For a solution of H2SO4, determine the van\'t Hoff factor assuming 0% ionization and 100% ionization
Aleks [24]
The van't Hoff factor is the ratio between the amount of particles produced when a substance is dissolved and the amount of substance being dissolved. If ionization is 0 percent then it would mean that the substance do not dissociate into particles so the van't Hoff factor would be 1. However, when the percent ionization is 100%, then it fully dissociates into ions. For H2SO4 at 100% ionization, the vant hoff factor should be three, two hydrogen ions and one sulfate ion.

A 1.83 mol sample of carbon reacts with excess zinc oxide to produce zinc and carbon dioxide. How many moles of zinc oxide are c
dusya [7]

Answer:

3.66 moles of Zinc Oxide are consumed

Explanation:

Based on the reaction:

C + 2ZnO → 2Zn + CO₂

<em>Where 1 mole of Carbon reacts with 2 moles of Zin Oxide to produce 2 moles of Zinc and 1 mole of Carbon Dioxide.</em>

<em />

To solve this question, we must convert the moles of carbon added to the moles of Zinc Oxide that react using the chemical equation (1mol C = 2mol ZnO):

1.83 moles C * (2mol ZnO / 1mol C) =

<h3>3.66 moles of Zinc Oxide are consumed</h3>

Why would a person could jump further on moon than on Jupiter?
Tomtit [17]
In short, because the moon is smaller, its gravitational force is too. Therefore, if there is less gravity, it would be easier to jump further than on a bigger planet like Jupiter.

Explanation:
The Moon has less mass than the world, which implies it's less gravity than the world further.

Since the gravity is not propulsion on the U.S. as powerfully on the moon because it is on Earth, we are able to jump higher and with a lot of<span> ease.
</span>That's as a result of<span> our muscles (and all </span>alternative<span> body </span>elements concerned<span>, like our bones and joints and heart and lungs) all were developed and conditioned </span>to figure within the<span> stronger gravity on </span>the surface<span>.</span>
