H₂O

La masa dada de Mn (NO₃) ₂ = 650 g

La masa de NaBiO₃ = 750 g

El número de moles de Mn (NO₃) ₂ = 650 g / (178.95 g / mol) ≈ 3.63 moles

El número de moles de NaBiO₃ = 750 g / (279.968 g / mol) ≈ 2.68 moles

Por lo tanto, el NaBiO₃, es el reactivo limitante, y el rendimiento teórico de Bi (NO₃) ₃ ≈ 5/2 × 2.68 = 6.7 moles

Dado que la eficiencia del proceso es del 80%, el rendimiento real de Bi (NO₃) ₃ = 0,8 × 6,7 moles = 5,36 moles de Bi (NO₃) ₃

La masa molar de Bi (NO₃) ₃ ≈ 394,98 g / mol

La masa de Bi (NO₃) ₃ = 394,98 g / mol × 5,36 moles ≈ 2,117,09 g

La masa de Bi (NO₃) ₃ produjo ≈ 2,117.09 g

If the reaction was reversed and we wanted to produce as much NaN3, in grams, as possible from 30.0 g of N2 and 20.0 g of Na, wh
Valentin [98]

Answer:

N₂

Explanation:

Sodium is a larger molecule with a much higher molecular weight. However, 20g of N₂ would be a smaller amount of molecules than 20g of sodium due to how there are multiple nitrogen molecules.

2/3 * given mass of N₂ = mass of N₃

N₃ (Azide ion) given mass = 20g

Na = 20g

Masses of chemicals are equal

Na = 22.990g/mol

20g/22.990g/mol = 0.8699mol of Na

N₃ = 20g

N₃ = N g/mol x 3

N = 14.007 g/mol

14.007 x 3 = 42.021 g/mol

N₃ = 42.021g/mol

20g/42.021g/mol = 0.4759 mol of N₃

Notice how there are fewer moles of the Azide ion than the Sodium.

0.4759 moles of NaN₃ is produced

combine molecular weights:

42.021 + 22.990 = 65.011 g/mol

multiply by amount of moles of the limiting reactant:

0.4759 mol *65.011 = 30.942 g

Also, here is the balanced equation:

3N₂ + 2Na = 2NaN₃

The results are the same as the balanced equation.

How does an embryo develop from a fertilized egg?]
faltersainse [42]

Answer: Hope this helps

<h3>Explanation: <u><em>The fertilized egg zygote divides repeatedly as it moves down the fallopian tube to the uterus. First, the zygote becomes a solid ball of cells. ... Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.</em></u></h3><h3><u><em /></u></h3>
