Both D and G options. Weak base and its conjugate acid or weak acid and its conjugate base are the possible components of a buffer solution.
Explanation:
Buffer solution is the solution which gets easily dissolved in water and so called as "Aqueous solution".
Buffer solution is essentially made up of two components Known as:
i.) Weak base and its conjugate acid
ii.) Weak acid and its conjugate base
This weak acid and base solution is used to maintain the pH value of the solution in a balanced way.
When the weak acid or base solution is added to strong acid or base solution that is the way pH gets balanced .
In one word buffer solution is the solution which resists for the pH change when strong acids or bases are added.
Answer:
magnesium+ hydrochloric acid is the reactants
Explanation:
the reactants are always in the left and the products are always in the right by
magnesium+hydrochloric acid ⇒ magnesium chloride + hydrogen
by combining magnesium and hydrochloric acid it produces magnesium chloride and hydrogen.
hope this helps..
4H202->2H2O+O2
Hope this helps mate good luck on whatever ur doing
Answer:
25,272
Explanation:
Multiply 9.0 x 108 = 972
Multiply 3.0 x 10 = 30 - 4 = 26
Lastly, multiply 972 x 26= 25,272
The ratio of mole number of the reactants and products is equal to the coefficients. So the answer is a. 18.75 mol. b. 35.1 g. c. 1.38 * 10^5 g.
