Molar mass :

NH₃ = 17.0 g/mol

(NH₄)₂SO₄ = 132 g/mol

2 NH₃ + H₂SO₄ = (NH₄)₂SO₄

2 x 17 g NH₃ ------------ 132 g <span> (NH</span>₄)₂SO<span>₄
</span>( mass NH₃) ------------ 1.90 x 10⁵ <span> (NH</span>₄)₂SO<span>₄

( mass NH</span>₃) = (1.90 x 10⁵) x 2 x 17 / 132
<span>
( mass NH</span>₃) = 6460000 / 132
<span>
( mass NH</span>₃) = 48939.39 g
<span>
in kg :

48939.39 / 1000 = 48.93 kg = 4.893 x 10</span>¹ kg
<span>
hope this helps!

34kurt

Answer:

Estos elementos se denominan metales de transición, metales pesados, elementos del bloque D, etc.

Explanation:

Aquí, en esta pregunta, queremos saber la razón por la cual hay un espacio de 10 elementos entre el calcio, que es un elemento del grupo dos, y el galio, que es un elemento del grupo 3.

Al observar la tabla periódica, la tabla periódica moderna, notamos un bloque de elementos entre los elementos del grupo 2 y los elementos del grupo 3 en la tabla periódica.

Entonces, ¿por qué se colocan estos elementos entre ambos grupos? Se colocan aquí porque no pertenecen en su totalidad al grupo 2, ni tampoco al grupo 3.

Estos elementos presentan una especie de estados de oxidación variables que son responsables de una amplia variedad de propiedades comunes entre ellos.

Practice: How many protons, neutrons and electrons are in the following?
Nata [24]

Answer:

The answer to your question is below

Explanation:

When we have the number of an element followed by a number, that number is the atomic mass.

Atomic mass is the number of protons plus neutrons.

                              Protons                    Neutrons

Carbon-13                  6                            13 - 6 = 7

Chromium-51            24                          51- 24 = 27

Strontium-88             38                           88 - 38 = 50

Boron-10                     5                            10 - 5 = 5
