Answer:
El volumen del cuerpo es el mismo al comienzo de la experiencia.
Explicación:
El volumen del cuerpo es el mismo al principio porque el volumen no cambia si la temperatura permanece igual. Si cambiamos la temperatura i. mi. Al aumentar la temperatura, las moléculas comienzan a expandirse y se produce un aumento de volumen mientras que cuando disminuimos la temperatura, las moléculas de esa sustancia comienzan a contraerse y el volumen de esa sustancia disminuye. Entonces concluimos que el volumen depende de la temperatura.

Answer:
The reaction between hydrogen and fluorine.
Explanation:
The balanced chemical equation of the reaction is:
From the balanced chemical equation, it is clear that:
1 mole of 
gas reacts with one mole of 
and forms 2 moles of HF(g).
Answer:
It organizes all of the elements and it allows you to easily find the groups of elements such as
Group 1 of the periodic table consists of hydrogen and the alkali metals
Group 2 consists of the alkaline metals (batteries!)
Groups 3–12 contain transition metals
Groups 13–16 each contain at least one metalloid
Group 17 contains halogens
Group 18 consists of noble gases which are stable.
