Answer:
They would probably be equal L and D stereoisomers
Explanation:
All amino acid (except glycine) can occur in two isomeric forms called L- and D- forms, because of the possibility of forming two different enantiomers around the central carbon atom known as the chiral center. The two enantiomers, have identical physical and chemical properties, but their interactions with other chiral molecules may vary.
A carbon chiral center occcurs when the carbon is bonded to four different substituents. Glycine, has no enantiomers because it has two hydrogen atoms attached to the central carbon atom.
<em>When a compounds with chiral centers are synthesized in the laboratory randomly (in the absence of a directing template) left and right-handed molecules ( corresponding to L- and D- forms) of a compound will form in equal amounts known as a racemic mixture. This was the case when Louis Pasteur in 1848, investigated the crystalline sediment that accumulated in wine casks called paratartaric acid or racemic acid, a form of tartaric acid.</em>

Answer:
8 m
Explanation:
by using well known formula
To determine whether our equations are balanced, we must write the elements on the products side and also the reactants side. If the amount of the elements (coefficients and subscripts) are equal on both sides, we have a balanced equation.
Lets try (A)
2NaCl + H₂SO₄ → HCl + NaSO₄
Na=2 Na=1
Cl=2 Cl=1
H=2 H=1
Na=2 Na=1
S=1 S=1
O=4 O=4
Most of the elements here are not equal for both sides, therefore, A is not the answer.
Lets try (B)
2Na + S → 2NaS
Na=2 Na=2
S=1 S=2
This is a wrong answer because S is not equal on both sides. B is a wrong answer.
Lets try (C)
KOH + H2SO4 → KHSO4 + H2O
K=1 K=1
O= 1 O=1
H=1 H=1
H=2 H=2
S=1 S=1
O=4 O=4
THIS IS A BALANCED EQUATION!!!! ALL ELEMENTS ARE EQUAL ON BOTH SIDES!!!
Since we already know that C is our answer, we have no need to check D. Also, D is incorrect because N has 1 on reactants side, and 2 on the other. Therefore, we automatically know that D is wrong.
FINAL ANSWER: C IS OUR ANSWER, IT IS A BALANCED EQUATION. :)
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Thus, since the potassium bromide and silver nitrate are in a 1:1 mole ratio, the first step is to identify the limiting reactant, by considering the reacting volumes of reactants in order to compute the available moles of potassium bromide and the moles of potassium bromide consumed by the 15.4 mL of 0.512-M solution of silver nitrate:
In such a way, since less moles are consumed than available, we infer that silver nitrate is the limiting reactant, for which the resulting grams of silver bromide (molar mass 187.8 g/mol) result:
Best regards.
