Answer:
True
Explanation:
the relative amount of a given substance contained within a solution or in a particular volume of space; the amount of solute per unit volume of solution;.
Answer: Option (b) is the correct answer.
Explanation:
In solids, atoms are held together because of strong intermolecular forces of attraction between them.
As a result, solids have a definite shape and volume. Hence, its molecules are not able to slide past each other.
Whereas in liquids, molecules are together by less strong forces as compared to solids. Therefore, liquids do not have fixed shape and volume. They occupy the shape of a container in which they are kept together.
Therefore, molecules of a liquid are able to slide past each other.
In gases, molecules are held by weak Vander waal forces. So, they collide rapidly and occupy the volume of container and not the shape. Similarly, plasma is a hot ionized gas which consists of positive ions and negative electrons. Like gases, plasma also occupies the volume of a container.
Thus, we can conclude that liquid is the matter which can fill a container from top to bottom.
Hello, Lindaparker, a spit could form from a rocky headland where prevailing winds would
blow at an angle to the rocky headland, gradually depositing sand and
shingle at that place. A spit is a permanent land form resulting
from marine deposition and wind deposition. It is usually a long and
narrow accumulation of sand or shingle with one joined to the land and
the other end projecting at a narrow angle out into the sea. Salt marshes sometimes form on the sheltered side of a spit.
In a) the final equation is AgNO3 + KCl = AgCl + KNO3, b) Ni(NO3)2 + Na2S = 2NaNO3 + NiS; c) CaCl2 + Na2CO3 = 2 NaCl + CaCO3. In 2) The total net equation is Ca 2+ + CO32- = CaCO3 (s).
