<span>I start the reaction below with 1.5g of Al, how many moles of Cl can I make" (Al + Cl2 ➡ NaCl)

First thing to do is find out what the amu of Al is.
You can find that on a periodic table. 26.98grams per mole
1.5g Al x </span>\frac{1 mole Al}{26.98g Al} = <span>0.05559673832 = 0.056 moles of Al
Now ratio the moles.
0.056 moles Al x </span>\frac{1 mole Cl}{1 mole Al} = 0.056 moles of Cl
The answer is 0.056 moles of Cl

Identify which one of the three methods of analysis (i.e., TLC, IR and melting point) provides information about the structure o
Alex787 [66]

Answer:

IR provides structural information about a molecule. TLC and melting point analysis do not provide structural information.

Explanation:

IR gives information about the functional groups present in a molecule. The vibrational frequency of each functional group gives information about the structure of the entire molecule.

Structural features of a molecule are deduced by matching the vibrational frequencies of  groups obtained from the IR spectroscopy with that of known functional groups in literature.

Melting point is a qualitative method that can only yield information about the identity of a compound and not its structure. Each compound has its unique melting point recorded in literature and any pure sample of the same compound must have the same sharp meting point.

Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures. After separating the components of the mixture, it does not give any information regarding the identity or the structure  of the components of the mixture.

Therefore, only IR yields structural information about a sample.

ladessa [460]

Answer:

carbon dioxide is fixed or incorporated into organic molecules.

Explanation:

Carbon dioxide fixation is the conversion of inorganic carbon into organic carbon.

In photosynthesis CO2 is converted into glucose i.e inorganic carbon (CO2) is converted into organic molecule (glucose).

Why are sulphur and oxygen in group 6 in terms of electronic configuration
Irina-Kira [14]

Answer: Because sulfur is directly below oxygen in the periodic table, these elements have similar electron configurations. As a result, sulfur forms many compounds that are analogs of oxygen compounds, as shown in the table below. ... O=O. double bonds are much stronger than S=S double bonds.
