4-true
Explanation:
The reaction rates depend on many factors, one of them is the amount of reagents, the temperature, and the presence or absence of catalyst.
Catalysts accelerate the reaction rate, as does the increase in the amount of reactants.
On the other hand, low temperatures, low amounts of reagents could slow down.
<h2>They would most likely be affected by dehydration. For humans, we cannot do without water because it is very essential in staying hydrated and for the body to work. For plants, they need the water to grow and produce food for the humans. </h2>
mol = 3.19 × 10^23/6.02^23
= 0.529 mol
mass = 0.529 × 52
= 27.508 g
g to decigram
= 27.508 × 10
= 275.08 decigram
Answer:
a) The higher the concentration, the higher the boiling point. You can think of this effect as dissolved solute crowding out solvent molecules at the surface, where boiling occurs. The higher the concentration of solute, the more difficult it is for solvent molecules to escape into the gas phase.
b ) The more concentrated a solution, the more the freezing point of water will be depressed. The solute particles basically interfere with the ability of the water molecules to freeze because they get in the way and make it more difficult for the water to hydrogen bond
