b) In gases molecular collisions transfer momentum between fluid.
Answer:
--Acid is the substance when dissolved in water, increases the concentration of H+ ions.
--Such compound whose chemical formula begins with H, for example HCl (Hydrochloric acid), H3BO3 (Boric acid), CH2O3 (Carbonic
acid). Although CH3COOH (Acetic acid) is an exception.
--Its less than 7.
--Bases are the proton acceptor.
--Such compounds whose chemical formula ends with OH, for example KOH (Potassium hydroxide), NaOH (Sodium hydroxide).
--Its greater than 7.
Explanation:
The condensation point of water is the same as its boiling point. This means that it is 100°C (212°F). Hope that helps!
.4 M means that in 1 Liter of solution there are .4 moles.
Molarity x Liters = Moles
We have molarity, so convert mL to liters
250 mL x 1000mL/1 Liter = .25 L
Now, set up the equation
.4 M x .25 L = .1 moles of solute
