For the given chemical reaction, there will be no shift in the equilibrium due to addition of a catalyst.
<h3>Equilibrium shift</h3>
Catalyst is a substance that speeds up the rate of chemical reaction. The presence of catalyst in a chemical reaction do not affect the shift.
Hence for the given chemical reaction, there will be no shift in the equilibrium due to addition of a catalyst.

The best way to make an accurate measurement of the height of a polar liquid is to take the reading from the lowest point of the meniscus.
<h3>What is the meniscus of a liquid?</h3>
The meniscus of a liquid is a curved that occurs at the top of a liquid placed in a container as a result of the attractive forces between the molecules of a the liquid.
Polar substances such as water have a concave meniscus as they dip downwards.
Therefore, the best way to make an accurate measurement of the height of a polar liquid is to take the reading from the lowest point of the meniscus.

Answer:
Grams (Metric Base Units)
Cant see the full question
But I hope this helps
Explanation:
5F2 + 2NH3 --> N2F4 + 6HF
<span>60.1g NH3 / 17g/mole = 3.54moles NH3 </span>
<span>3.54moles NH3 x (5 F2 / 2NH3) x 38g/mole = 335.85g required </span>
<span>5.25g HF / 20g/mole = 0.262moles HF </span>
<span>0.262moles HF x (2NH3 / 6HF) x 17g/mole = 1.49g required </span>
<span>209g / 38g/mole = 5.5moles F2 </span>
<span>5.5moles F2 (1 N2F4 / 5F2) x 66g/mole = 72.6g produced </span>
<span>Li3N + 3H2O --> NH3 + 3LiOH </span>
<span>(37.7g / 34.7g/mole) x (3H2O / 1 Li3N) x 18g/mole = 58.67g required </span>
<span>1.08moles Li3N (1NH3 / 1Li3N) x 6.022x10^23molecules/mole = 6.54x10^23 molecules </span>
<span>10.3L at STP: 10.3L / 22.4L/mole = 0.46moles NH3 produced </span>
<span>0.46moles NH3 x (1Li3N / 1NH3) x 34.7g/mole = 15.96g</span>
