As the intermolecular forces get weaker, the amount dissolved decreases. Ammonia can form hydrogen bonds with water thus allowing it to be more soluble. CO2 and O2 can only react through London forces, but since CO2 has a higher molecular mass, more electrons, it will have a larger in magnitude temporary dipole moment. This results in the CO2 being more soluble in water than O2.
The overall trend in solubility is NH3>CO2>O2
Answer:
these micronutrients are not produced in our bodies and must be derived from the food we eat.
Explanation:
Vitamins and minerals are micronutrients required by the body to carry out a range of normal functions. However, these micronutrients are not produced in our bodies and must be derived from the food we eat. Vitamins are organic substances that are generally classified as either fat soluble or water soluble.
Answer is: acid-base indicator or pH indicators.
Acid-base indicators are usually weak acids or bases and they are chemical<span> detectors for hydrogen or hydronium cations.</span>
Example for acid-base indicator is phenolphthalein (molecular formula C₂₀H₁₄O₄). Phenolphthalein is <span>colorless in </span>acidic<span> solutions and pink in </span>basic<span> solutions.
Another example is m</span><span>ethyl orange. It is red colour in acidic solutions and yellow colour in basic solutions.</span>
