Answer:
The answer is Zn(NO3)2 + 2NaOH => Zn(OH)2 + 2NaNO3.
Explanation:
Zinc is less reactive than Sodium so it will be displaced from NO3- and Sodium will replace Zinc's position.
Answer is:
Less than the vapor pressure of pure water
Answer:
52.1 degrees C
Explanation:
We need to use the equation: q = mCΔT, where m is the mass in grams, C is the specific heat capacity, and ΔT is the change in temperature.
Here, m = 10 g and q = 125 J. The heat capacity of iron is about 0.461 J/(g * C). And, our initial temperature is 25. So:
125 J = (10 g) * (0.461 J/(g * C)) * (T_f - 25)
Solving for T_f (final temp), we get: 52.1 degrees C
Hope this helps!
The two parts of a solution are a Solute and the other one is a Solvent. The Solute is the substance that dissolves, and the Solvent is the majority of the solution.
