Answer:

Balancing Strategies: To balance this reaction it is best to get the Oxygen atoms on the reactant side of the equation to an even number. Once this is done everything else falls into place. Put a "2" in front of the NaClO3. Change the coefficient in front of the O2.

Six atoms of the peptide bond group are always planar due to the ____________. Dipole of amide linkage of a peptide bond is due

ycow [4]

Answer:

Explanation:

Resonance because the lone pairs undergo resonance due tothe partial bond relationship BTW Carbon - Nitrogen bond so the bond length shortens making the six atoms of peptide bond planar

And positive because The dipole of amide linkage of a peptide bond is as a result of the partially positively charged carbonyl oxygen and partially positively charged amide oxygen.

And the negative because The carboxylic acid group -COOH is an acid donates H+ and -NH2 being a base is H+ so causes a partial negative charge to develop on -COO(-) and partial positive charge to develop on -NH3(+).l

How many grams of LiOH are produced from 9.89 g of Li?

Nonamiya [84]

Taking into account the stoichiometry of the reaction, 34.12 grams of LiOH are produced from 9.89 g of Li.

In first place, the balanced reaction is:

2 Li + 2 H₂O ⇒ 2 LiOH + H₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Li= 2 moles
H₂O= 2 moles
LiOH= 2 moles
H₂= 1 mole

The molar mass of each compound is:

Li= 6.94 g/mole
H₂O= 18 g/mole
LiOH= 23.94 g/mole
H₂= 2 g/mole

By reaction stoichiometry, the following amounts of mass of each compound participate in the reaction:

Li= 2 moles× 6.94 g/mole= 13.88 g
H₂O= 2 moles× 18 g/mole= 36 g
LiOH= 2 moles× 23.94 g/mole= 47.88 g
H₂= 1 mole× 2 g/mole= 2 g

Then you can apply the following rule of three: if by reaction stoichiometry 13.88 g of Li produce 47.88 g of LiOH, 9.89 g of Li produce how much mass of LiOH?

$mass of LiOH=\frac{9.89 g of Li*47.88 g of LiOH}{13.88 f of Li}$

Solving:

mass of LiOH= 34.12 grams

Finalli, 34.12 grams of LiOH are produced from 9.89 g of Li.
