Density= mass/volume
= 100/25
density = 4g/ml
The concentration of hydrogen can be shown as:
[H+ ] = 3 * 10-5 M
pH can be determined as:
pH = - log [H+ ]
= - log (3 * 10-5)
= 4.53
Thus the pH of solution is 4.53
Density of boat =
=
= 0.88 g / cm³
Since the density of water is greater than the density of the boat ( 1 > 0.88) then that means,
the boat will NOT sink.B.
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.
Answer:
Explanation:
A. Linear Relationships
x 2 4 6 8 10 12
y 4.4 8.8 13.2 17.6 22 26.4
(you can plot this by using the (x,y) coordinates for each pair above.)
B. y=2.2x
mass is 2.2 times larger than the volume.
C. The mass is 2.2 times the volume.
