Answer:
C. polarity
Explanation:
Water is polar that is why it is a universal solvent.
Avodagros number i.e. 6.023 ×10^23
Explanation:
Many transition metals cannot lose enough electrons to attain a noble-gas electron configuration. In addition, the majority of transition metals are capable of adopting ions with different charges.
Answer:
Explanation:
From the given information;
Let Q(t) = mass of dye in the tank as a function of time
The mass in the tank = 200 L × (1g/L) = 200 g
Using the law of mass conservation;



Q(0) = 200
By finding the solution to the ODE using the method of separation of variables;


Using the initial condition;
200 = Q(0) = C

1% of 200g = 2g of dye solution
∴



t = 460.5 hours
