\[Zn + 2HNO3 → Zn(NO3)2 + H2\]
(a) Write an equation for the reaction between zinc and dilute nitric acid.
\[CO2 is a non-polar molecule because its linear geometry and symmetrical arrangement of polar C=O bonds result in a net dipole moment of zero.\] a level h2 chemistry 2012 paper 1 answers
\[CO2 has a linear molecular geometry, with a central carbon atom bonded to two oxygen atoms through double bonds. The carbon atom is sp hybridized, with two sp hybrid orbitals forming σ bonds with the oxygen atoms and two unhybridized p orbitals forming π bonds.\]
(a) Describe the bonding in CO2.
(b) Explain why the reaction between zinc and dilute nitric acid produces hydrogen gas.
\[Ionization energy is the energy required to remove an electron from an isolated gaseous atom.\] \[Zn + 2HNO3 → Zn(NO3)2 + H2\] (a)
\[Ethalal can be prepared by oxidizing ethanol using a mild oxidizing agent, such as potassium dichromate(VI) in acidic conditions.\]
