Answer:
take the log of a given hydrogen ion concentration and reverse the sign.
Explanation:
To answer this question, we'll need the molar masses of nickel and vanadium:
Molar mass of nickel: 58.693g/mol
Molar mass of vanadium: 50.941g/mol
These values represent the mass of one mole of the element. A mole is the weight of Avogadro's number of atoms of an element (6.02 x 10^23 atoms).
We are given 58.693g of nickel, which is equivalent to one mole of nickel. Therefore, you will get the same number of atoms from one mole of vanadium, or 50.941g of vanadium.
Yes the correct answer is 3.14
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.
