I would say that descriptive investigations aren't repeatable because it means that you are only describing something - you ask certain question about something, but do not form a hypothesis at that point yet. So it would be a waste of time to simply ask the same questions over and over again with no hypothesis to prove, which is why these types of investigations cannot be repeated.
The equation of the reaction is;
Ca(OH)2(aq) + 2HCl(aq) ------> CaCl2(aq) + 2H2O(l)
<h3>What is neutralization?</h3>
The term neutralization has to do with the process in which an acid reacts with a base to form salt and water only. A neutralization reaction is known by the fact that water is obtained by the reaction of hydrogen and hydroxide ions.

Answer:
Lewis structures, also known as Lewis dot diagrams, Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. A Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds
Explanation:
Answer:
3.25 mol CO₂
Explanation:
Step 1: Write the balanced equation
C(s) + O₂(g) ⇒ CO₂(g)
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of O₂ to CO₂ is 1:1.
Step 3: Calculate the number of moles of CO₂ produced from 3.25 moles of O₂
We will use the previously established molar ratio.
3.25 mol O₂ × 1 mol CO₂/ 1 mol O₂ = 3.25 mol CO₂
