Answer:

The correct answer choices are B and D.

Explanation:

A volcanic eruption happens when magma reaches the surface of the earth.  Depending on the amount of gas and the silica content of the magma, the lava and the type of eruption can vary.  Silica, which forms from the elements silicon and oxygen, <u>makes the lava thicker</u> and less runny. When lava is thick, the volcanic eruption tends to be more explosive.  The <u>amount of silica also changes the color</u> and density of the <u>lava</u>, which then makes different kinds of igneous rocks.  As the gas content of the lava goes up, the eruption becomes more explosive.

WHAT IS THE PERCENT BY VOLUME OF ETHANOL IN A SOLUTION THAT CONTAINS 35 mL ETHANOL IN 115 mL OF WATER?
Dmitry [639]
We need to first add both of the solution volumes together 35+115=150. Now we can divide the volume of the ethanol by the total volume 35/150=.233. To double check we can multiply the total volume by the percentage of ethanol by volume we got as a solution 150x.233=35. So the percentage by volume of ethanol in the solution is .233x100=23.3%.

In this experiment, 1-2 mL of saturated sodium chloride is used to transfer the crude product after the initial distillation. Wh
lina2011 [118]

<span>Saturated sodium chloride is used to transfer the product rather than water since it is not polar and rinsing the product with water would revert any 4-methylcyclohexene back to 4-methylcyclohexanol in the Hickman Head and thus lowering the percent yield; using water would shift the equilibrium towards the reactants.  Also sodium chloride removes the small amount of phosphoric acid and also a small amount of water.  If one were to add water, both 4-methylcyclohexene and phosphoric acid are partially soluble making difficult to remove the water later; sodium chloride makes the water less reactive so easier to remove by making the aqueous later more polar.</span>
