The density of water is about 1.00 g/ml, so 500 ml of water is about 500 g
The correct answer is: [C]: "polar" .
_____________________________________________________
" Water " ; which is: " H₂O " ;

is a:

— polar; → {eliminate: "Choice [A]: "non-polar"} ;
→ {and consider: "Choice: [C]: "polar" } ;
— covalent; → {not "ionic"; eliminate: "Choice: [B]: "ionic"} ;
— uncharged; → {neutral compound; not "charged" —but "balanced"} ;
→ {Note: " H ⁺ , O ²⁻ ; → " H₂O " } ;
→ The "charges" balance/ cancel out.
→ {eliminate: "Choice: [D]: "charged" .}.

Answer:
The degree of compactness of a substance
Answer:
1 and 3 only
Explanation:
When a reaction is equilibrium, its forward reaction and reverse reaction are happening at the same rate. For a reaction to have a forward reaction and reverse reaction, the reaction must be reversible. Therefore, statement #2 is incorrect. Now, since the forward reaction and reverse reaction are moving at the same rate, the rate at which products are being converted to reactants is equal to the rate at which reactants are being converted to products. This means the concentrations of the reactants and products stay constant. That means statement #3 is correct. For equilibrium to happen, the system must be closed though. If a system is closed, that means no hydrogen, iodine, or hydrogen iodide can escape the system. Therefore, statement #1 is also incorrect.
