Answer:
(a)False (b)False (c)False (d)False (e)False
Explanation:
a) Continuous time signal can also be digital. e.g continuous time square waveform (see first picture)
b) A discrete time signal can also be analog. e.g discrete time exponential function can take any value (see second picture)
c) When both energy and power of signal are infinite, it is neither power signal nor energy signal e.g ramp signals, 
signal
d)A signal of infinite length can also have finite energy. e. g
e)Step waveform u(t) is a power signal but also causal
First, we write the reaction equation:
NiCO₃ + 2HBr → NiBr₂ + H₂CO₃
Now, writing this in ionic form:
NiCO₃ + 2H⁺ + 2Br⁻ → NiBr₂ + 2H⁺ + CO₃⁻²
(NiCO₃ is insoluble so it does not dissociate in to ions very readily)
Overall equation:
NiCO₃ + 2Br⁻ → NiBr₂ + CO₃⁻²
