Answer:
<h2>2.57 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question we have
volume = final volume of water - initial volume of water
volume = 22.76 mL - 15.35 ml = 7.41 mL
We have the final answer as
<h3>2.57 g/mL</h3>

Answer:
Oxidation occurs at the anode: Fe(s) | Fe2+(aq) half cell. (ii) Reduction occurs at the cathode: Ag(s) | Ag+(aq) half cell. Oxidation occurs at the anode: Pt | Sn2+(aq), Sn4+(aq) half cell. (iii) Electrons flow from the anode to the cathode: from the Pt(s) → Ag(s) electrode.
Answer: Ionic formula will be .
Explanation: and ions will form a ionic compound. Ionic compounds have both metals and non-metals.
Here is a metal and is a non-metal.
The net charge on any compound must be 0.
So we need 2 phosphate ions to balance the charge on ions. Similarly we need 3 Magnesium ions to balance the charge on ions.
Criss-crossing the charges, we will get the formula as
Criss-crossing is shown in the image below.
The Antoine's law means that the amount of substance before reaction must be equal the amount of substance after reaction
The equation h2 + cl2 ---> 2hcl correctly models this law.
