The temperature change on a 150g sample of mercury with specific heat of 0.0330 Cag°C, If 480 cal of heat is added to it is 96.9°C.
<h3>How to calculate temperature change?</h3>
The temperature change of a substance can be calculated using the following formula:
Q = m × c × ∆T
Where;
- Q = quantity of heat absorbed or released
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
480 = 150 × 0.033 × ∆T
480 = 4.95∆T
∆T = 96.9°C.
Therefore, the temperature change on a 150g sample of mercury with specific heat of 0.0330 Cag°C, If 480 cal of heat is added to it is 96.9°C.

an acid is an ionic compound that produces positive hydrogen ions when dissolved in water and a bacis is an ionic compound that produces negative hydroxide ions when dissolved in water
Well if it loses one electron, then you would have more protons, so I would assume you would have a positive charge :)
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
