when an antacid tablet dissolves in water, the fizz is due to a reaction between sodium hydrogen carbonate (sodium bicarbonate, nahco3) and citric acid (h3c6h5o7).
3 nahco3(aq) + h3c6h5o7(aq) 3 co2(g) + 3 h2o(l) + na3c6h5o7(aq)
how many moles of na3c6h5o7 can be produced if one tablet containing 0.0141 mol of nahco3 is dissolved?
mol

0.0047mol

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.
