The ions in a formed;

  • 13 - Al - Al^3+
  • 34 - Se - Se^2-
  • 56 - Ba - Ba^2+
  • 7 - N - N^3-
  • 87 - Fr - Fr^+
  • 35 - Br - Br^-

<h3>What is the atomic number?</h3>

The atomic number is the number of protons in an atom. It is also the number electrons in the neutral atom. Now we know that when an ion is formed, electrons are lost or gained by the atom.

Let us now write the ions that are formed by each of the atoms of elements that have the atomic number as listed;

  • 13 - Al - Al^3+
  • 34 - Se - Se^2-
  • 56 - Ba - Ba^2+
  • 7 - N - N^3-
  • 87 - Fr - Fr^+
  • 35 - Br - Br^-

lara [203]

Answer:

No

Explanation:

The solubility of a solid in water refers to the amount of that solid that dissolves in water.

It is not possible to calculate the solubility of the solid because the student threw away the first precipitate that formed. We already have the volume of water, but having lost some mass of precipitate, it has become impossible to accurately determine the solubility.

Hence the answer provided above.

How did the nucleus evolve through time?
Tems11 [23]

Answer:

The nucleus represents a major evolutionary transition. As a consequence of separating translation from transcription many new functions arose, which likely contributed to the remarkable success of eukaryotic cells. Here we will consider what has recently emerged on the evolutionary histories of several key aspects of nuclear biology; the nuclear pore complex, the lamina, centrosomes and evidence for prokaryotic origins of relevant players.

Perform the following conversions:
spayn [35]

0 K in Celsius scale is -273 degree Celsius and in Fahrenheit scale 459 degree F.

The degree of a body's heat or cold is referred to as the gas's temperature. It is stated in temperature units such as, degree Celsius, Fahrenheit  and Kelvin these temperature units are interchangeable. To convert Celsius to Fahrenheit ° F = 9/5 ( ° C) + 32, kelvin to Fahrenheit= ° F = 9/5 (K - 273) + 32, Celsius to kelvin K = ° C + 273.  to convert Fahrenheit to Celsius ° C = 5/9 (° F - 32)  In this question,  to convert Fahrenheit to Celsius ° C = 5/9 (° F - 32) = 0-273 K (5/9 - F-32) =459 degree F. and kelvin to Celsius K - 273 = C = -273 degree Celsius

At 8^0C K= 8 + 273 =281 degree Celsius and at 8F , 8= 9/5(k-273) +32 =453 F
