Answer:
0.18 L
Explanation:
You can find the volume using the molarity ratio:
Molarity = moles / volume (L)
You can plug the given values into the equation and simplify to find the volume.
Molarity = moles / volume <----- Molarity ratio
2.5 M = 0.45 moles / volume <----- Insert values
(2.5 M) x volume = 0.45 moles <----- Multiply both sides by volume
volume = 0.18 L <----- Divide both sides by 2.5
Answer: Mass is the amount of matter in a substance. Volume is the amount of space matter takes up. Matter has both physical and chemical properties.

<u>Answer: </u>The correct answer is Option A.
<u>Explanation:</u>
The molecule given in the question is HCl which forms a polar covalent bond.
A polar bond is defined as the bond present between two elements with different electronegativity value. The element which has higher electronegativity value, attracts the shared pair of electrons towards itself and forms a dipole. A polar molecule is dissolved more in a polar substance than in non-polar substance.
In the given compound, the electronegativity of chlorine is more than hydrogen and attracts the shared pair of electron more towards itself and hence is a polar molecule.
A non-polar bond is defined as the bond which is formed between the elements having same electronegativity value. No dipole is created in these type of bonds. Here, the electrons are shared equally.
From the above information, the correct answer is Option A.
Answer:
This bag has been made from introduced materials, but before foreign fibres were used dilly bags were made from bark, leaves, stems, roots, human hair, animal fur and animal sinew.
