When making a lewis structure of HCL, there are 3 lone pairs or pairs of electrons in that molecule
Answer:
Explanation:
Hello!
In this case, since the reaction between two aqueous solutions may turn out in the production of a solid precipitate, for potassium carbonate and calcium chloride, calcium carbonate is precipitated out as shown below:
Now, since the two reactants are in a 1:1 mole ratio, we infer they react in the same proportion, thus we compute the reacting moles, considering the used volumes of those molar solutions:
Thus, since just 0.00465 mol out of 0.00502 moles of calcium chloride are consumed, the potassium carbonate is the limiting reactant, therefore the mass of yielded calcium carbonate (molar mass = 100.09 g/mol) is:

A. Atoms make up molecules like letters make up words
Answer: The given statement is false .
Explanation:
Noble gases are least reactive elements in the periodic table. Noble gases have fully filled stable electronic configuration which the reason of their inert and lest reactive nature.
For example : Helium. Neon, argon etc.
Answer:
The answer to your question is: Al, Si have the greatest and S, C have the smallest.
Explanation:
Atomic radius increases from right to left in the periodic table.
Atomic radius increases from the upper section to the lower section of the periodic table.
Order of the atomic radius from highest to lowest.
Al, Si, S and C
