Answer:

L Group

Explanation:

Proteins are made up of amino acids, these amino acids determine the protein's functional groups, in the image I annexed you can observe that amino acids have an amino group (NH2), an acid group(COOH) and a R group, a lateral chain that varies depending on the amino acid, in the protein these amino acids are linked through a peptide bond leaving <em>one side of the chain with an acid group and the other side with an amide chain, keeping the R groups as well.</em>

I hope you find this information useful and interesting! Good luck!

16 mol of oxygen were react with excess hydrogen gas, how many moles of water would be produced
german
2H₂  +  O₂   →   2H₂O

mole ratio of O₂  :  H₂O     is     1  :  2

∴  if moles of O₂ = 16 mol

then moles of H₂O = (16 mol ×  2)

                               =  32 mol

Im hvaing a hard time getting the right answer
Tanya [424]

Answer:

V=23.9mL

Explanation:

Hello!

In this case for the solution you are given, we first use the mass to compute the moles of CuNO3:

n=2.49g*\frac{1mol}{125.55 g}=0.0198mol

Next, knowing that the molarity has units of moles over liters, we can solve for volume as follows:

M=\frac{n}{V}\\\\V=\frac{n}{M}

By plugging in the moles and molarity, we obtain:

V=\frac{0.0198mol}{0.830mol/L}=0.0239L

Which in mL is:

V=0.0239L*\frac{1000mL}{1L}\\\\V=23.9mL

Best regards!
