Analytical chemistry -- A task that would fall into this area of chemistry is measuring the level of lead in drinking water.
Answer:
2 electrons from magnesium (Mg) is transferred to oxygen (O2) to form Mg2+ and O2-
which combines by strong electrostatic force to form MgO
the equation is
2Mg + O2 -> 2MgO
When water evaporates, its latent heat of evaporation absorbs heat.
<h3>What is Latent heat?</h3>
A body or thermodynamic system can release or absorb latent heat during a constant-temperature process, often a first-order phase transition.
There are two types of latent heat:
- The heat of freezing
- The heat of vaporization
The statements about water's latent heat and changes in state are:
- The heat of freezing is the quantity of thermal energy produced as a liquid freezes, and the heat of vaporization is the quantity of thermal energy needed to change a liquid into a gas.
- Water may move energy from one location to other thanks to latent heat.
- There aren't any weak (hydrogen) bonds between water molecules in the vapor state.
- Hurricanes are propelled by the latent heat of condensation, which occurs when water vapor condenses and turns into a liquid.
- All water molecules in the solid state are connected by flimsy (hydrogen) bonds.

Answer:
A neon lamp was switched on during the Great Depression and continued to burn until it was discovered some 77 years later. The electricity bill came up to a whopping $17 000!
