Answer:
The answer to your question is Sodium Perchlorate
Explanation:
Data
which is the salt?
Chemical reaction
Perchloric acid + Sodium hydroxide ⇒ Sodium perchlorate + Water
HClO₄ + NaOH = NaClO₄ + H₂O
Process
In inorganic chemistry there are two types of salts:
- Binary salts
- Oxysalts
Binary salts are inorganic compounds form by a metal and a nonmetal (only two compounds).
Oxysalts are inorganic compounds form by metal, a nonmetal, and oxygen (three elements).
In the reaction given the only compound that has these characteristics is Sodium perchlorate which is an oxysalt.
3) The density of the water depends on the amount of salt on the water, therefore it is the
dependent variable
<h3><u>Answer;</u></h3>
A. the reactants and the products.
<h3><u>Explanation</u>;</h3>
- The enthalpy of a reaction is the heat released or absorbed by a reaction at constant pressure.
- Enthalpy is important as it tells us the amount of heat energy present in a system. In chemical reactions it tells us the amount of heat energy lost or gained.
- <em><u>Changes in enthalpy are determined as the reactants are converted into products. Therefore, enthalpy depends on the reactants and the products. In other words it depends on the heat of reactants and that of products.</u></em>
