Answer:
sodium
Explanation:
this is because sodium is neutral ....hence the pH formed will be 7
Answer:The product and reactants reach a final, unchanging level.
Using a more concentrated HCl solution and Crushing the CaCO₃ into a fine powder makes the reaction to occur at a faster rate.
<u>Explanation:</u>
CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + H₂O(aq) + CO₂(g)
When calcium carbonate reacts with hydrochloric acid, it gives out carbon-dioxide in the form of bubbles and there is a formation of calcium chloride in aqueous medium.
The rate of the reaction can be increased by
- Using a more concentrated HCl solution
- Crushing the CaCO₃ into a fine powder
When concentrated acid is used instead of dilute acid then the reaction will occur at a faster rate.
When CaCO₃ is crushed into a fine powder then the surface area will increases thereby increasing the rate of the reaction.
4 x 10 to the 3rd power mg = 4000 Mg.
Explanation:
The interatomic and the intermolecular. Interatomic Unions: They are those that are established between the atoms. There are three types. In two of them, the so-called Ionic and Covalent, the atoms try to

Las interatómicas y las intermoleculares. Uniones Interatómicas: Son las que se establecen entre los átomos. Hay de tres tipos. En dos de ellas, las llamadas Iónicas y Covalentes, los átomos tratan de llegar a completar el último nivel con ocho electrones cumpliendo con la clásica teoría del octeto de Lewis.
