Quest Check-In Interactivity: Tides and the Moon's Gravity
ides and the Moon's Gravity
4. The force of gravity, which pulls the moon and Earth toward each
other, also affects the ocean. The moon's gravity pulls a little more
strongly on the water nearest the moon. This causes a bulge of water,
and a Type text here.
tide occurs on
this side of Earth.
The moon's gravity also nulls Farth toward the

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. the values of phosphorous acid are 1.30 6.70 calculate the ph for each of the given points in the titration of 50.0 ml of 1.5 m h3po3(aq) with 1.5 m koh(aq) .

What three things determine the shape and size of a puddle when water is poured out onto a surface
