Asmall cube of lithium (density = 0.535 g/cm3) measuring 1.0 mm on each edge is added to 0.550 l of water. the following reaction occurs: 2li(s)+2h2o(l)→2lioh(aq)+h2(g) part a what is the freezing point of the resulting solution? assume full dissociation of strong electrolytes and negligible solubility of hydrogen gas in water. the molal freezing-point-depression constant for water is 1.86°c/m.

What best describes a sonar wave? transverse and electromagnetic transverse and mechanical longitudinal and electromagnetic longitudinal and mechanical

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
