The statement above is FALSE.
Unlabeled atom joined to carbon atoms which are not directly part of a ring structure are assumed to be CARBON ATOMS. In a ring structure, an unlabeled atom at the angle where two lines joined together is always assumed to be a carbon atom<span />
The number of moles of A4B3 produced in a reaction is obtained by stoichiometry.
The term stoichiometry refers to mass-mole relationship. The first step in solving this problem is by writing the correct reaction equation as follows;
4A + 3B -------> A4B3
If 4 moles of A yields 1 mole of A4B3
10 moles of A yields 10 * 1/4 = 2.5 moles of A4B3
Therefore, 2.5 moles of A4B3 is produced.

Answer:
an increasng atomic number/ increasing proton count
Explanation:
The process involving separation of liquid/solid mixture as regards this question is Decantation.
- Decantation can be regarded as one of the process used in separation of liquid from solid as well as other immiscible (non-mixing) liquids through the removal of the liquid layer that is present at the top from the layer of solid/liquid which present at the below.
- In the process, the liquid will be poured slowly into another vessel as the pouring continues, then the solid will settle in the original vessel.
- This process can be done through tilting the mixture after the the top layer have been poured out.
<em>Therefore, decantation is one of the separation technique.</em>

<span>STP signifies standard temperature and pressure.
This conditions are at 1 atmospheric pressure and 0 degrees Celsius. It has
been said that at these conditions, one mole of a gas molecule is equivalent to
22.4 liters of volume. Therefore, the correct answer is the second option which
is 2 L of CH4.</span>
