Mixtures

Explanation:

The forms of matter that exists without having chemical bonds between them are mixtures.

Mixtures are impure substances. They are made of matter that are not chemically bonded to one another.

Here are some of the characteristics of a mixture:

Composition is indefinite i.e they consist of two or more elements and or compounds in any proportion by mass
The constituents retain their identities i.e physical properties are not altered.
The constituents reacts differently to changed conditions.
They can easily be separated into constituents by physical methods.

Many natural mixtures exists and several others can be formulated. Examples include air, sea-water, muddy water, alloys e.t.c

Calculate the concentration of h3o⁺ in a solution that contains 5.5 × 10-5 m oh⁻ at 25°c. Identify the solution as acidic

Andreas93 [3]

Answer: $[H_3O^+]=1.6\times 10^{-10}M$ , the solution is basic

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.Neutral substances have pH of 7.

$pH=-\log [H_3O^+]$

$pOH=-\log[OH^-]$

Putting in the values:

$pOH=-\log[5.5\times 10^{-5}]$

$pOH=4.2$

$pH+pOH=14$

$pH=(14-pOH)=(14-4.2)=9.8$

$9.8=-\log [H_3O^+]$

$[H_3O^+]=1.6\times 10^{-10}M$

As pH is more than 7, the solution is basic

What is the density of 1.00 mol of carbon monoxide gas at STP?

Ksju [112]

Answer:

Density = mass / volume.

If this is an ideal gas then 1mol will take up 22.4L of volume (fact about ideal gases you should remember)

Since you have 1mol then you know the volume of the gas that you have (22.4L)

Now, just convert 1mol of CO to grams.The ptable tells you that the mass of 1 mol of C is 12g and the mass of 1 mol of O is 16g. So the mass of 1 mol of CO is......... :):)

Now you have the mass and the volume, so just divide :) enjoy
