...if you use magnetso this is a mixture
p/s: or this is physical process
sorry if I'm wrong
Na₂S₂O₃(aq) + 2HCl(aq) → 2NaCl(aq) + H₂O(l) + SO₂(g) + S(s). A light yellow precipitate develops as the process continues.
<h3>What does the chemistry term "equation" mean?</h3>
Reaction equation are symbolic depictions of chemical reactions where the reactants and products are stated in relation to the following chemical formulae.
<h3>Equation and response are what?</h3>
What is an equations and a chemical reaction? In a chemical change, bonds between molecules of the reagent are destroyed and new bonds between molecules of the product are established to create a new substance. A chemical formula is nothing more than a statement of fact that represents how reactants generate products.

Answer:
5.67x10²³ ions
Explanation:
By looking at the molecular formula, we can tell that there are three Sr²⁺ ions per Sr₃(PO₄)₂ molecule.
We <u>convert Sr₃(PO₄)₂ moles into Sr₃(PO₄)₂ molecules</u> by using<em> Avogadro's number</em>:
- 0.314 moles * 6.023x10²³ = 1.89x10²³ molecules
Finally we <u>multiply that number by 3</u> in order to <em>convert Sr₃(PO₄)₂ molecules to Sr²⁺ ions</em>:
- 1.89x10²³ * 3 = 5.67x10²³ ions.
1. 100 C
2. Point B to C is the ices heat capacity
3. During the points D to E the bonds of the water molecules build up enough kinetic energy to break their intermolecular bonds (not intra), which can lead to gas.
4. Between points D and E the energy is being released the energy required is equivalent along the line.
5. Between point E and D the water is converting to water (condensation)
6. Energy is being released 2260 j/g
7. Yes, but only under extreme volumetric pressures
8. D and E or B and C
9. Freezing (the water is also becoming less dense)
10. Melting or if water already, absorbtion of energy
11. released.
