CaCO₃ + 2HCl = CaCl₂ + CO₂ + H₂O
D. All of the Above (A, B, C)
Answer:
CuSO4(aq)
Explanation:
The aqueous for of CuSO₄ is an electrolyte and it will conduct electricity.
CuSO₄ is an ionic substance and in solid state, it will not have the ability to conduct electricity.
- In aqueous form, it will contain free mobile ions which serves as carriers of electric current.
- In the solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.
- The remaining given compounds will not conduct electricity as they are non-polar and do not have free mobile electrons.
<u>Ans: Volume of stock H2SO4 required = 6.94 ml</u>
<u>Given:</u>
Concentration of stock H2SO4 solution M1 = 18.0 M
Concentration of the final H2SO4 solution needed M2 = 2.50 M
Final volume of H2SO4 needed, V2 = 50.0 ml
<u>To determine:</u>
Volume of stock needed, V1
Explanation:
Use the dilution relation:
Answer: Salts
Explanation: Salts easily dissolve in water. Salts are always ionic bonds, meaning they dissolve easily.
Ice does not technically dissolve in water since ice is made of water. You can't dissolve a substance in itself.
Metals are obviously not able to dissolve either in water.
Oils do not mix with water, they float on water, meaning they are immiscible.
