How do both co2 and sio2 exist in lattice structure

SiO2 has a chain structure and Si is bonded to four oxygen atoms in the lattice structure. Due to the presence of vacant d-orbitals in Silicon, it can expand its covalency. ... But CO2 is linear in structure. Carbon bonded to two oxygen atoms by double bonds.

Explanation:

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
