Ionic or covalent C2H5OH

Afina-wow [57]

Answer:

Covalent

Explanation:

A molecule of C₂H₅OH has C-C, C-H, C-O, and O-H bonds.

A bond between A and B will be ionic if the difference between their electronegativities (ΔEN) is greater than 1.6.

$\begin{array}{ccc}\textbf{Bond} & \textbf{$\Delta$EN} & \textbf{Polarity}\\\text{C-C} & 2.55 - 2.55 = 0.00 & \text{Nonpolar covalent}\\\text{C-H} & 2.55 - 2.20 = 0.35 & \text{Nonpolar covalent}\\\text{C-O} & 3.44 - 2.55 = 0.89 & \text{Polar covalent}\\\text{O-H} & 3.44 - 2.20 = 1.24 & \text{Polar covalent}\\\end{array}$

No bond has a large enough ΔEN to be ionic.

C₂H₅OH is a covalent molecule.

What is the percent composition of chromium in CrCl3?

maks197457 [2]

The oxidation state of Chromium chloride (III) is +3

How can we find the answer?

First of all write down what you know about the molecule:

1: The molecule hasn't got an electric charge (is not an ione), this means that either positive and negative charges of its atoms are balanced (we have the same number of positve and negative charges)

2: Since it's a salt, where the metal is chromium and the non metal is the alogen Chlorine, we know that the negative charge belogns to the non metal element because of its elettronegativity, therefore the positive charge belongs to the metale element (chromium).

3: when chlorin forms binary salts its oxidation state is always -1 (you can find out this info in a periodic table)

In CrCl3 we have 3 chlorine atoms where each of them carrys 1 negative charge, so the total amount of negative charges is -3

Since the charges are balanced, the question is: Which is the positive charge that Chromium must carry in order to balance 3 negative charges?

The answer comes out to +3

Consider the following expression:8.30 x 10^-5 = x(0.100 + x)^2We can solve for x using a technique called successive approximat

Black_prince [1.1K]

Answer:

a. x3 and x4 are the first to agree to two significant figures

b. x4 and x5 are the first to agree to three significant figures

Explanation:

8.30 x 10⁻⁵ = x1(0.100)²

8.30 x 10⁻⁵ = 0.01x1

x1 = 8.30 x 10⁻⁵/0.01 = 0.0083

8.30 x 10⁻⁵ = x2(0.100 + 0.0083)²

8.30 x 10⁻⁵ = (0.01172889)x2

x2 = 8.30 x 10⁻⁵/0.01172889

x2 = 0.007076543475128

8.30 x 10⁻⁵= x3 (0.100 + 0.007076543475128)²

8.30 x 10⁻⁵ = 0.011465386162581)x3

x3 = 8.30 x 10⁻⁵/0.011465386162581

x3 = 0.007239180505832

8.30 x 10⁻⁵ = x4 (0.100 + 0.007239180505832)²

8.30 x 10⁻⁵ = (0.011500241835562) x4

x4 = 8.30 x 10⁻⁵/0.011500241835562

x4 = 0.007217239531723

8.30 x 10⁻⁵ = x5 (0.1 + 0.007217239531723)²

8.30 x 10⁻⁵ = (0.011495536452803) x5

x5 = 8.30 x 10⁻⁵/0.011495536452803

x5 = 0.007220193710904

From the above results;

a. x3 and x4 are the first to agree to two significant figures

b. x4 and x5 are the first to agree to three significant figures

If 3.0 moles of x and 4.0 moles of y react according to the hypothetical reaction below, how many moles of the excess reactant w

Umnica [9.8K]

Answer is: 1.0 mol X left over.
Chemical reaction: X + 2Y → XY₂.
n(X) = 3,0 mol, excess reactant.
n(Y) = 4,0 mol, limiting reagent.
n - amount of substance.
from reaction: n(X) : n(Y) = 1 : 2.
n(X) : 4 mol = 1 : 2.
n(X) = 2 mol, that reacts.
excess of X: 3 mol - 2 mol = 1 mol.
