g Gaseous methane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 0.96 g of methane
galben [10]

Answer: 2.64 g of carbon dioxide that could be produced by the chemical reaction.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} CH_4=\frac{0.96g}{16g/mol}=0.06moles

\text{Moles of} O_2=\frac{6.37}{32}=0.20moles

CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)

According to stoichiometry :

1 mole of CH_4 require = 2 moles of O_2

Thus 0.06 moles of CH_4 will require=\frac{2}{1}\times 0.06=0.12moles  of O_2

Thus CH_4 is the limiting reagent as it limits the formation of product and O_2 is the excess reagent.

As 1 moles of CH_4 give = 1 mole of CO_2

Thus 0.06 moles of CH_4 give =\frac{1}{1}\times 0.06=0.06moles  of CO_2

Mass of CO_2=moles\times {\text {Molar mass}}=0.06moles\times 44g/mol=2.64g

Thus 2.64 g of carbon dioxide that could be produced by the chemical reaction.

What are the 5 parts of an atom?
saul85 [17]
N the nucleus, there are protons and neutrons. That's two parts. 

<span>Outside the nucleus, there are electrons. That's a total of three parts and that is all that chemists discuss. Theoretical physicists talk about other sub nuclear "parts", but if you include them, the number goes way over 5. </span>

<span>The "shells", "sub-shells", "orbits", "orbitals", "probabilities" and the like are not physical parts, but only descriptions of energy</span>

1. An atom of an elephant has atomic mass of 39 and has number of neutrons as 20 calculate protons number.
r-ruslan [8.4K]

Answer:

See Explanation

Explanation:

1) Let us recall that;

Mass number = number of protons + number of neutrons

Where;

Number of protons = ?

Number of neutrons =20

Mass number =39

Number of protons = mass number - number of neutrons

Mass of protons =39 - 20= 19 protons

2) Atomic number = 13

Number of neutrons =14

Then the mass number =13 +14 =27

The symbol of the element is 27X13

The number of protons= the number of electrons =13

The atomic number is the same as the proton number =13
