Which of these statements best explains why the ocean currents in the northern hemisphere tend to move in the clock-wise direction? (2 points) question 14 options: 1) the currents deflect to the right due to the rotation of earth. 2) the change in gravitational forces causes currents to move towards right. 3) the deflection of winds to the left causes the currents to move in the opposite direction. 4) the altered wind speed due to earth's rotation causes the movement of ocean water.

Enough of a monoprotic weak acid is dissolved in water to produce a 0.0172 m solution. if the ph of the resulting solution is 2.39 at 20 °c, determine the pka for the acid.

When curium-242 is bombarded with an alpha particle, two products are formed, one of which is a nudge on. what is the other product

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
