Answer:
Take the measuring cylinder and measure its mass, in grams, as accurately as possible.
Take the measuring cylinder off the balance and add the water carefully. Put the measuring cylinder back on the balance. Measure and record the new mass .
Repeat the procedure, recording the volume and total mass, until the measuring cylinder is full. Then, for each volume calculate the mass of the liquid alone.Repeat steps 1 to 3 Draw a graph of mass of liquid against volume . Calculate the density of each liquid from the gradient of its graph line.

Answer:
- <u><em>The leftover reactant is the nitrogen gas, N₂.</em></u>
Explanation:
As per your description:
<u>1. Square on the left: N₂(g)</u>
- 3 units of two joint circles: this represents 3 molecules of nitrogen gas, N₂(g).
<u>2. Square on the right: H₂(g)</u>
- 3 units of two joint circles: this represents 3 molecules of hydrogen gas, H₂(g).
<u>3. Reaction</u>
If the maximum possible amount of NH₃ is formed during the reaction, you assume that the reaction goes to completion.
The chemical equation that represents the reaction is:
Which must be balanced:
That means that 1 molecule (or 1 mol) of N₂(g) reacts with 3 molecules (or 3 moles ) of H₂(g) to produce 2 molecules (or 2 moles) of NH₃(g).
Since, the squares show that there are 3 molecules of each reactant, the 3 molecules of hydrogen gas will be able to react with 1 molecule of nitrogen gas. When that happens, all the hydrogen gas is consumend and yet two molecules of nitrogen gas will remain unreacted. Hence, the nitrogen gas is the leftover reactant.
I think it’s carbon but I’m not sure
The middle element in a specific group of similar elements act as an intermediate between the other two because it is close to the average of the other two elements and is denoted as option C.
<h3>What is an Element?</h3>
These are the substances which aren't unable to be broken down by a chemical reaction and comprises of subatomic particles such as electron, proton etc.
The middle element in a specific group of similar elements act as an intermediate between the other two because it is close to the average of the other two elements when arranging the elements in order of their atomic masses.
