Write complete ionic equation to show the reaction of aqueous hg2(no3)2 with aqueous sodium chloride to form solid hg2cl2 and aq
2 answers:
First we start with our molecular equation to ensure all atoms are balanced in order to maintain the law of conservation of mass.
.
The equation is unbalanced since we have 1 Cl atom on left hand side as opposed to 2 on the right hand side and we have 2 molecules on left hand side and 1 on the right hand side. So we add a coefficient of 2 on both the
and
The reaction occurs between solutes that are soluble in water to give a solid as a precipitate. So the complete ionic equation will show the soluble compounds in their dissociated states as ions in water and the insoluble compound as a solid.

The question is incomplete, complete question is:
Classify these bonds as ionic, polar covalent, or nonpolar covalent.
Na-F
P-Cl
Cl-Cl
Answer:
Na-F : The bond present is ionic bond.
PCl : The bond present is polar covalent bond.
ClCl : The bond present is non polar covalent bond.
Explanation:
1) Ionic bonds are defined as the bonds which are formed by the complete transfer of electrons from cation (positively charged ions) to anion (negatively charged ions). For Example: NaCl, etc.
Ionic compound :This compound is formed when difference in electronegativity between the atoms is very large.
2) Covalent bond is defined as the bond which is formed by the sharing of electrons between the atoms. For Example: HCl, etc.
Polar covalent compound: This compound is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example: etc..
Non-polar covalent compound: This compound is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: etc.
Na-F : Two different atoms with high electronegativity difference
Ionic compound because sodium is metal and fluorine is non metal and the difference between their electronegativity is very large.The bond present is ionic bond.
PCl : Two different atoms with low electronegativity difference
Polar covalent compound because phosphorus and fluorine both are non metal and the difference between their electronegativity is not very large.The bond present is polar covalent bond.
ClCl : Two same atoms with nil electronegativity difference.
Non Polar covalent compound because both are chlorine atom (non metal) and the difference between their electronegativity is zero.The bond present is non polar covalent bond.
<u>Answer:</u> The final volume of lungs is 621.5 mL
<u>Explanation:</u>
To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Hence, the final volume of lungs is 621.5 mL
