Answers:
There's many factors, such as the temperature, rainfall, food available, and the surrounding terrain, that all can effect an animal's characteristics.
Answer:
Δ
Explanation:
Hello,
A. In this part, we must include the heat effect for pentane and water:
B. In this part, we just consider the previously computed heat and divide it by the sample of pentane as follows:
Δ
Best regards.
Answer:
See explanation below
Explanation:
Water has the anomality of having the solid less dense than the liquid state. The reason for this is that the hydrogen bonds in the solid ice forces the molecule to occupy more room to properly have the stability afforded by the hydrogen bonds. That is the reason why ice floats on water.
The other interesting consequence of this anomality is that the slope of the solid/liquid phase boundary is negative since at higher pressures the ice can be changed to its liquid phase which can be seen from the negative slope of the solid/liquid boundary.
A) True
B) False
C) False
D) True
E) False
F) True close up to 4 ºC when the water molecules start to behave like other liquids, that is the density of the liquid decreases.
G) True
H) True ( repeated question)
The hybrid atomic orbitals are formed by the combination of the valence orbitals on an atom. The hybrid orbitals formed have different energy and shape compared to the atomic orbitals that combine to form the hybrid orbitals. Hybrid orbitals help in explaining the shapes of the molecules and other bonding properties.
Therefore the correct answer will be,
b. A mixture of the valence orbitals in an atom
e. There are as many hybrid orbitals as there are valence orbitals that mix together.
f. Hybrid orbitals have a different shape and different energy than the atomic orbitals of which they are made
