Consider the balanced equation for the following reaction:

Zanzabum

<u>Answer:</u> The amount of carbon dioxide formed in the reaction is 5.663 grams

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

Given mass of oxygen gas = 8 g

Molar mass of oxygen gas = 32 g/mol

Putting values in equation 1, we get:

$\text{Moles of oxygen gas}=\frac{8g}{32g/mol}=0.25mol$

For the given chemical equation:

$7O_2(g)+2C_2H_6(g)\rightarrow 4CO_2(g)+6H_2O(l)$

By Stoichiometry of the reaction:

7 moles of oxygen gas produces 4 moles of carbon dioxide

So, 0.25 moles of oxygen gas will produce = $\frac{4}{7}\times 0.25=0.143mol$ of carbon dioxide

Now, calculating the mass of carbon dioxide from equation 1, we get:

Molar mass of carbon dioxide = 44 g/mol

Moles of carbon dioxide = 0.143 moles

Putting values in equation 1, we get:

$0.143mol=\frac{\text{Mass of carbon dioxide}}{44g/mol}\\\\\text{Mass of carbon dioxide}=(0.143mol\times 44g/mol)=6.292g$

To calculate the experimental yield of carbon dioxide, we use the equation:

$\%\text{ yield}=\frac{\text{Experimental yield}}{\text{Theoretical yield}}\times 100$

Percentage yield of carbon dioxide = 90 %

Theoretical yield of carbon dioxide = 6.292 g

Putting values in above equation, we get:

$90=\frac{\text{Experimental yield of carbon dioxide}}{6.292g}\times 100\\\\\text{Experimental yield of carbon dioxide}=\frac{90\times 6.292}{100}=5.663g$

Hence, the amount of carbon dioxide formed in the reaction is 5.663 grams

What is the density of a piece of wood that has a mass of 35.0 grams and a volume of 26.4 cm3

vladimir2022 [97]

Answer:

We have the final answer as

Explanation:

The density of a substance can be found by using the formula

<h3> $density = \frac{mass}{volume}$ </h3>

From the question

mass = 35 g

volume = 26.4 cm³

The density of the wood is

$density = \frac{35}{26.4} \\ 1.325757575757...$

We have the final answer as

Hope this helps you

Answer:

Oxygen atoms form two double bonds in silicon(IV) oxide.

Silicon(IV) oxide has a high melting point.

Explanation:

Silicon dioxide is structurally analogous to carbon dioxide in the sense that it also contains two oxygen atoms that are double bonded to silicon the central atom in the molecule.

Silicon dioxide has a very high melting point of about 1710 degrees centigrade because of its large macromolecular structure which requires much energy to break such intermolecular interactions.
