If bubbles aren't a for sure way of knowing a chemical reaction I don't know what is. But being for real, it is a chemical change because the bubbles are releasing carbon dioxide meaning it turned into a product from a reaction with outside forces.
Answer:
A) 15.5 mL
Explanation:
Given, Mass of oxalic acid = 0.3500 g
Molar mass of oxalic acid = 90.03 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the given reaction:
5 moles of oxalic acid react with 2 moles of potassium permanganate
Thus,
1 mole of oxalic acid react with 2/5 moles of potassium permanganate
0.0038876 mole of oxalic acid react with moles of potassium permanganate
Moles of potassium permanganate = 0.001555 moles
Also, considering:
Molarity = 0.100 M
So,
Volume = 0.01555 L
Also, 1 L = 1000 mL
So, volume = 15.5 mL
Answer:
The pH of 0.001 M HNO3 is pH 2.0
Answer:
It should be 115.5 amu but you didnt type that as an answer choice so...
Explanation:
Bruh all you had to do was add oxygen and sulfur and subtract from the total to get your answer :D.
