Answer:
Higher pH (more alkaline)
Explanation:
The pH scale measures on a scale of 0 to 14 the acidity or basicness of whatever is being tested.
The lower the pH, the more acidic it will be. Acids are scaled as being anything having a pH of lower than 7.
The higher the pH, the more alkaline (or basic) it will be. Bases are scaled as being anything having a pH of higher than 7.
Substances that are at a pH of 7 are considered neutral, like water (H2O)
Answer:
If you put everything in the same column, then click done when there's two options, it'll put the ones that don't go into the column outside of the boxes and then you can out the remining ones into the other box. If you've already answered this once then it won't work and I'm really sorry for wasting your time. >.<
0.379 J · g⁻¹ · °C⁻¹.
<h3>Explanation</h3>
Energy change Q = c · m · ΔT.
Temperature change ΔT = Final Temperature - Initial Temperature.
The final temperature of both brass and water is 32.0 °C. However, the two differ in initial temperature.
Initial temperature
- Brass: 95.0 °C;
- Water: 25.0 °C.
How much energy did water gain in this process?
- Heat capacity c: 4.18 J · g⁻¹ · °C⁻¹;
- Mass of water m: 335 g;
- Temperature change ΔT: 32.0 - 25.0 = 7.0 °C.
.
How much energy did brass lose in this process?
The brass cylinder is cooled in a calorimeter. The calorimeter traps heat inside, such that water absorbs all the heat lost from the brass.
.
What's the heat capacity of brass?
- Heat capacity of brass is to be found;
- Mass of the cylinder: 410 g;
- Temperature change: 95.0 - 32.0 = 63.0 °C.
