A. An identification of the atoms in a molecule
Explanation:
The chemical formula of a compound is a representation which shows all the elements therein and the mole relationship between them expressed as subscripts.
Therefore, a chemical formula allows us to identify atoms that are within a molecule.
A molecule is a covalent compound that has discrete or separate units.
For example;
HCl represents 1 mole of hydrogen chloride molecules consisting of 1 mole of hydrogen atoms and 1 mole of chlorine atoms.
Answer:
La réponse ce trouve en bas
Explanation:
13 a) Oui, ce possible parce la solubilité du sel dans l'eau a 60° est majeur que 50g du sel en 150 ml d'eau (333.3 g/L). Dans la graphique la solubilité est de 370 g/L.
b) Jusqu'au 30°C, (30°, 360g(L), ce trouvent ces points dans la ligne rouge.
