Answer: A solution with a pH of 7 must be neutral.
Explanation:
If a solution has pH of 7 then the concentration of 
ions and 
ions will be equal.
Thus, the concentration for both ions and ions will be 
. Generally, pH at 7 is considered as neutral.
Thus, it is concluded that a solution with pH of 7 must be neutral.
The law of multiple proportions is..
Different compounds made of same element have different proportions by mass of those elements.
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
