The answer is c) Electrical energy
Answer: A physical change is a change that can be undone.
Explanation: An example of this is mixing red blocks, green blocks, and blue blocks. You can easily separate them.
Answer:
0.5 M
Explanation:
First, let us look at the balanced equation of the reaction.
The solute formed is .
Recall that: mole = molarity x volume
Hence,
50 ml, 1.00 M H2SO4 = 0.05 x 1 = 0.05 mole
50 ml, 2.0 M KOH = 0.05 x 2 = 0.1 mole
From the equation
<em>1 mole of H2SO4 reacts with 2 moles of KOH to give 1 mole of K2SO4.</em>
Hence,
<em>0.05 mole H2SO4 reacting with 0.1 mole KOH will give 0.05 mole </em><em>.</em>
Also recall that: concentration = mole/volume
Total volume of resulting solution = 50 ml + 50 ml = 100 ml or 0.1 liter
Concentration of = mole of /volume of resulting solution
= 0.05/0.1 = 0.5 M
The concentration of the resulting solute = 0.5 M
Answer: choose a.
1. Iodine monochloride
2. Bromine pentafluoride
3. Tricarbon disulfide
4. Tetranitrogen tetrasulfide
a. The balanced chemical equation is: Zn+2HCl→ZnCl2+H2.
b. The overall reaction is: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
c. The spectator ion is: zinc
d. The net ionic equation is: Zn ₅ + 2H⁺ (aq) → Zn ²⁺ (aq) + H₂ (g)
<h3>What are Spectator ions?</h3>
Spectator ions are ions that are present in chemical processes but do not take part in them and are the same on both sides of the reactions. The spectator ions are cancelled from both sides of the equation in the net chemical reaction.
<h3>What is the definition of ionic reactions?</h3>
In general, ionic reaction occurs when anions and cations combine to generate a compound in a liquid or solid media. Water-insoluble salts are created when the ions of salts that are soluble in water interact with one another.
