Answer:
The cube A is magnesium, the cube B is aluminum and the cube C is silver.
Explanation:
Density is defined by the expression 
where m is the mass and V is the volume, therefore:
- Density of the cube A:
- Density of the cube B:
- Density of the cube C:
Solving for mass:
And all the three cubes have the same mass, so:
Therefore:
(Eq.1)
(Eq.2)
Solving for 
in Eq.1:
Replacing values for the volume:
As we know the density of the aluminum is 
, so replacing this value for 
:
that is the density of the magnesium.
Solving for 
in Eq.2:
That is the density of the silver.
Therefore the cube A is magnesium, the cube B is aluminum and the cube C is silver.
Answer:
Mass of chemical = 50 gram
Explanation:
Given:
Volume of chemical = 5 ml
Density of chemical = 10 g/mL
Find:
Mass of chemical
Computation:
Mass of chemical = Density of chemical × Volume of chemical
Mass of chemical = 10 × 5
Mass of chemical = 50 gram
Explanation:
lactic acid because of the acid it will release in the cellular respiration
The answer is (4). You may recall the term "radiometric dating," which refers to the dating of old artifacts by measuring proportions of certain radioactive isotopes they contain and making calculations based on their estimated half-lives. Geological formations are dated in this way.
Answer:
So, H2O means two atoms of hydrogen mixed with one atom of oxygen. All pure water is the same, two parts hydrogen to one part oxygen. ... Water cannot be separated by any physical means.
