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.

Have a nice day!

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
