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>
I think you forgot to include the picture so that we could easily identify the bond. No matter, I can introduce the types of bonds involved in chemistry. There are only two: the sigma bond (first picture) and the pi bond (second picture).
The sigma bond is formed when the two electrons sharing an orbital are overlapped head-on. In other words, they overlap each other entirely. While a pi bond is a side-to-side overlapping kind of sharing. That is why sigma bonds are much stronger than pi bonds.
In this case, just please refer to the picture for you to identify which type of bond is it indicated in your homework.
Hello!
Atomic Number, is the number where the atom lays on the perodic table and can be found through the number of protons. Meaning that gallium has an atomic number of 31 !
Atomic weight, which is equal to 70 in this case, can be found by subtracting the atomic number from that total to find the remaining number of neutrons that make up the mass. So gallium has 31 protons and 39 protons.
Hope this helps answer your question.
This is called a life span.
Explanation:
Jen runs at a little under 10m per second. Ann runs about 6m per second. Jen won because her time was faster. She reached 50m by 6 seconds while it took Ann 8 seconds. If the graph displayed their motion stopping, the line would continue straight horizontally along the 50m line as they would not be running anymore.
