Answer:
Here's where orbital hybridization came into play. According to this theory, when the carbon atom is in an excited state, one of the two electrons located in the 2s orbital will get promoted to the empty 2pz orbital. As a result, carbon now has 4 unpaired valence electrons with which it can form four bonds.

Answer:
A. Calorimeter
Explanation:
A calorimeter is an apparatus that can be used to measure the quantity oh heat in a chemical reaction or the amount of heat that accompanies a physical change and also determine the specific heat capacity of a substance.
It is used extensively in physics, chemistry and the study of thermodynamics. In its simplest form, a calorimeter contains a thermometer which is attached to a container filled with water and suspended above a combustion chamber.
Answer: Option (A) is the correct answer.
Explanation:
Arrhenius acids are the species which dissociate to give hydrogen ions, that is, .
For example,
In the given example, HCN is donating the hydrogen ion therefore, it is an acid whereas is accepting the hydrogen ions so it acts as a base.
Whereas according to Arrhenius, bases are the species which dissociate to give hydroxide ions, that is, .
For example,
Thus, we can conclude that the statement only positive ion in solution is best describes the solution produced when an Arrhenius acid is dissolved in water.
