Atoms must have equal numbers of protons and electrons. So to answer your question, yes protons and electrons are the same number.
Answer:
0.26g of NaCl is the maximum mass that could be produced
Explanation:
Based on the reaction:
HCl + NaOH → NaCl + H₂O
<em>Where 1 mol of HCl reacts per mol of NaOH to produce 1 mol of NaCl</em>
<em />
To solve this question we need to find <em>limiting reactant. </em>The moles of limiting reactant = Moles of NaCl produced:
<em>Moles HCl -Molar mass: 36.46g/mol-:</em>
0.365g HCl * (1mol / 36.46g) = 0.010 moles HCl
<em>Moles NaOH -Molar mass: 40g/mol-:</em>
0.18g NaOH * (1mol / 40g) = 0.0045 moles NaOH
As the reaction is 1:1 and moles NaOH < moles HCl, limiting reactant is NaOH and maximum moles produced of NaCl are 0.0045 moles.
The mass of NaCl is:
<em>Mass NaCl -Molar mass: 58.44g/mol-:</em>
0.0045 moles * (58.44g/mol) =
<h3>0.26g of NaCl is the maximum mass that could be produced</h3>
You would expect to find more Hydrogen ions ( H+) when an acid dissolves in water that is because the acid added to the water increases the concentration of ( H+ ) ions. Acid dissolving in water also decreases the pH level. As to when the acid dissolves it brakes down into H+ molecules and OH- molecules.
Gravity force is at least partially responsible for changing the energy of an object pushed off an edge.
Explanation:
- Gravity or gravitation, it is a phenomenon by the things with mass or energy including stars, galaxies, planets, and even light are taken to one another.
- The gravitational pull of the Universe's initial gaseous matter caused it to begin to coalesce and form stars, which caused the stars to gather together into galaxies, and gravity is responsible for all of the Universe's large-scale structures.
- Gravity has an unlimited range, but its effects are becoming ever weaker as items get away further.
