Answer:
4) Titration
Explanation:
Titration is a common process used to determine the concentration of acids. It does this by adding a solution of base with a known concentration to the acid until it reaches neutralization.

Explanation:
Answer:
96 m/s.
Explanation:
Distance equals speed x time,
12 x 8, so the distance is 96 m/s.
Answer: kinetic energy
Explanation: searched it up
Answer:
26.5 g
Explanation:
First we convert 100.0 mL to L:
- 100.0 mL / 1000 = 0.100 L
Now we <u>calculate how many moles of sodium carbonate are needed</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- moles = molarity * liters
- 2.5 M * 0.100 L = 0.25 mol
Finally we <u>convert 0.25 moles of sodium carbonate into grams</u>, using its <em>molar mass</em>:
- 0.25 mol * 106 g/mol = 26.5 g
