The transport of O2 from the outside air to tissue cells and the transport of CO2 from tissue cells to the outside is known as.... gas exchange.
Answer:
The percentage of germanium in germatite is 6.0003%.
Explanation:
Mass of an ore of germanite = 1.00 grams
Mass of germanium chloride = 0.177 grams
Percentage of germanium in germanium chloride = 33.9%
Let the mass of germanium present in germanium chloride be x.
Percentage of an element in a compound:
x = 0.060003 grams
Percentage of germanium in an ore of germanite:
The percentage of germanium in germatite is 6.0003%.
Answer:
Resonance
Explanation:
Resonance is an idea in chemistry that is used to explain such properties as equal bond lengths, bond angles and some other chemical behaviours. Resonance structures show the possible distribution of electrons in molecules. All the contributing canonical or resonance structures give a clue regarding the true structure of the chemical specie under consideration.
The true structure of the specie is somewhere in between that of all the contributing canonical structures. Resonance is often employed to explain properties such as equal bond lengths and bond angles just as typified in the question under consideration.
Answer:
The freezing point depression can be calculated using the pure solvent freezing point and the molality of the solution.
At the freezing point, the vapor pressure of both the solid and liquid form of a compound must be equal.
The freezing point of a substance is the temperature at which the solid and liquid forms are in equilibrium.
To reattain equilibrium, the freezing point of the solute and solvent mixture is lowered relative to the original pure solvent.
1) Floats --- Density of the fluid is higher
2) Floats --- Density of the fluid is higher
3) Niether -- Same level of density
4) Neither -- Same density
5) Sink -- Object has higher density
6) Floats-- Fluid has higher density
