Answer:
-OOH
Explanation:
This forms an acid if it comes in contact with a metal
Hi, thank you for posting your question here at Brainly.
The acid dissociation constant, Ka, is an equilibrium constant that measure the strength of an acid. It is a ratio of the concentration of the products (salt and water) and the reactants (acid). The higher the Ka, the more tendency it is to favor the product side, which means more tendency to donate H+ ions. This is exactly the definition of a strong acid (high H+ ionized).
Thus, the answer is letter D.
Answer:
= 0.25 g MgSO4
Explanation:
0.10% implies that the solution will contain 0.1 g of magnesium sulfate, for every 100 mL of solution.
Therefore;
= 250 g × 0.1 g/100 mL
= 0.25 g MgSO4
A. Evaluating test results is your answer. Let me know if this is correct!
