A molecule can be made of which of the following? many elements a single element a single atom
2 answers:
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
Thus, we can conclude that an element can be made of many elements.

Answer:
150.0 mL.
Explanation:
It is known that the no. of millimoles of HNO₃ before dilution = the no. of millimoles of HNO₃ after dilution. ∵ (MV) before dilution = (MV) after dilution.
<em>∴ V before dilution = (MV) after dilution / M before dilution </em> = (0.15 M)(500.0 mL)/(0.50 M) = <em>150.0 mL. </em>
The concentration of [CI-] : 0.617 M

Answer: You can use Boyle's law, which states that pressure is inversely related to volume when other variables are held constant. If the final pressure of a gas is half of the initial, the volume must double if temperature is to remain the same.
