Anurse needs 525 g of 2.00 % sterile saline solution (nacl). she has two sterile stock solutions of nacl: 5.000% and 0.5000 % by mass, but no sterile water. how much of the 5.000 % and the 0.5000 % solutions he needs to make the required solution? (a) 150 g of the 5.000 % solution and 375 g of the 0.5000 % solution (b) 175 g of the 5.000 % solution and 350 g of the 0.5000 % solution (c) 185 g of the 5.000 % solution and 340 g of the 0.5000 % solution (d) 200 g of the 5.000 % solution and 325 g of the 0.5000 % solution

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.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
