A chemical reaction was used to produce 2.95 moles of copper(II) bicarbonate, Cu(HCO3)2.

BARSIC [14]

Answer:

About 547 grams.

Explanation:

We want to determine the mass of copper (II) bicarbonate produced when a reaction produces 2.95 moles of copper (II) bicarbonate.

To do so, we can use the initial value and convert it to grams using the molar mass.

Find the molar mass of copper (II) bicarbonate by summing the molar mass of each individual atom:

$\displaystyle \begin{aligned} \text{MM}_\text{Cu(HCO$_3$)$_2$} &= (63.55 + 2(1.01)+2(12.01)+6(16.00))\text{ g/mol} \\ \\ &=185.59\text{ g/mol} \end{aligned}$

Dimensional Analysis:

$\displaystyle 2.95\text{ mol Cu(HCO$_3$)$_2$}\cdot \frac{185.59 \text{ g Cu(HCO$_3$)$_2$}}{1 \text{ mol Cu(HCO$_3$)$_2$}} \Rightarrow 547 \text{ g Cu(HCO$_3$)$_2$ }$

In conclusion, about 547 grams of copper (II) bicarbonate is produced.

Yeast and other organisms can convert glucose (C6H12O6) to Ethanol (CH3CH2OH) through a process called Alcoholic Fermentation. T

Murljashka [212]

Answer:

The answer to your question is 8.28 g of glucose

Explanation:

Data

Glucose (C₆H₁₂O₆) = ?

Ethanol (CH₃CH₂OH)

Carbon dioxide (CO₂) = 2.25 l

Pressure = 1 atm

T = 295°K

Reaction

C₆H₁₂O₆ ⇒ 2C₂H₅OH(l) +2CO₂(g)

- Calculate the number of moles

PV = nRT

Solve for n

$n = \frac{PV}{RT}$

Substitution

$n = \frac{(1)(2.25)}{(0.082)(295)}$

Simplification

n = 0.092

- Calculate the mass of glucose

1 mol of glucose --------------- 2 moles of carbon dioxide

x --------------- 0.092 moles

x = (0.092 x 1) / 2

x = 0.046 moles of glucose

Molecular weight of glucose = 180 g

180 g of glucose --------------- 1 mol

x g ---------------0.046 moles

x = (0.046 x 180) / 1

x = 8.28 g of glucose

In this experiment, 1-2 mL of saturated sodium chloride is used to transfer the crude product after the initial distillation. Wh

lina2011 [118]

Saturated sodium chloride is used to transfer the product rather than water since it is not polar and rinsing the product with water would revert any 4-methylcyclohexene back to 4-methylcyclohexanol in the Hickman Head and thus lowering the percent yield; using water would shift the equilibrium towards the reactants. Also sodium chloride removes the small amount of phosphoric acid and also a small amount of water. If one were to add water, both 4-methylcyclohexene and phosphoric acid are partially soluble making difficult to remove the water later; sodium chloride makes the water less reactive so easier to remove by making the aqueous later more polar.
