Answer:

A single element or many elements  

Step-by-step explanation:

A molecule consists of <em>two or more atoms</em> of the same or different elements that are bound together.

Examples of molecules are O₂, H₂O, CH₂O, and C₂H₃OCl.

C is <em>wrong</em>, because a molecule must contain at least two atoms.

Answer: Option (a) is the correct answer.

Explanation:

When two or more atoms are chemically combined together then the product formed is known as a molecule.

These atoms can be bonded through either covalent or ionic bonds.

For example, a water molecule consists of two hydrogen atoms combined with an oxygen atom. Chemical formula of water is H_{2}O.

Thus, we can conclude that an element can be made of many elements.

Which statement correctly describes the relationship between reactant and yield? The actual yield is calculated from the amount
melamori03 [73]
The statement which correctly describe the relationship between the reactants and the yield is this: 'the theoretical yield is calculated from the amount of the limiting reactants present'. The theoretical yields is the ideal maximum amount of a product that can be produced during a chemical reaction while the limiting reactant is the reactant that determines the maximum amount of product that can be formed.

As the volume of a 1 mole sample of gas increases, with the temperature remaining constant, the pressure exerted by the gas:
Vinvika [58]
I believe the correct answer would be decreases. At constant temperature, the volume and pressure are inversely related that is when one value increases the other decreases or as one decreases the other increases. Hope this helps. Have a nice day.
