The rate of reaction increases to counter the action of removing heat.
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
Answer:
12.4 mol O2
Explanation:
4Al + 3O2 -----> 2Al2O3
from reaction 4 mol 3 mol
given 16.5 mol x mol
x = 16.5*3/4 =12.4 mol O2
Answer:
Resistance resist the flow of current. This means that if 5V go through a resistance, it'll be reduce down to something below or equal to 5V.
If it gets reduce below 5V, lets say it goes down to 3V, the extra 2V must go somewhere. That 2V energy is converted to heat and dissipated through the resistor.
If there's a big current then the energy dissipated will be huge. And more negery = more heat which can cause fire and burn you.
