Suppose you used the Procedure in this experiment to decompose 1.047 g of an lonic hydrate. You recovered 0.950 g of strontium oxalate (Src,0) after heating the sample to
constant mass
a) Determine the mass of water given off during heating,
b) Calculate the mass percent of water in the lonic hydrate.
c) Calculate the number of moles of an anhydrous compound in the sample.
d) Calculate the number of moles of water given off during heating.
e) Calculate the number of waters of hydration in the chemical formula for this lonic
hydrate

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.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
