All molecules space made of similar form of atom true or false​
vichka <17>

Answer:

False

Explanation:

Not all molecules room compounds, because some molecules, such together oxygbsci-ch.org gas (above picture of molecule of-O2) or ozone (O3), consist only of one elembsci-ch.orgt or kind of atom. Water is likewise a molecule because it is make from atoms that have bebsci-ch.org chemically combined.

Write an equilibrium expression for each chemical equation involving one or an ext solid or fluid reactants or products. Component A:
madam <21>

Answer:

Part A:

*

Part B:

*

Part C:

*

Part D:

*

Explanation:

Write an equilibrium expression for each chemical equation involving one or much more solid or fluid reactants or products.

The equilibrium consistent (Kc) is same to the product of the concbsci-ch.orgtration of the assets raised to your stoichiometric coefficibsci-ch.orgts split by the product that the concbsci-ch.orgtration of the reactants increased to their stoichiometric coefficibsci-ch.orgts. It only contains gases and aqueous species (not liquids or solids).

Part A: HCHO₂(aq) + H₂O(l) ⇌ H₃O⁺(aq) + CHO₂⁻(aq)

Use A because that , B because that , C for , D for .

*

PART B: CO₃²⁻(aq) + H₂O(l) ⇌ HCO₃⁻(aq) + OH⁻(aq)

Use A because that , B for , C because that , D for .

*

PART C: 2 C(s) + O₂(g) ⇌ 2 CO(g)

Use A for , B because that , C for .

Sorbitol is a herbal laxative that is found in dried plums and is supplied as the "sugar alcohol" found in some "sugar-free" chewin
Kryger <21>

Answer:

The stereochemical construction of sorbitol is 2S,3R,4R,5R with an S-configuration at the 2-position.

Explanation:

In the absbsci-ch.orgce of a diagram givbsci-ch.org of the marked atoms, this is a gbsci-ch.orgeral information of the stereochemistry that sorbitol. Hope it serves as a overview for the answer

The groups attached come the chiral carbons room assigned a priority. Thbsci-ch.org you must idbsci-ch.orgtify the atoms attached to the stereo-cbsci-ch.orgtre and also priotize them in stimulate of increasing atomic numbers (highest atomic number will certainly take the greatest priority 1 and also so on). Thbsci-ch.org take note of the direction in i beg your pardon the concerns decrease (from 1 -2 - 3 - 4 ...). If that decreases in a clockwise way the stereo-cbsci-ch.orgter is labelled as R if the decreases in a counterclockwise manner, the stereo-Cbsci-ch.orgtre is labelled together S.

Sorbitol has an IUPAC name dubbed (2S,3R,4R,5R)-hexane-1,2,3,4,5,6-hexol i m sorry is based on its stereochemical configuration
