Answer:
1.023 J / g°C
Explanation:
Mass, m = 37.9 g
Temperature increase (change) = 25.0°C
Heat = 969 J
Specific heat capacity , c= ?
The relationship between these quantities is given by the equation;
H = mcΔT
c = H / mΔT
c = 969 / (37.9 * 25)
c = 969 / 947.5 = 1.023 J / g°C
Answer:
The value of y = 5.1478
Explanation:
The linear equation is an equation obtained when a linear polynomial is equated to zero. When the solution obtained on solving the equation is substituted in the equation in place of the unknown, the equation gets satisfied.
The given equation: 5.3 x 10- (y)(2y) = 0
⇒ 53 - 2y² = 0
⇒ 2y² = 53
⇒ y² = 53 ÷ 2 = 26.5
⇒ y = √26.5 = 5.1478
The salt contains ionic bond so that it dissociate ultimately by the movement of ion electricity is conducted
