Answer:
An impurity is something that ruins the uncontaminated nature of something. If someone accuses you of impurity, they think you or your nature has been spoiled in some way by sin. When water is pure, the only thing in that water is water.
Answer:
2H⁺ (aq) + 2OH⁻ (aq) → 2H₂O (l)
General Formulas and Concepts:
- Solubility Rules
- Strong Acids/Bases
Explanation:
<u>Step 1: RxN</u>
HNO₃ (aq) + Ca(OH)₂ (aq) → Ca(NO₃)₂ (aq) + H₂O (l)
<u>Step 2: Balance RxN</u>
2HNO₃ (aq) + Ca(OH)₂ (aq) → Ca(NO₃)₂ (aq) + 2H₂O (l)
<u>Step 3: Ionic Equations</u>
Total Ionic Equation:
2H⁺ (aq) + 2NO₃⁻ (aq) + Ca²⁺ (aq) + 2OH⁻ (aq) → Ca²⁺ (aq) + 2NO₃⁻ (aq) + 2H₂O (l)
<em>Cancel out spectator ions.</em>
Net Ionic Equation:
2H⁺ (aq) + 2OH⁻ (aq) → 2H₂O (l)
Answer:
Explanation:
Given data:
Mass of mixture = 454 kg
Initial temperature is 10°C
Heat added is Q = 121300 kJ
Heat capacity (Applesuace) at 32.8°C is 4.02kJ/kg K
From heat equation we have
Putting all value to get required final temperature value
