<span>KNO3 is a strong electrolyte because it completely dissociates into ions in water. Dissociates means it immediately breaks into ions of K+ (potassium cation) and NO3- (nitrate anion). Thus it also conducts electricity very well compared to a weak electrolyte.</span>
Answer:
87.3 calories of heat is required.
Explanation:
Heat = mcΔT
m= mass, c = specific heat of silver, T = temperature
H= 57.8 g * 0.057 cal/g°C * ( 43.5 - 17 °C)
H = 57.8 * 0.057 * 26.5
H = 87.3069 cal.
The heat required to raise the temperature of 57.8 g of silver from 17 °C to 43.5 °C is 87.3 calories.
