(3) <span>electronegativities of the bonded atoms in a molecule of the compound is the correct answer.
The compound is nonpolar when</span> electronegativity is from 0 to 0.5, polar when electronegativity is from 0.5 to 1.7, and ionic when electronegativity is larger than 1.7.
Hope this would help~
First, let's find the number of neutrons in Calcium-40. to find the number of neutrons, you need to take the atomic mass minus atomic number
neutrons in Calcium---> 40 - 20 (atomic number) = 20 neutrons
potassium-40---> 40- 19= 21
scandium-44----> 44- 21= 23
argon-38---------> 38- 18= 20
chlorine-36------> 36- 17= 19
the answer is argon-38
2H2 + O2 -> 2H2O.

Answer:
Here's what I get
Explanation:
Inherited traits are traits that you received from your parents at birth.
Acquired traits are traits acquired during your lifetime, like knowing how to ride a bicycle. You cannot pass them down to the next generation.
Only your inherited traits will enable you to survive predators, find enough food to live, etc. If you must learn a skill to survive, you probably won't live long enough to pass your genetic information to your offspring.
Without conducting an experiment, one can determine if a species in a solution is acidic or basic by using a litmus paper.
<h3>Litmus test</h3>
Acidic species would turn a blue litmus paper to red but have no effects on red litmus paper.
Basic species would turn a red litmus paper to blues but have no effects on blue litmus paper.
Thus, in order to determine if a species in a solution is acidic or basic without conducting any experiment, dipping a litmus paper into the solution would give an indication.
