Explanation:

Covalent compounds (solid, liquid, solution) do not conduct electricity. Metal elements and carbon (graphite) are conductors of electricity but non-metal elements are insulators of electricity. Ionic bonds are the electrostatic attraction between positive and negative ions.

Hope its useful... :-)

How many molecules of co2 in 97.3 grams of co2

s2008m [1.1K]

Answer:

1.33 × 10²⁴ molecules CO₂

General Formulas and Concepts:

Chemistry - Stoichiometry

Reading a Periodic Table
Dimensional Analysis
Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

Explanation:

Step 1: Define

97.3 g CO₂

Step 2: Define conversions

Avogadro's Number

Molar Mass of C - 12.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of CO₂ - 12.01 + 2(16.00) = 44.01 g/mol

Step 3: Convert

$97.3 \ g \ CO_2(\frac{1 \ mol \ CO_2}{44.01 \ g \ CO_2} )(\frac{6.022 \cdot 10^{23} \ molecules \ CO_2}{1 \ mol \ CO_2} )$ = 1.33138 × 10²⁴ molecules CO₂

Step 4: Check

We are given 3 sig figs. Follow sig fig rules.

1.33138 × 10²⁴ molecules CO₂ ≈ 1.33 × 10²⁴ molecules CO₂

When sulfuric acid and potassium hydroxide neutralize each other to make water and potassium sulfate, how is water formed?

statuscvo [17]

It's formed by the hydrogen ion of the acid and the hydroxide of the base.

$H_{2} SO_{4} + 2KOH --\ \textgreater \ K_{2} SO_{4} + 2H_{2}O$
Sulfuric Acid + potassium superoxide --> Potassium Sulfate + Heavy Water

Hope this Helps :)

The above reaction is run and found to follow second order kinetics with a rate constant of 1.30 x 10-3 M-1sec-1. If the initial

Leya [2.2K]

The final concentration after 172 seconds is 1.15 M. To obtain this answer, use the the integrated rate law for the order of reaction. Based on the problem, this is a second order reaction. The units of the rate constant also support that it is a second order reaction.

Further Explanation:

The solution to this problem is straightforward.

Identify the integrated rate law for the corresponding order of reaction.
Substitute the given values into the integrated rate law equation.
Use algebra to solve for the unknown, C(f).

STEP 1: Since the reaction is a second order reaction, the integrated rate law will be:

$\frac{1}{C_{f}} = \ kt \ + \frac{1}{C_{i}}$

where:

C(f) is the final concentration

k is the rate constant

t is the time

C(i) is the initial concentration

STEP 2: Plugging in the values given in the problem into the equation, the following equation should be obtained:

$\frac{1}{C_{f}} \ = (1.30 \ x \ 10^{-3} \frac{ \ 1 }{ \ M-s})(172 \ s) \ + \ \frac{1}{1.54 \ M} \\$

STEP 3: Using algebra to solve for C(f):

$\frac{1}{C_{f}} = \ 0.87295\\ \\C_{f} = \ 1.14554 \ M$

Since the given values only have 3 significant figures, the final answer must be expressed with 3 significant figures as well.

Therefore,

$\boxed {C_{f}\ = \ 1.15 \ M}$
