CO cause polyatomic means many types of atom.
S8 only contain one type of atom - S
Na only contain one type of atom - Na
Cl2 only contain one type of atom - Cl
CO contains two types of atoms - C and O
Moles of oxygen = mass/molar mass of O2 = 8/31.998 = 0.25 moles.
Number of particles = moles x 6.02 x 10^23 = 0.25 x 6.02 x 10^23 = 1.505 x 10^23 particles.
Hope this helps!
I'd recommend checking out some videos on youtube to get some good examples worked out, for example, the video "<span>How to Balance Chemical Equations in 5 Easy Steps: Balancing Equations Tutorial" is done well.</span>
Liquid antacids contain suspensions of bases like aluminum hydroxide and magnesium hydroxide. These are usually the bases that can neutralize the stomach acids.
The chemical equation representing the neutralization reaction of stomach acid, HCl and antacid, aluminum hydroxide: Three moles of hydrochloric acid reacts with one mole aluminum hydroxide to give the salt, aluminum chloride and three moles of water.
1,2,3, or 4. Generally, carbon likes to make 4 bonds to 4 different atoms. For example, in methane(CH4), Carbon makes 4 bonds to 4 hydrogens. However, Carbon can also make double and triple bonds to atoms. This means that of the 4 bonds, more are used to bond to one thing. For example, in the compound CN, Carbon bonds to hydrogen on one side and triple bonds to Nitrogen on the other. This shows carbon can bond to at 2 atoms as well as 4 at a time. using a one double bond carbon would only bond to 3 atoms. I cant think of an example where carbon only bonds to one other atom without breaking the octet rule, but all the other values can be validated through examples. So, I still think the bottom answer is correct. Hope this helped!
