Answer:
OH⁻
Explanation:
A base is defined as a substance which interacts with water to yield excess hydroxide ions, OH⁻, in an aqeous solution.
Examples are Sodium hydroxide (NaOH)
Potassium hydroxide (KOH)
Bases are generally certain metallic oxides, metallic hydroxides and aqueous ammonia.
An acid is a proton donor, H⁺ and it interacts with water to produce excess hydroxonium ions in an aqueous solution.
Answer:
The speed of a wave is a measure of the product of its frequency and wavelength. ... Since the frequency is kept constant, then it is the constant of proportionality. The wavelength is directly proportional to the speed. Therefore, if speed is increased, wavelength will increase.
Answer:
THE MOLARITY OF THE SOLUTION IS 0.1039 MOL/DM3
Explanation:
Molarity is the number of moles of solute in a given solution,
Molarity in mol / dm3 = Molarity in g/dm3 / Molar mass
Mass = 15.2 g
Volume of solution = 2.5 l
Molar mass of NaCl = (23 + 35.5) = 58.5 g/mol
First, we calculate the molarity in g/dm3
Molarity in g/dm3 = mass /volume
= 15.2 g * 1 L / 2.5 L
=6.08 g /dm3
Hence, we will introduce the values and solve for molarity in mol/dm3
Molarity = 6.08 g/dm3/ 58.5 g/mol
Molarity = 0.1039 mol/dm3
The molarity of the solution is 0.1039 mol/dm3
