If the pH of the acid at a given time is found to be 1.25, then the molarity of the gastric acid juice is 0.056M.
<h3>What is pH?</h3>
pH is define as the negative logarithm of the concentration of H⁺ ions present in any solution and it will be represented as:
pH = -log[H⁺]
Concentration will be present in the form of molarity and pH value for gastric acid is given 1.25 means it is strong acid as it completely dissociates into their ions.
Required equation for calculation will be:
[H⁺] =
[H⁺] =
[H⁺] = 0.056 M
Hence molarity of the gastric acid juice is 0.056M.

Answer: C.
Explanation: Your mass can't change due to the law of energy conservation, but your weight would be less because of the lack of gravity on mars
Explanation:
Spectator ions refers to elements/molecules that do not form part of the reaction. Basically, these elements/molecules are in the same state in the reactant and product side. From the given reaction, Ca and SO4 change their state from aqueous to solid and Na and Cl do not change their state. Therefore, Na and Cl are spectator ions and Ca and SO4 are not spectator ions.
Answer:
The correct option is C.
Answer:
sometimes google goes wrong
now it is showing potassium is more reactive but actually it is Not sodium is more like salts have less sodium bcz it is harmful so thats why sodium is stored in kerosene like if u inhale sodium your nose will bleed it is reactive under water and air .
hope it helps
1 atom Mg, 2 atoms O and 2 atoms H.
1 + 2 + 2 = 5, so correct answer is C
