Oxygen because it is on the left of the periodic table so it has a strong pull.

Answer:

Oxygen atom will strongly attract the shared pair of electrons towards itself.

Explanation:

The bond formed between magnesium and oxygen atom is an ionic bond.In this type of chemical bond transfer of electrons takes place from one atom to another.

Electronegativity : tendency to attract shared purr of electrons towards itself.

The transfer of electrons from one atom to another type of an atom depends upon the electronegativities of the atoms.

  • Higher the electronegative character in an atom more will be the tendency of that atom to attract the electrons towards itself and form electronegative ion.
  • Lower the electronegative character ,more easily it will donate its electrons and  form a electropositive ion.

Out of magnesium and oxygen, oxygen is a second most electronegative element in a periodic table which means it will easily attract the shared pairs of electrons towards it self.

If the reaction of 150. G of ammonia with 150. G of oxygen gas yields 87. G of nitric oxide (no), what is the percent yield of t
Gekata [30.6K]

The percentage yield of the given reaction is 77.33%.

What is percentage yield?
Reactants
frequently produce fewer product quantities than predicted by the chemical reaction's formula. The percentage of a theoretical yield that's been produced in a reaction is calculated using the percent yield formula. Working through a stoichiometry problem yields the theoretical yield, which is the ideal quantity of the final product. The actual yield is determined by calculating the volume of the product formed. We can determine the percentage yield by dividing the actual yield by the theoretical yield.

Moles is calculated by using the formula:
Moles of Ammonia:
Given mass of ammonia = 150g
Molar mass of ammonia = 17 g/mol
Putting values in above equation, we get:

Moles of Oxygen
Given mass of oxygen = 150g
Molar mass of oxygen = 32 g/mol
Putting values in above equation, we get:
For the given chemical equation:

By Stoichiometry,
5 moles of oxygen reacts with 4 moles of ammonia.
So, 4.6875 moles of oxygen will react with =  of ammonia
As, moles of ammonia required is less than the calculated moles. Hence, ammonia is present in excess and is termed as excess reagent.
Therefore, oxygen is considered as a limiting reagent because it limits the formation of products.

By Stoichiometry of the given reaction:
5 moles of oxygen gas produces 4 moles of nitric oxide
So, 4.6875 moles of oxygen gas will produce =  of nitric oxide

Now, to calculate the theoretical amount of nitric oxide, we use equation 1: Molar mass of nitric oxide = 30 g/mol
 Given mass of nitric oxide = 112.5 g
Now, to calculate the percentage yield, we use the formula:
Experimental yield = 87 g
Theoretical yield = 112.5 g
Putting values in above equation, we get:
Hence, the percentage yield of the given reaction is 77.33%.

Compared with the energy it takes to separate oxygen and hydrogen from water, how much energy is released when they recombine?.
katrin2010 [14]

The same amount of energy released when they recombine

Yes, the energy required to separate water into O2 and H2 is at least equal to the energy released when these gases come together to form water.

<h3>What is the process for separating water into it's constituents ?</h3>

The process of separating water into hydrogen and oxygen is known as electrolysis. This reaction occurs in a device known as an electrolyzer.

  • This is around 260 kJ per mole of water, or just under 5 eV per water molecule (4 electrons times 1.23 V). One litre of water would require at least 16 MJ (4.4 kWh) in order to be split, which is more energy than would be required to send one litre of water into deep space.

How many liters of CO2 are in 4.76 moles? (at STP)
dem82 [27]

<u>Answer:</u> The volume of carbon dioxide gas at STP for given amount is 106.624 L

<u>Explanation:</u>

We are given:

Moles of carbon dioxide = 4.76 moles

<u>At STP:</u>

1 mole of a gas occupies a volume of 22.4 Liters

So, for 4.76 moles of carbon dioxide gas will occupy a volume of = \frac{22.4L}{1mol\times 4.76mol=106.624L

Hence, the volume of carbon dioxide gas at STP for given amount is 106.624 L
