Answer:
Its called the mean of the data.
Explanation:
Rising air in the tropics is called the Intertropical convergence zone and is a region of rising hot air. As it rises, the moisture in the air eventually reaches its saturation point and the moisture falls out as rain. This is why the tropics are know for their very heavy rainfall periods
I think the correct answer would be <span>requires energy as heat. From the Le Chatelier's principle, when a reaction needs energy to react, increasing the temperature would favor the reaction. This is called an endothermic reaction. Hope this answers the question.</span>
1) in periodic acid (HIO₄), iodine has oxidation number +7, hydrogen has oxidation number +1, oxygen has -2, compound has neutral charge:
+1 + x + 4 · (-2) = 0.
x = +7.
2) in molecule of iodine (I₂), iodine has oxidation number 0, because iodine is nonpolar molecule.
3) in sodium iodide (NaI), iodine has oxidation number -1, sodium has oxidation number +1:
+1 + x = 0.
x = -1.
4) in iodic acid (HIO₃), iodine has oxidation number +5, hydrogen has oxidation number +1, oxygen has -2, compound has neutral charge:
+1 + x + 3 · (-2) = 0.
x = +5.
Answer:
when there is a radical in the denominator, we should rationalize (mutiply the denominator and numerator by the radical) to get rid of the radical in the denominator.
