Question

При взаимодействии 9,6 грамм оксида металла (III) с серной кислотой образуется 24 грамма сульфата металла (III). Определите металл.

Answer 1

Me2O3+3H2SO4--> Me2(SO4)3 + 3H2O
Сначала выразим кол-во вещества оксида и сульфата(масса Me=x):
9.6/48+2x
24/288+2x
Приравняем их (коэффициент 1:1, поэтому ничего не добавляем)
9.6/48+2х=24/288+2х
далее решаем:
9.6(288+2х)=24(48+2х)
2764.8+19.2х=1152+48х
28.8х=1612.8
х=56
Ищем в таблице Менделеева элемент с такой массой... и.. о чудо! нашелся наш герой - Fe(железо)

Answer 2

Determining the Metal from the Reaction

When 9.6 grams of a metal oxide (III) reacts with sulfuric acid to produce 24 grams of the metal sulfate (III), we can use this information to determine the metal involved in the reaction.

The molar mass of the metal oxide (III) can be calculated using the given mass of the oxide and the molar mass of the sulfate formed. From the reaction, we can deduce the following:

1. The molar mass of the metal oxide (III) is 9.6 g. 2. The molar mass of the metal sulfate (III) is 24 g.

To determine the metal involved, we can calculate the molar mass of the metal oxide (III) and compare it with the molar mass of various metal oxides to find a match.
