Ionic compound is formed by negative and positive ions, these ions form ionic bond
Hello friend ☺
ΔH = MCΔT
ΔH = to the amount of energy or change in energy (J)
mass of water
C = waters specific heat capacity
ΔT = change in temperature
and so ΔH = 25 × 4.18 × ( 112-67 ) J = 4702.5 J
Thanks ❤
Homogeneous Reactions. At equilibrium, the rate of the forward and reverse reaction are equal, which is demonstrated by the arrows. The equilibrium constant, however, gives the ratio of the units (pressure or concentration) of the products to the reactants when the reaction is at equilibrium.
I think it’s A I’m not 100% sure but I mean it’s worth a try
43 degrees
angle of reflection is equal to the angle of incidence
