What is the product of the reaction of an alcohol and a carboxylic acid when heated together

Chemistry

Answer:

Explanation:

The direct reaction of a carboxylic acid with an amine would be expected to be difficult because the basic amine would deprotonate the carboxylic acid to form a highly unreactive carboxylate. However when the ammonium carboxylate salt is heated to a temperature above 100 C water is driven off and an amide is formed.

At higher temperatures,

valentinak56 [21]

Answer:

reaction rates increase because reactants move faster, collide more often, and produce more collisions with the required energy of activation.

Explanation:

At higher temperatures, the reactant atoms gain high kinetic energy which decreases the intermolecular forces of attraction between these atoms/molecules.

Hence the rate of collision is very high which decreases the activation energy and products are formed with in a short period of time.

The following two reactions are important in the blast furnace production of iron metal from iron ore (Fe2O3):2C(s) + O2(g) -&gt

Inga [223]

Answer: A) 67.1 moles

Explanation:

The balanced reaction is :

$2C(s)+O_2(g)\rightarrow 2CO(g)$

$Fe_2O_3+3CO(g)\rightarrow 2Fe+3CO_2$

To calculate the moles, we use the equation:

$\text{Number of moles of iron}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{5.00\times 1000g}{56g/mol}=89.3moles$

According to stoichiometry;

2 moles of iron is produced by 3 moles of carbon monoxide

89.3 moles of iron is produced by= $\frac{3}{2}\times 89.3=134$ moles of carbon monoxide

2 moles of carbon monoxide is produced by = 1 mole of oxygen

Thus 134 moles of carbon monoxide is produced by = $\frac{1}{2}\times 134=67.1$ moles of oxygen

How many kilograms of gasoline fill a 12.0-gal gas tank

Sergeu [11.5K]

Answer:

29.98kg

Explanation:

12.0 gallons * (3.78541178 liters/gallon) * (1000 mL/liter) * (0.66 g/mL) * (1 kg/1000 g) = 29.98 kg

The low-grade iron ore taconite, which contains Fe3O4, is concentrated and made into pellets for processing. If one ton of tacon

xenn [34]

Answer: The percent composition of $Fe_3O_4$ in taconite is 37.6 %.

Explanation:

We are given:

Mass of taconite pellets = 1 ton = 907185 g (Conversion factor: 1 ton = 907185 g)

Mass of iron produced = 545 lb = 247212 g (Conversion factor: 1 lb = 453.6 g )

We know that:

Molar mass of iron = 55.85 g/mol

Molar mass of $Fe_3O_4$ = 231.53 g/mol

1 mole of $Fe_3O_4$ contains 3 moles of iron atom and 4 moles of oxygen atom

(3 × 55.85) = 167.55 g of iron is produced from 231.53 grams of $Fe_3O_4$

So, 247212 grams of iron will be produced from = $\frac{231.53}{167.55}\times 247212=341611.43g$ of $Fe_3O_4$

To calculate the percentage of $Fe_3O_4$ in taconite, we use the equation:

$\%\text{ composition of }Fe_3O_4=\frac{\text{Mass of }Fe_3O_4}{\text{Mass of taconite}}\times 100$

Mass of taconite = 907185 g

Mass of $Fe_3O_4$ = 341611.43 g

Putting values in above equation, we get:

$\%\text{ composition of }Fe_3O_4=\frac{341611.43g}{907185g}\times 100=37.6\%$

Hence, the percent composition of $Fe_3O_4$ in taconite is 37.6 %.
