Answer:
carbon monoxide, CO, can be thought of as having two ordinary covalent bonds between the carbon and the oxygen plus a coordinate bond using a lone pair on the oxygen atom
Explanation:
Answer:
Therefore, 2 moles of oxygen will be required to oxidize 2.66 moles of oxygen. 72g of Aluminium will be completely oxidized by 44.8 lit of oxygen at STP.

The two liquids made a new substance.
<h3>What is a physical and chemical change?</h3>
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity.
A chemical change occurs when some substances are transformed into different substances, with different nature and properties. In this case when both liquids are mixed a solid is formed. This is an example of a change of state of the liquids reactants to the solid product, which has properties and characteristics different from that of the initial liquids of the mixture which is called a chemical change.
Hence, option D is correct.

P= 1.50 atm
V= 3 L
R= 0.08205<span> L∙atm/mol∙K
T= 300 K
n= ?
we all this information, we can tell that we need to use ideal gas formula
PV= nRT
if we rearrange the formula for n, we get--> n= PV/ RT
let's plug in the values.
n= 1.5 x 3/ (0.08205 x 300)= 0.18 moles
