Answer:
speed=5cm/minute
Explanation:
Given at 2:00PM the hermit is at 10cm mark
Also given that the hermit reaches 60cm mark at 2:10PM
Therefore the time elapsed is 10 minutes = 
the distance travelled by the hermit is 60-10=50cm=0.5m
We know that


speed =
m/sec=5cm/minute
Activity series of metals: K,Na,Mg,Al,Zn,Fe,Cu,Ag. Metals on the left are more reactive than metals on the right. For example Zn is more reactive than Fe and can displace him.
Reaction than can occur is: <span>CuSO4(aq) + Fe(s) → FeSO4(aq) + Cu(s).</span>
Answer is: Kp = 66,586.
Chemical reaction: PCl₃(g) + Cl₂(g) ⇔ PCl₅(g).
Kp - equilibrium constants expressed in terms of partial pressures of gases.
Kp = p(PCl₅) ÷ p(PCl₃) · p(Cl₂). p-partial pressure.
Kp = 1,67 atm ÷ 0,132 atm · 0,190 atm
Kp = 66, 586 1/atm. Favors product.
57.167days will be required for 4.68g to remain
For an aqueous solution to conduct electricity, ions must be
present in solution.
This means soluble salts will conduct electricity. Also,
since acids and bases have ions in solution, they could also conduct electricity.
Option 1 is a soluble salt. Options 2 and 4 are base and acid respectively.
Option 3, though soluble in water, exist as a molecule, therefore its solution
cannot conduct electricity.
