vampirchik [111]

Answer: Oxygen is the limiting reagent.

Explanation: $CS_2(l)+3O_2(g)\rightarrow CO_2(g)+2SO_2(g)$

As can be seen from the given balanced equation:

3 moles of $O_2$ reacts with 1 mole of $CS_2$

1.52 moles of $O_2$ reacts with= $\frac{1}{3}\times 1.52=0.51moles$ of $CS_2$

Thus $O_2$ is the limiting reagent as it limits the formation of products. (0.91-0.51)= 0.40 moles of $CS_2$ will remain as such and thus $CS_2$ is an excess reagent.

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.
