Why earth not flat and why we live in this country not yours
bagirrra123 [75]

Answer:

Earth is not flat because the spheroidical shape provides a more effective shape in terms of exposed surface area for absorbing and radiating radiation, and also for a relatively more uniform gravity pull on different points on its surface which might not be so for a flat surface.

You live in your country, not mine because you have evolved over time to be more adapted to living in your own kind of envoirment. Members of a certain species (like you and me as humans) have been spread to maximize the survivability of their species compared to if they were clustered to a particular place.

A 1.200 liter solution contains 35.0 grams of potassium iodide (KI). What is the molarity of this
enot [183]

Answer:

M = 0.177

Explanation:

First, we have to find the molar mass of potassium iodine (KI).

K = 39.098

I = 126.904

Now, add these values together to get the molar mass of KI

39.098 + 126.904 = 166.0028

Now, it's time to do a grams to moles conversion.

35.0 g KI * \frac{1 mol KI}{166.0028 g KI} = \frac{35.0}{166.0028} = 0.212 mol KI

Now, we can find the molarity of this solution.

Molarity (M) = \frac{mol}{L}

M = \frac{0.212 mol KI}{1.200 L} = 0.177 M

The molarity (M) of this solution is 0.177.

Jimmy developed a model to show the difference between pure substances and mixtures
IrinaK [193]
  1. Pure substances cannot be separated into any other kinds of matter, while a mixture is a combination of two or more pure substances.
  2. A pure substance has constant physical and chemical properties, while mixtures have varying physical and chemical properties.

<u>Explanation:</u>

  • A matter which cannot be separated into any other kind of matter using the chemical or physical process is called pure substances. A pure substance has the same color, composition, and texture.
  • An element consisting of a single compound with a definite composition, physical and chemical properties are called pure substances.
  • A combination that has as of many substances that are not united using a chemical procedure or any process is known as mixtures. A mixture does not exist in fixed proportions, and most of the natural substances are mixtures.
