Lesson 1 Key Questions 1. Mg2+ has 10 electrons 2. Given that the half life of the radioisotope carbon -14 is 5730 years‚ it would not be useful in dating bones that are over a million years old. After 40 000 years of age less than 1% of the 14C is left in the bone and thus it is not useful for determining the exact age beyond that. 3. Hydrolysis - A chemical reaction where a chemical is broken down by a reaction with water. Hydrolysis is important for the digestion of food‚ making

Q1. Various digital-to-digital encoding techniques are as follows: a) Signal spectrum – a transmission contains lack of high frequency components which means less bandwidth is required and direct current component is also desirable. With no dc component‚ ‘ac’ coupling via transformer is possible. Finally‚ the magnitude of the effects of signal distortion and interference depend on the spectral properties of the transmitted signal. b) Clocking – to provide a separate clock lead to synchronize the
