Answer:
Double replacement reaction
Explanation:
Now, let us first write the reaction equation properly:
H₂SO₄ + 2KOH ⇒ K₂SO₄ + 2H₂O
The above reaction is a neutralization reaction between an acid and a base whose product gives salt and water only at most instances.
From here, we can observe that the species displaces on another in their ionic state. Hydrogen replaces potassium and water is produced. Potassium combines chemically with sulfate ions to give the salt of potassium.

Answer:
a. 0.191 ppm b. 4.962 ppm c. 0.0385 ppm
Explanation:
a. 17 g of calcium = 0.017 mg. 89 mL = 0.089 L.
So our concentration = 0.017 mg/0.089 L = 0.191 mg/L = 0.191 ppm
b. 0.65 mg of caffeine in 131 mL = 0.131 L.
So our concentration = 0.65 mg/0.131 L = 4.962 mg/L = 4.962 ppm
c. 0.35 mg of trace particle in 91 dL = 9.1 L.
So our concentration = 0.35 mg/9.1 L = 0.0385 mg/L = 0.0385 ppm
Answer:
"3.90M" if approximate
Explanation:
if u didn't understood why i converted volume from millilitres to litre then refer defination of Molarity.
hope it help:)
