According to thermodynamics
Its D as A, B and C are physical properties of water
Answer:
- <u>25.0 liter of nitrogen gas</u>
Explanation:
<u>1. Chemical equation</u>
Ammonium nitrite is a solid compound that decomposes into nitrogen gas and water vapor as per this chemical equation:
<u>2. Mole ratio</u>
<u>3. Volume ratio</u>
Since, both species are gases and are at same temperature and pressure, the volume ratio is equal to the mol ratio.
Thus, the volume ratio is:
<u>4. Use the volume ratio with the known amount of water produced</u>
Answer:
An excellent experiment is to heat sodium thiosulfate in a water bath. The solid crystals will dissolve into the water in the hydrated crystals forming a supersaturated solution. ... Placing a small crystal in the supersaturated solution will cause the liquid to turn solid.
Balanced equation :
Cu(NO₃)₂(aq) + 2KOH(aq) → Cu(OH)₂(s) + 2KNO₃(aq)
Balancing a chemical equation :
A chemical equation shows us the substances involved in a chemical reaction - the substances that react (reactants) and the substances that are produced (products). In general, a chemical equation looks like this:
Reactant →Product
According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants. Therefore, the amount of the atoms in each element does not change in the chemical reaction. As a result, the chemical equation that shows the chemical reaction needs to be balanced. A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.
