Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms ,and because the carbon atom is just the right ,small size to fit in comfortably as parts of a very large molecules.
Given what we know about lab safety, we can confirm that when dealing with unstable and erratic equipment such as the stirring mechanism, in this case, the best course of action is to deactivate the equipment until further notice.
<h3>Why should we turn off the equipment?</h3>
- The erratic nature of the stirring mechanism is making the entire system unstable.
- When dealing with a hot plate, and heating substances, we need to maintain stability at all times.
- We do this to avoid spills that may cause burns or other unwanted damages.
- Therefore, until we know why the stirring was erratic, we must turn the mechanism off.
Therefore, we can confirm that when dealing with faulty or unstable lab equipment, we must deactivate the equipment immediately in order to preserve our lab safety.

Answer: a mathematical expression describing the probability of finding an electron at various locations; usually represented by the region of space around the nucleus where there is a high probability of finding an electron
Explanation:
Answer:
7.5 L of the 10% and 22.5 L of the 30% acid solution, she should mix.
Explanation:
Let the volume of 10% acid solution used to make the mixture = x L
So, the volume of 30% acid solution used to make the mixture = y L
Total volume of the mixture = <u>x + y = 30 L .................. (1)
</u>
For 10% acid solution:
C₁ = 10% , V₁ = x L
For 30% acid solution :
C₂ = 30% , V₂ = y L
For the resultant solution of sulfuric acid:
C₃ = 25% , V₃ = 30 L
Using
C₁V₁ + C₂V₂ = C₃V₃
10×x + 30×y = 25×30
So,
<u>x + 3y = 75 .................. (2)
</u>
Solving 1 and 2 we get,
<u>x = 7.5 L
</u>
<u>y = 22.5 L</u>
