A 5.5 g sample of a substance contains only carbon and oxygen. Carbon makes up 35% of the mass of the substance. The rest is mad
Umnica [9.8K]

We have been given the condition that carbon makes up 35% of the mass of the substance and the rest is made up of oxygen. With this, it can be concluded that 65% of the substance is made up of oxygen. If we let x be the mass of oxygen in the substance, the operation that would best represent the scenario is,

<span>                                       x = (0.65)(5.5 g)</span>

<span>                                       <em> </em><span><em>x = 3.575 g</em></span></span>

What happens to the density of a substance when it is heated? Explain your answer.
hoa [83]

Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density. Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density.

Bad White [126]
Correct Answer: option B. moderately polar covalent 

Reason: 
Both phosphorus and oxygen are non-metals, and hence they are bonded by covalent bonds. Furthermore, the electro negativity of P and O is 2.1 and 3.5 respectively. The difference in electro negativity is 1.4. Due to the difference in electro negativity, nature of the P-O bond in phosphorus pentoxide (P2O5) is moderately polar covalent.
