The correct option is A. The band theory of metal explains how metals carry electricity by utilizing the electrons in their outer shells. When atomic orbitals of metals with similar energy levels merge, they create molecular orbitals and form bands. These bands facilitate the movement of electrons within metals, enabling them to conduct electricity.
The concentration of the HCl solution can be determined as follows:
The reaction equation is written as
NaOH + HCl = NaCl + H2O
Next, the moles of NaOH are calculated: moles = molarity x volume /1000
= 5 x 2/1000 = 0.01 moles
Using the mole ratio of NaOH to HCl, which is 1:1, the moles of HCl is also equal to 0.01 moles
The concentration is given by: concentration = moles/volume x 1000
= 0.01/10 x 1000 = 1M
-0° is the freezing temperature of ice or ice cream.
