Phosphine, an extremely poisonous and highly reactive gas, will react with oxygen to form tetraphosphorus decoxide and water, as

erica [24]

<u>Answer:</u> The amount of $P_4O_{10}$ formed is 469.8 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 phosphine = 225 g

Molar mass of phosphine = 34 g/mol

Putting values in equation 1, we get:

$\text{Moles of phosphine}=\frac{225g}{34g/mol}=6.62mol$

The given chemical reaction follows:

$4PH_3(g)+8O_2(g)\rightarrow P_4O_{10}(s)+6H_2O(g)$

Assuming that oxygen gas is present in excess, it is considered as an excess reagent.

Phosphine is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

4 moles of phosphine produces 1 mole of $P_4O_{10}$

So, 6.62 moles of phosphine will produce = $\frac{1}{4}\times 6.62=1.655mol$ of $P_4O_{10}$

Now, calculating the mass of $P_4O_{10}$ by using equation 1:

Molar mass of $P_4O_{10}$ = 283.9 g/mol

Moles of $P_4O_{10}$ = 1.655 moles

Putting values in equation 1, we get:

$1.655mol=\frac{\text{Mass of }P_4O_{10}}{283.9g/mol}\\\\\text{Mass of }P_4O_{10}=(1.655mol\times 283.9g/mol)=469.8g$

Hence, the amount of $P_4O_{10}$ formed is 469.8 grams.

Explain how carbon’s bonding ability makes it unique.

STatiana [176]

$\huge\fcolorbox{red}{pink}{Answer ♥}$

The carbon atom is unique among elements in its tendency to form extensive networks of covalent bonds not only with other elements but also with itself. ... Moreover, of all the elements in the second row, carbon has the maximum number of outer shell electrons (four) capable of forming covalent bonds.

Hope it helps uh ✌️✌️✌️

Students are attempting to demonstrate a reaction of liquid water separating into hydrogen and oxygen gases:

AlexFokin [52]

Answer:

Explanation:

When water separates into hydrogen and oxygen gas, a decomposition reaction is taking place (one substance breaking apart or breaking down into two or more substances).

The law of conservation of mass tells us that mass is not created or destroyed during a chemical reaction, so the total mass will remain the same. This is supported by the diagram on the page, which shows that in the reactants, there are four hydrogen atoms and two oxygen atoms, and this amount is the same on the product side.

What is the difference between inert and stable?

Katena32 [7]

Inert means that the substance did not have a tendency to react at all, while stable means that the substance has reached a chemical state in which it is not likely to react. Stability is easier to overcome than inertness.
