Sublimation;When anything solid turns into a gas without first becoming liquid, <span> When the surface layer of snow or ice turns into fog or steam without melting, </span>
Answer: 1
Explanation:
Stomach acid, or gastric acid, has a pH range of 1.5 to 3.5. The most likely pH in this situation would therefore be 1
Answer:
Olivia ?? depends
Explanation:
I have the same question but if yours is different from mine than that's not the answer. Janema Olivia Michael
Trial #1 46.1 g 50.1 g 53.1 g
Trial #2 47.8 g 50.2 g 53.0 g
Trial #3 53.1 g 50.2 g 53.2 g This is what my chart looks like and you can see Olivia's is the most consistent :)
The answer is b it will always be equal
1.4406 × 10⁻⁶ is the Ka(dissociation constant) for the acid.
The equilibrium constant for the reaction of an acid with water is the acid dissociation constant, where the acid, HA separates into H⁺ and A⁻ ions.
The acid dissociation constant is represented by (Ka).
So let's first imagine that the given monoprotic acid is HA.
HA will dissociate into H⁺ and A⁻ ions.
HA ⇒ H⁺ and A⁻
The formula used for Ka is
Ka = [H⁺] [A⁻] / [HA]
Given
pH = 2.83
[HA] = 1.50 M
From the given pH, we can calculate [H⁺] and [A⁻]
[H⁺] = [A⁻] = 1 ×
= 1.47 × 10⁻³ M
Ka = 1.47 × 10⁻³ × 1.47 × 10⁻³ / 1.50
Ka = 1.4406 × 10⁻⁶
Hence, 1.4406 × 10⁻⁶ is the Ka for the acid.
