<span>Dalton noted that the chromium oxide molecules that he was studying had masses of oxygen that were not the same: he found that there were constant ratios to these mass differences, however, so there had to be some sort of "units" (atoms) making up the ratios of these particles.</span>

Leokris [45]

Ocean currents determine the various directions of wind movement.

<h3>What is ocean current?</h3>

Ocean currents are caused by differences in density as well as the temperature of the moving winds across the ocean. In the ocean, warm water is found at the top while cooler water occurs far below.

Warm ocean currents originate near the equator and move towards the poles. The ocean currents control the direction of winds in an area.

Which way does the water move once it reaches the water table
Mrrafil [7]

Answer:

Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere. Plants, too, help water get into the atmosphere through a process called transpiration...

OLEGan [10]

Answer:

Kp=9.2x10^{-3}

Explanation:

Hello!

In this case, for the undergoing chemical reaction at equilibrium:

2SO_2(g)+O_2(g)\rightleftharpoons 2SO_3(g)

Which means that pressure-based equilibrium constant is computed via the following equilibrium expression:

Kp=\frac{p_{SO_3}^2}{p_{SO_2}^2p_{O_2}}

Thus, by plugging in the given pressures at equilibrium, the required Kp turns out:

Kp=\frac{55.0^2}{70.2^2*66.7}\\\\Kp=9.2x10^{-3}

Best regards!
