HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l)

A student was given the task of titrating a 20.mL sample of 0.10MHCl(aq) with 0.10MNaOH(aq). The HCl(aq) was placed in an Erlenmeyer flask. An equation for the reaction that occurs during the titration is given above. (a) According to the equation for the reaction, if the amount of the reactants is halved, how does this affect the amount of H2O(l) produced in the reaction?

According to the reaction equation shown,  if the amount of the reactants is halved, the amount of H2O(l) produced in the reaction will be halved.

The molecular reaction equation was given as follows; HCl(aq) + NaOH(aq)→ NaCl(aq) + H2O(l). Ionically, we can write; H^+(aq) + Cl^-(aq) + Na^+(aq) + OH^-(aq) > Na^+(aq) + + Cl^-(aq) + H2O(l). The net ionic equation now becomes; H^+(aq) + OH^-(aq) > H2O(l).

This implies that the concentration of H2O(l) depends on the concentrations of H^+(aq) and OH^-(aq) from HCl(aq) and NaOH(aq) respectively and the mole ratio of reactants and products is 1:1:1:1.

Hence, of the amount of the reactants is halved,  the amount of H2O(l) produced in the reaction will be halved.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
