Answer:
There are two correct choices:
- Real gas particles have significant volume
- Real gas particles have more complex interactions than ideal gas particles.
Explanation:
Ideal gases are not real; ideal gases are a theoretical model used to confere a better understanding of gas properties. This model permits to predict the behavior of the gases using the ideal gas law, which is valid under certain conditions (mainly low pressure and high temperature).
Kinetic molecular theory states these basic assumptions for gases:
- Gas particles are in constant, random motion.
- Gas particles move in a straight line until they collide with another particle or the walls of the container.
- Gas particles are much smaller than the distance between particles, so most of the volume of a gas is therefore empty space, and the particles are considered to occupy no space.
- There is no force of attraction acting on gas particles nor between them
- Collisions are perfectly elastic, meaning that no energy is lost durign collisions.
Those conditions are not perfected matched by real gas particles, since real gas particles do occupy a volume and interact with each other, this is real gas particles have significant volume and have more complex interactions than ideal gas particles.
Answer
Option 1 - Real gases are always hotter than the ideal gases.
Explanation
Gases that are different from ideality are called real gases because they are always hotter than the ideal gases as they are flying past each other at an extremely high speed that creates kinetic energy. Whereas idea gases have absolutely elastic collisions, this is as it has a valuable theory because it embraces the perfect concept of original gas law.
Answer
Option 2 - Real gases particles have significant volume.
Explanation
Real gases have significant volume because they have a high temperature and have a higher volume as compared to ideal gases. There is a general gas theory that is composed of several randomly crossing point particles. Several gases, for example, nitrogen, oxygen, and hydrogen can be manipulated like ideal gases within a generous immunity of the idea gas.
Answer
Option 3 - Real gases particles are smaller than an ideal gas.
Explanation
Real gas particles are smaller than ideal gas particles since they have a volume and are made up of molecules or atoms that typically take up some space than the ideal atoms. The ideal gas pattern manages to break at moderate temperatures level or greater pressures point when intermolecular energies and molecular mass enhances to be significant.

The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. A limiting reagent is the reactant that is used up first in a reaction. Therefore, option A is correct.
What is a limiting reagent?
A reactant that is completely consumed at the end of a chemical reaction is known as the limiting reagent. Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained.
The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.
The terms limiting reagent and limiting agent may also be used to describe the limiting reactant.
Thus, option A is correct.

Answer:
The correct answer is C: A triglyceride
Explanation:
A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms. A carbohydrate is is a synonym of saccharide.
A triglyceride is an ester derived from glycerol and three fatty acids. So not a saccharide. The other 3 options all are saccharides. Triglycerides are the main constituents of body fat.
Final answer:
Triglyceride is not a type of carbohydrate molecule. It's a type of fat found in the blood, while disaccharides, glucose molecules and polysaccharides represent different types of carbohydrates.
Explanation:
Among the choices A. A disaccharide, B. A glucose molecule, C. A triglyceride, and D. A polysaccharide, option C. A triglyceride is NOT a type of carbohydrate molecule. Instead, triglycerides are a type of fat found in the blood. A person's body converts calories it doesn't need for energy into triglycerides. On the other hand, disaccharides, glucose molecules and polysaccharides are all different types of carbohydrates, which are molecules consisting of carbon, hydrogen, and oxygen atoms.

Step 1:
Epoxidation of Alkene:
In first step Cyclohexene is treated with peroxybenzoic acid in the presence of Dichloromethane which results in the formation of epoxide moiety.
Step 2:
Nucleophillic Substitution Reaction:
In second step the epoxide formed is treated with Sodium Methoxide which acts as a nucleophile and attacks the less hindered carbon of epoxide resulting in the formation of final product as shown below.
Final answer:
The best reagent and condition for a chemical reaction is dictated by the reactants at hand and the substance that you're trying to produce. For instance, to convert an alkene into an alcohol, Osmium Tetroxide (OsO4) at room temperature would be an example of an ideal reagent and condition.
Explanation:
In chemistry, when you are asked to place the best reagent and conditions in a reaction box, you are trying to predict the proper chemical, heat, or pressure conditions that will foster a certain chemical reaction. This requires understanding of substances' chemical properties, behavior under different conditions, and reaction mechanisms. For instance, if we want to oxidize an alkene into an alcohol, we would choose a reagent like Osmium Tetroxide (OsO4). In this case, OsO4 would be our 'best reagent', and room temperature may serve as the ideal condition as it generally facilitates this process. Each reagent and condition depend on the reactants you start with and the product you want at the end.

Answer:
B.
Explanation:
The electron dot diagram which is also known as the Lewis electron dot diagram is a diagram that shows an atom's valence electrons by placing dots, which represent the valence electrons of the element, around the elements symbol
The element for which the electron dot diagram is found = Neon, Ne
The atomic number of neon, Ne = 10
The electronic configuration of neon = 1s²2s²2p⁶
The valence shell is the outermost shell having the highest value of the coefficient of the orbitals, n = 2s²2p⁶
The number valence electrons in neon = The number of electrons in the valency shell = 2 electrons + 6 electrons = 8 electrons
The number of valence electrons in neon = 8
Therefore, the electron dot diagram for neon will have 8 dots located around the Ne symbol, which gives option B
