Answer: 2. The rubbish is separated first by hand, then through flotation (separating plastic and paper), magnets, and an eddy current method, which pings off aluminium and other metals. A laser beam identifies each type of plastic as it passes on a conveyor belt, then a timed jet of air pushes it into the appropriate bin. There are two broad types of recycling operations: internal and external. Internal recycling is the reuse in a manufacturing process of materials that are a waste product of that process. Internal recycling is common in the metals industry, for example. 3. Repurpose Glass, Plastic and Cardboard Containers.

Look at the reaction below.
Ray Of Light [21]

Answer:

Ca(OH)2 (aq)

Explanation:

The balanced neutralization reaction i.e. a reaction between an acid and a base, in this question is given as follows:

H2SO4(aq) + Ca(OH)2(aq) → CaSO4(aq) + 2H2O(l)

According to Arrhenius in his definition of acid and base, a base is a substance that dissociates into hydroxide ions (OH-) when in an aqueous solution. In other words, a base increases the concentration of hydroxide ions when dissolved.

In this reaction, Ca(OH)2 releases the OH- (hydroxide ion) that combines with the hydrogen ion (H+) released by the acid, H2SO4, to form water (H2O). Hence, Ca(OH)2 (aq) is the BASE.
