The substances have different atomic masses, one is organic and one is inorganic, and Cl and Oxygen belong to different groups. There are more differences but these are the most basic ones.
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:
1. Phenolphthalein
2. Phenolphthalein
3. Methyl orange
Explanation:
Different indicators are used by knowing the relative strength of the acid and the bases I.e whether the acid is strong or weak, so also the base.
The following answers are obtainable:
1. Phenolphthalein
We use this indicator for a weak base and a strong acid. Formic acid is a weak organic acid while sodium hydroxide is a strong base
2. Phenolphthalein
We use this indicator because we are dealing with a strong acid and a strong base. Hydrochloric acid is a strong acid while potassium hydroxide is a strong base
3. Methyl orange
This is because we are dealing with a strong acid and a weak base
Answer:
Option d = terpenes
Explanation:
Terpenes:
It is unsaturated hydrocarbons extracted from the plants specially from pine and citrus. These are cyclic compound with the formula C₁₀H₁₆.
1. It is used as a solvent for natural products.
2. It is used in food , cosmetics and pharmaceutical industries.
3. It is very effective ingredients for agricultural pesticides.
4. It is used as a fragrance in perfumes.
5. As a flavoring agent it is also added into the beverages products.
6. It is highly concentrated and used in very small amount to create fragrances.
7. Its high concentration can led to the bad flavor and fragrances.
