Answer:
single replacement reaction
Explanation:
This is a kind of single replacement reaction where you switch either cations or anions. Here you switched Ca for H and produced Cacl2 and H2 gas by itself.
Answer:
When sodium chloride dissolves in water to make a saturated solution there is a 2.5 per cent reduction in volume. ... The solubility of salt does not change much with temperature, so there is little profit in using hot water.
One electron in an atom experiences the entire positive charge of the nucleus. Coulomb's law can be used in this situation to determine the effective nuclear charge.
In contrast, the outside electrons in an atom with many electrons are drawn to the positive nucleus and repelled by the negatively charged electrons at the same time. The force between two stationary, electrically charged particles can be measured using Coulomb's law inverse-square law, also known as Coulomb's law. Conventionally, the electric force between two charged objects at rest is referred to as the Coulomb force or electrostatic force.
The electron is a subatomic particle with the symbol e or with an electric charge of one elementarily negative charge. The lepton particle family's first generation includes electrons.

Yes, it is a correct approach because endothermic reactions absorb heat. In consequence, the amount of heat can be used to classify this reaction.
<h3>Endothermic and exothermic reactions</h3>
An exothermic reaction is a type of chemical reaction that releases heat, thereby increasing the temperature of its surrounding environment.
Conversely, an endothermic reaction can absorb heat, thereby cooling its surrounding environment.
In consequence, the amount of heat measured after the reaction can be indicative of the type of chemical reaction.
