Answer: 2. Heat flows from faster molecules to slower molecules when they collide.
Explanation: Hope this helped! :)
Acidity is caused by a losing <span>H+</span><span> ions. How acidic a substance is depends on how easily it will split with the hydrogen ions in water.
In your question, carboxylic acids are the most acidic because they have two oxygen atoms on the carbon to which the carboxyl group is attached, whereas the alcohol only has one and the alkyne has none, like I said earlier, this makes the hydrogen ion partially positive and therefore easier to lose.

If the patient is given 150 mL/h of IV saline for 1.5 h 1.97 g NaCl she receive.
<h3>What is Molarity ?</h3>
Molarity (M) is defined as the number of moles of solute dissolved in 1L of solution. Molarity is also known as Molar Concentration. The S.I unit of Molarity is molar (M) or mol/L.
It is expressed as:
Molarity (M) =
Molarity × Volume of solution = Number of moles
As we know that
Number of moles =
So,
Molarity × Volume of solution =
Molarity × Volume of solution × Molar Mass = Mass
Volume =
= 225 mL
Mass of NaCl = Molarity × Volume of solution × Molar Mass
= (0.15 mol/L NaCl) × (58.44 g/mol NaCl) × (225 ml × 0.001)
= 1.97 g NaCl
Thus from the above conclusion we can say that If the patient is given 150 mL/h of IV saline for 1.5 h 1.97 g NaCl she receive.
