Answer:
The dyes which cover more surface area will travel more slowly. Similarly if two substances which have same speeds, they are going to travel together and they won't separate as chromatography separates substances having different rates or speeds for travelling
Answer:
a) <u>Balanced Equation</u>
2NaCl (aq) + (NH₄)₂CO₃ (aq) → Na₂CO₃ (aq) + 2NH₄Cl (aq)
b) <u>Total Ionic Equation</u>
2Na⁺ (aq) + 2Cl⁻ (aq) + 2NH₄⁺ (aq) + CO₃ ²⁻ (aq) → 2Na⁺ (aq) + CO₃²⁻ (aq) + 2NH₄⁺ (aq) + 2Cl⁻ (aq)
c) <u>Net Ionic Equation</u>
All are spectator ions, so no net ionic equation.
Answer:
Q = 1.68 Kcal
Explanation:
∴ m H2O = 12.0 g
∴ T1 = 35°C ≅ 308 K
∴ T2 = 175°C ≅ 448 K
∴ ΔT = T2 - T1 = 175 - 35 = 140 °C
∴ Cp H2O = 1 cal /g.°C
⇒ Q = (12.0 g)(1 cal/g°C)(140 °C)
⇒ Q = (1680 cal)*(Kcal/1000 cal)
⇒ Q = 1.68 Kcal
True because you shouldn’t be selfish and share with the world
