Answer:
Spices
Explanation:
Herbs are the leaves.
Vegetables are the seeds.
Fruits are the seeds.
So spices are the only option left.
Answer:
The false statement is B.
Explanation:
When the temperature in a reaction increases, the rate of this reaction increases.
It means that it would be more probably to each molecule in the system collides but that does not mean that the reaction will happen faster because there is other factors that affect the velocity of the reaction, such as concentration of reactants, presence of catalyst, and activation energy.
Also, the nature itself of the reaction can affect the velocity, due to some of chemistry reactions occur instantaneously without increasing the temperature and in the case you increase the temperature the reaction will not occur quickly.
On the other hand, the size of the particle will affect the rate due to smaller particles are able to move faster than larger ones under high Temperature.
Answer:
Solution is 4.67% by mass of salt
Explanation:
% by mass is the concentration that defines the mass of solute in 100g of solution.
In this case we have to find out the mass of solution with the data given:
Mass of solution = Mass of solute + Mass of solvent
Solute: Salt → 14.2 g
Solvent: Water → 290 g
Solution's mass = 14.2 g + 290g = 304.2 g
% by mass = (mass of solute / mass of solution) . 100
(14.2 g / 304.2g) . 100 = 4.67 %
