Aluminium chloride

Chemical compound

DescriptionAluminium chloride is the main compound of aluminium and chlorine. It is white, but samples are often contaminated with iron(III) chloride, giving it a yellow color. The solid has a low melting and boiling point. Wikipedia

IUPAC ID: aluminium chloride

Molar mass: 133.34 g/mol

Soluble in: Water

Related Lewis acids: Iron(III) chloride; Boron trifluoride

Heat capacity (C): 91.1 J/mol·K

<span>The correct option is C.i.e. AlCl3 Given: The valence of aluminum is +3, and the valence of chlorine is –1. Thus, 3 chlorine atoms each of (-1 charge )combine to make the charge balance because of Al (3+). Thus, 1 atom of Aluminum (Al) binds with three atoms of Chlorine (Cl).Thus, the net foromula becomes AlCl3</span>

Glucose, C6H12O6, is used as an energy source by the human body. The overall reaction in the body is described by the equation C

Crank

Answer:

70.3824 grams of carbondioxide is produced.

Explanation:

$C_6H_{12}O_6(aq)+6O_2(g)⟶6CO_2(g)+6H_2O(l)$

Moles of glucose = $\frac{48.0 g}{180 g/mol}=0.2666 mol$

According to reaction 1 mole of glucose reacts with 6 mole of oxygen gas.

Then 0.2666 mol of gluocse will reactwith :

$\frac{6}{1}\times 0.2666 mol =1.5996 mol$ of oxygen

Mass of 1.5996 moles of oxygen gas:

$1.5996 mol\times 32 g/mol = 51.1872 g$

51.1872 grams of oxygen are required to convert 48.0 grams of glucose to $CO_2$ and $H_2O$ .

According to reaction, 1 mol, of glucose gives 6 moles of carbon dioxide.

Then 0.2666 moles of glucose will give:

$\frac{6}{1}\times 0.2666 mol =1.5996 mol$ of carbon dioxide

Mass of 1.5996 moles of carbon dioxide gas:

$1.5996 mol\times 44 g/mol = 70.3824 g$

70.3824 grams of carbondioxide is produced.
