A chemical reaction with an initial quantity of 1.35 moles of gas is performed in a 4.50-L flask at 24.7°C and under 1.07 atm of

nexus9112 [7]

Answer:

0.488 mol

Explanation:

By the ideal gas law:

PV = nRT

Where P is the pressure, V is the volume, n is the number of moles, R is the gas constant (0.082 atm.L/mol.K), and T is the temperature in K. Thus, after the reaction:

P = 2.92 atm

V = 4.50 L

T = 55.2°C + 273 = 328.2 K

PV = nRT

n = PV/RT

n = (2.92*4.50)/(0.082*328.2)

n = 0.488 mol

Determine the ratio of amount NaOH reacting per unit amount FeCl3. Enter an integer that represents x mol NaOH/1 mol FeCl3.

earnstyle [38]

Answer is: the ratio of amount NaOH reacting per unit amount FeCl₃ is 3 mol NaOH /1 mol FeCl₃.

Balanced chemical reaction:
3NaOH(aq) + FeCl₃(aq) → 3NaCl(aq) + Fe(OH)₃(s).
NaOH is sodium hydroxide.
FeCl₃ is iron(III) chloride.
Coefficient for sodium hydroxide is three and for iron(III hydroxide is one.

Draw the structure of (z)-3-bromo-6-methyl-2-heptene. be sure the stereochemistry is drawn clearly.

Anna007 [38]

Explanation: In IUPAC, E-Z convention is given for describing the cis - trans notation to the isomers. According to CIP rule, the groups on the doubly bonded carbon atoms are given priorities based on the the atomic masses of first connected atom.

If the highest priority groups are on the same side, it is known as Z-form and if the highest priority groups are on opposite side, it is known as E-form.

We are given (Z)-3-bromo-6-methyl-2-heptene, in this the highest priority groups are bromine on one side and methyl- group on another side.

The structure is provided in the image below.
