The answer is C because the particles in a solid are so tightly packed that there are no spaces in between them and they cannot move around.
Answer:
C) The mass will double.
Explanation:
The amount of solute that will dissolve will also double since the solvent volume has doubled.
There is a fine liner relationship between amount of solute and solvent that can form a solution.
- A solute is the substance that is dissolved in another.
- A solvent is the medium by which a solute is dissolved.
- A combination of solute and solvent forms a mixture called solution.
To form a solution, solvation must take place. During solvation, the molecules of the solvent surrounds the solute completely and bring them into the phase of dissolution.
Generally, the more the solvent, the more the solute it is able to dissolve.
A table spoon of sugar for example will dissolve readily in a jar of water without settling. In a bucket, it is even much more easier.
The correct answer would be the last one.
Answer:
There is no percent left for other foods
Explanation:
The total energy consumed was:
E = 2x1.2x10⁶ + 3x6.7x10⁵ =
E = 4.41x10⁶ J
Knowing that 1 cal = 4.184 J
1 cal --------- 4.184 J
y ---------------- 4.41x10⁶ J
By a simple direct three rule:
4.184y = 4.41x10⁶
y = 1.05x10⁶ cal
Which is higher than the 2000 calorie daily food intake, so there is no percent left for other foods.
Answer:
No
Explanation:
It is not correct to say that an object with the largest volume has the largest mass.
Mass and volume are not directly related. In fact, the relationship between them can be direct or inverse.
Mass is the amount of matter in a substance. Volume is the space a body occupies.
- A balloon and a stone for example is a typical one.
- A balloon has more volume but far lesser mass compared to a stone.
- A stone, gravel sized has low volume but more massive than a balloon.
Therefore, it is wrong to say a balloon has more mass because it has more volume.
