What solid contains two types of bonds?

a.) iodine
b.) silicon (iv) oxide
c.) nacl
d.) zinc

The correct answer is B.

Explanation:

Silicon (IV) Oxide has two different types of bonds. Each silicon atom is bonded by simple covalent bonds to four oxygen atoms. In turn, each oxygen atom is bonded with bonds. simple covalent to two other silicon atoms forming a network. In this atomic crystalline network, there are twice as many silicon atoms as there are oxygen atoms. This can be seen by observing its chemical formula.

The Silicon (IV) Oxide molecules form a three-dimensional (quartz) network, which is part of a large covalent network, formed by continuous covalent bonds.

the answer is na (sodium)

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
