Answer:
Is called a diluted solution
Explanation:
Having little solute makes the dissolving process in a large amount of solvent very easy to mix therefore it dilutes in the solvent
Answer:
See explanation
Explanation:
1) Physical change is usually reversible, while chemical change isn't
2) Chemical change involves the change of chemical composition of matter while physical change doesn't
The reaction of iron sulfide (FeS) with hydrochloric acid (HCl) results in the formation of ferrous chloride (FeCl2) and hydrogen sulfide (H2S) gas. The reaction can be shown as follows:
FeS (s) + HCl(aq) ---- FeCl2(s) + H2S(g)
The bubbles indicate the formation of H2S gas which is a chemical change. The formation of bubbles indicates this change as it suggests that the reactants are combing to form products i.e. it signals a chemical reaction.
Answer:
100 ml = 0.1 L
I divided 100 by 1000 because 1000ml = 1L
Answer : The atoms in this compound are Copper(Cu), Chlorine(Cl), Hydrogen(H), Oxygen(O).
Explanation :
The given compound is copper chloride bi-hydrate which is also called as copper (II) chloride dihydrate as it contains two water of crystallisation.
The formula of copper chloride bi-hydrate is 
.
Therefore, there are 4 atoms in this compound and they are Copper(Cu), Chlorine(Cl), Hydrogen(H) and Oxygen(O).
