A/a physical change is when an object goes through a natural change such as weather etc.
B/ the different is that 1) chemical change is more quick to change rather than physical (ex: I’d there is rocks flying around and is wearing down another rock it would take longer rather than acid)
Answer:
[NaOH] = 0.1 Molar ... Note => the brackets around formula;i.e., "[ ]" is generally accepted in the chemistry community as concentration in Molar terms.
Explanation:
The metathesis rxn, or double replacement rxn, equation is:
(Molarity x Volume) of acid = (Molarity x Volume) of base, or
(M·V)acid = (M·V)base => M(base) = M·V(acid)/V(base)
= 0.1M × 18.3ml / 20ml = 0.0915M(base) = 0.1M (1 sig-fig) = [NaOH]

Answer:
Cytoplasm
Explanation:
Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm.
