Answer:
12 to 14
Explanation:
drain cleaners contain sodium hydroxide or potassium hydroxide which are strong bases . The pH value of sodium hydroxide and potassium hydroxide is 14 and 12 respectively on the pH scale. So, most drain cleaners have a pH of from 12 to 14, regardless of how much L there are.

Answer:
The formation of AN OXIDE
Explanation:
A combustion reaction is a chemical reaction which involves the burning of an hydrocarbon in oxygen
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the% m / m concentration of that solution is 6.66%.
