Question

1. Вычислите количество вещества оксида бария, полученного при взаимодействии бария, количество вещества которого 8 моль с кислородом.

Answer 1

Ответ:

8моль

Объяснение:

8моль Х

2Ва + О2 = 2ВаО

2моль 2моль

Х=8*2/2=8моль

Answer 2

Calculating the Amount of Barium Oxide Produced

To calculate the amount of barium oxide produced when barium reacts with oxygen, we can use the balanced chemical equation for the reaction. The balanced chemical equation for the reaction between barium and oxygen is:

2 Ba + O2 → 2 BaO

From the balanced chemical equation, we can see that 2 moles of barium react with 1 mole of oxygen to produce 2 moles of barium oxide.

Given that the amount of substance of barium is 8 moles, we can calculate the amount of barium oxide produced using the stoichiometry of the reaction.

Using the stoichiometry of the reaction, we can calculate the amount of barium oxide produced as follows:

8 moles Ba × (2 moles BaO / 2 moles Ba) = 8 moles BaO

Therefore, when 8 moles of barium react with oxygen, 8 moles of barium oxide are produced.
