B and C are in excess so amount of E will be determined by A.
Amount of product is determined by limiting reagents - Always.
Hence 6 moles of E will be formed.
Hope this helps!
Answer:
I don't wanna intrigue but I think this is how you want things to go. But to make it easier all you have to do is look up "what is genomics" and then simply answer each question should take maybe 5-7 minutes. Just trying to help :)
Answer:
0,0,0,0
Explanation:
The formal charge formula:
So:
Hydrogen: 1 elec. of valence and shares two electrons with the O
Oxygen: 6 elec. of valence, 2 lone pairs and shares two electrons with the H and two with the F
Fluorine: 7 elec. of valence, 6 lone pairs and shares two electrons with the O
Oxygen: 6 elec. of valence, 3 lone pairs
Note: the dative bond between F and the second O doesn't count as shared electrons.
The particles of the solute leave each other and become surrounded by particles of the solvent.
Answer:
Explanation:
The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction. This can be gleaned from the third postulate in Dalton's series. Magnesium oxide decomposes into magnesium and oxygen. If 4.03 g of magnesium oxide decomposes to form 2.43 g of magnesium, what mass of oxygen gas is also released in the reaction
The word say magnesium oxide decomposes to magnesium and oxygen
the chemical symbols say
MgO-----------> Mg + O2 (since natural oxygen is diatomic)
the balanced equation says
2MgO-------------->2Mg + O2
4.03 gm----------> 2.43 + ?0 gms
tour high school Algebra I class says
? = 4.03 -2.43 =1.60
your chemical analytcal lab says %mO in MgO = 16/40.3 = 39.7%
your calculator says
39.7/100 X 4.03 = 1.60
all of these prove the law of conservation of mass
