Answer:

19.278049929737628457607385688801

Explanation:

Volume = L * W * H

Volume = 17.78 * 9.21 * 4.45 = 728.70441

Density = Mass / Volume

Mass = 14,048

14,048 / 728.70441 = 19.278049929737628457607385688801

Density = 19.278049929737628457607385688801

Explanation:

So density = mass/volume

Using this formula we'll solve the question.

mass = 14,048g/1000 = 14.048 kg

volume = 17.78/100 x 9.21/100 x 4.45/100

volume = 0.3143 m³

density = 14.048 kg/ 0.3143 m³

density = 44.69 kg/m³

round off to = 44.7 kg/m³

Write differences between homogeneous mixture and heterogeneous mixture​
Pie

Answer:

Homo means same

Hetero means different.

Homogeneous mixtures have one phase, it all looks the same, Fruit juice is homogeneous, solutions are homogeneous.

Heterogeneous mixtures have different phases, you can see the different parts, pepper is an example of a heterogeneous mixture.

  • A homogeneous mixture - Think Kool Aid (Completely Dissolved)
  • A heterogeneous mixture - Like pepper poured into a glass of milk.

In a homogeneous mixture the constituents are able to dissolve in each other due to their similar intermolecular forces, whereas in a heterogeneous mixture the constituents are not miscible- meaning they can't dissolve in each other.

To clarify: intermolecular forces describe the way that types of molecules will interact with each other. For instance, water (a polar molecule) and naphthalene (a non-polar molecule) are said to be "immiscible" because their intermolecular forces do not match. The saying goes: "like dissolves like". Meaning that molecules that have similar IFs will be mutually soluble (miscible, in other words).

  • Homogenous means the same all over...every cubic millimeter is about the same as every other one. Like water or soda.
  • Heterogenous means difference in places, like salsa, with slightly different chunks of stuff depending on where you dipped your chip.

Caclulate the pH of a solution with a hydrogen ion concentration of 1X10-7
LUCKY_DIMON [66]

Answer:

The pH of the solution is 7.00 .

Explanation:

The pH gives us an idea of the acidity or basicity of a solution. More precisely, it indicates the concentration of H30 + ions present in said solution. The pH scale ranges from 0 to 14: from 0 to 7 corresponds to acid solutions, 7 neutral solutions and between 7 and 14 basic solutions. It is calculated as:

pH = -log (H30 +)

pH= -log (1x10^-7)

<em>pH= 7.00</em>
