The right answer is the first molecule (3-methyl-butan-2-one).
There are many bands around 2900-3000 cm-1 proving the presence de C-H bound.
There an intense band in 1700 cm-1 proving the presence of C=O.
There's no band proving the presence of aromatic structure, C=C bond nor C-N bond.
To balance the chemical reaction above, we need to remember that the amount of the elements in the reactant side should be equal to the amount of that element in the product side. The balanced chemical reaction is written as:
<span>N2O5 +H2O --->2HNO3</span>
Answer:
A solution that is 0.10 M HCN and 0.10 M LiCN
Explanation:
- A good buffer system contains a weak acid and its salt or a weak base and its salt.
- In this case; A solution that is 0.10 M HCN and 0.10 M LiCN, would make a good buffer system.
- HCN is a weak acid, while LiCN is a salt of the weak acid, that is, CN- conjugate of the acid.
The particles are atoms, his theory is the atomic theory
M1V1 = M2V2
M1 = 3.000 M
V1 = 0.8000 L
M2 = ?
V2 = 2.00 L
M2 = M1V1/V2 = (3.000 M)(0.8000 L)/(2.00 L) = 1.20 M
