Answer:

the difference between the two. Inference: Inference is something that uses facts to determine other facts. ... Inference can be accurate or inaccurate, justified or unjustified, logical or illogical. Conclusion: A conclusion is the next logical step in the information series.

Explanation:

Inferences and conclusions from that analysis can be powerful tools for understanding people and the decisions that they make. An inference is an assumed fact based on available information. A drawn conclusion is an assumption developed as a next logical step for the given information.

A chemist uses hot hydrogen gas to convert chromium(III) oxide to

Darya [45]

Answer: 3.024 g grams of hydrogen are needed to convert 76 grams of chromium(III) oxide, $Cr_{2}O_{3}$

Explanation:

The reaction equation for given reaction is as follows.

$Cr_{2}O_{3} + 3H_{2} \rightarrow 2Cr + 3H_{2}O$

Here, 1 mole of $Cr_{2}O_{3}$ reacts with 3 moles of $H_{2}$ .

As mass of chromium (III) oxide is given as 76 g and molar mass of chromium (III) oxide $(Cr_{2}O_{3})$ is 152 g/mol.

Number of moles is the mass of substance divided by its molar mass. So, moles of $Cr_{2}O_{3}$ is calculated as follows.

$No. of moles = \frac{mass}{molar mass}\\= \frac{76 g}{152 g/mol}\\= 0.5 mol$

Now, moles of $H_{2}$ .given by 0.5 mol of $Cr_{2}O_{3}$ is calculated as follows.

$0.5 mol Cr_{2}O_{3} \times \frac{3 mol H_{2}}{1 mol Cr_{2}O_{3}}\\= 1.5 mol H_{2}$

As molar mass of $H_{2}$ is 2.016 g/mol. Therefore, mass of $H_{2}$ is calculated as follows.

$No. of moles = \frac{mass}{molar mass}\\1.5 mol = \frac{mass}{2.016 g/mol}\\mass = 3.024 g$

Thus, we can conclude that 3.024 g grams of hydrogen are needed to convert 76 grams of chromium(III) oxide, $Cr_{2}O_{3}$ .

What are quantum numbers?

Quantum numbers are used to describe where around a nucleus a particular electron can be found.
In any given atom, each electron can be described by four quantum numbers.
These are n,l,m1,ms
The values that each number can be are based on a set of rules.

What is a magnetic quantum number ?

It describes the orientation of the orbitals.
It is represented as ml.
The value of this quantum number ranges from (-l to +l).
When l = 2, the value of will be -2, -1, 0, +1, +2.
