When making a solution by diluting a stock solution. Suppose when a solid is stirred into a liquid and dissolves,
a homogenous mixture is formed. When the mixture does not dissolve, the mixture
is heterogeneous.
Answer:
113
Explanation:
We are given that the atom of cadmium has 66 neutrons:
Number of neutrons in Cd = 66
Now;
Mass number = ?
The mass number of an element is the sum of the number of protons and number of neutrons
Mass number = number of protons + number of neutrons
By the position of cadmium, it has an atomic number of 47 and this is the number of protons
Mass number = 47 + 66 = 113
Answer :
The steps involved in the electron-dot structure of given molecule are :
Step 1 : First we have to determine the total number of valence electron in a molecule.
Step 2 : Draw the skeleton of the molecule.
Step 3 : Placing a bonding pair of electrons between the atoms to form the chemical bonds.
Step 4 : The rest of the electrons are used as a lone pair for central or terminal atoms to achieve an octet to finish the electron-dot structure.
All the electron-dot diagram of given molecule is shown below.
