Given the balanced equation 2C4H10 + 13O2 → 8CO2 + 10H2O, how many moles of CO2 are produced when 14.9g of O2 are used?
Anna [14]

Answer: The number of moles of CO_2 produced are, 0.287 moles.

Explanation : Given,

Mass of O_2 = 14.9 g

Molar mass of O_2 = 32 g/mol

First we have to calculate the moles of O_2

\text{Moles of }O_2=\frac{\text{Given mass }O_2}{\text{Molar mass }O_2}

\text{Moles of }O_2=\frac{14.9g}{32g/mol}=0.466mol

Now we have to calculate the moles of CO_2

The balanced chemical equation is:

2C_4H_{10}+13O_2\rightarrow 10H_2O+8CO_2

From the reaction, we conclude that

As, 13 mole of O_2 react to give 8 moles of CO_2

So, 0.466 mole of O_2 react to give \frac{8}{13}\times 0.466=0.287 mole of CO_2

Therefore, the number of moles of CO_2 produced are, 0.287 moles.

Aspirin was formed to reduce the irritation of salicylic acid. However, aspirin can still disturb the stomach. Which functional
nataly862011 [7]

Answer:

Carboxylic acid

Explanation:

Asprin is a drug that contains the carboxylic acid functional group (R-COOH), ester functional group (R-O-CO-R') and the aromatic group (benzene ring).

When we take in aspirin, it becomes salicylic acid. This metabolite irreversibly inhibits the enzyme cyclooxygenase. Hence the the production of protective prostaglandins is blocked causing inflammation and pain.

What is the difference between a substance and mixture ?
snow_lady [41]

Explanation:

Matter can be categorized into substances and mixtures.

Matter is anything that has mass and occupies spaces.

Substances are distinct matter with the following properties:

  • All parts are the same throughout i.e homogeneous
  • Their composition is definite
  • They cannot be easily separated or broken down into simpler substances by physical means
  • Separation by physical means is not easy
  • They have a unique set of physical properties.

Mixtures have the following properties:

  • Their composition is indefinite i.e they consist of two or more elements and/or compounds in any proportion by mass
  • Their constituents retains their identity
  • They can easily be separated by physical means
  • They have a broad range of physical properties.

Need help with balancing equations
solniwko [45]

The balanced equation of the reaction shows that the mole of atoms on both sides of the reaction are equal.

<h3>What are balanced chemical equations?</h3>

Balanced chemical equations are equations in wgich the moles of each species on both sides of the reaction are equal.

To balance chemical equations, numerical coefficients are placed in front of the species in the reaction.

The balanced equations of the reaction are as follows:

3Pd + 4H_3PO_4 \rightarrow Pd_3(PO_4)_4 + 6H_2 \\

C_{11}H_{24} + 17O_2 \rightarrow 11CO_2 + 12H_2O \\

2Al(HCO_3)_3 + 3H_2SO_4\rightarrow Al_2(SO_4)_3 +6CO_2 +6H_2O \\

Therefore, the balanced equation of the reaction shows that the mole of atoms on both sides of the reaction are equal.
