<u>Answer:</u> The final temperature will be 
<u>Explanation:</u>
Calculating the heat released or absorbed for the process:
In a system, the total amount of heat released is equal to the total amount of heat absorbed.
OR
......(1)
where,
C = heat capacity of water = 
= mass of water of sample 1 = 100.0 g
= mass of water of sample 2 = 71.0 g
= final temperature of the system = ?
= initial temperature of water of sample 1 = 
= initial temperature of the water of sample 2 = 
Putting values in equation 1, we get:
Hence, the final temperature will be
Answer:
<u></u>
Explanation:
<u>1. Balanced chemical equation</u>
- Ba(OH)₂(aq) + 2HNO₃(aq) → Ba(NO₃)₂(aq) + 2H₂O(l)
<u />
<u>2. Determine the number of moles of HNO₃ in the solution</u>
- n = M × V = 0.425M × 0.050 liter = 0.02125 mol HNO₃
<u>3. Use the mole ratio from the balanced chemical equation and the number of moles of HNO₃ to determine the number of moles of Ba(OH)₂.</u>
<u>4. Determine the molar concentration of the solution of Ba(OH)₂</u>
- M = 0.010625mol/0.0368liter
Periods go left to right or horizontally. Groups are a name for the vertical columns in a periodic table. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital.
