Answer:

³⁸₂₀Ca.

Explanation:

³⁸₁₉K –> __ + ⁰₋₁β

Let ʸₓA represent the unknown.

Thus the equation above can be written as:

³⁸₁₉K –> ʸₓA + ⁰₋₁β

Thus, we can obtain the value of y an x as follow:

38 = y + 0

y = 38

19 = x + (–1)

19 = x – 1

Collect like terms

19 + 1 = x

x = 20

Thus,

ʸₓA => ³⁸₂₀A => ³⁸₂₀Ca

Therefore, the equation is:

³⁸₁₉K –> ³⁸₂₀Ca + ⁰₋₁β

Answer:

Kindly check explanation.

Explanation:

So, without mincing words the solution to this particular Question is given below:

First, an ELEMENT is a that entity that has what is known as the atoms. Although, there might be more elements but the recognized elements are group into the periodic table/chart. Examples of elements are Hydrogen, Helium, Lithium, Beryllium, Boron, carbon, Nitrogen, oxygen, Fluorine, neon, sodium, magnesium, Aluminium and so on.

A COMPOUND consist of different elements that are chemically combined. Examples of compounds are; H2O, CaCO3, H2SO4, HNO3, MgCl2, NaCl, HCl and many more.

Also, elements has the same atoms while componds have different number of atoms since it is a combination of elements.

Finally, ELEMENTS can not be broken down through the use of chemical process while COMPONDS can be broken down through chemical processes.

To the second part of the question. The box that will represent elements will contain balls of the same colors and the balls are not joined together.

What is a low pressure system?
KonstantinChe [14]

A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

<u>Explanation</u>:

  • Wind flow towards the low pressure and the air rises in the atmosphere. As the air increases, the water vapor within it solidifies, forming clouds and undergo precipitation. Low pressure formed in the center areas.
  • The atmospheric circulations of air up and down in a low-pressure area remove a small amount of atmosphere. This usually happens between warm and cold air masses by flowing air which tries to reduce the contrast of temperature.
