All organic molecules have what element in common

Chemistry
2 answers:
joja [24]3 years ago

Every organic molecules/compound contains carbon (c).

Some other very abundant are hydrogen, nitrogen, oxygen, phosphorus, and sulfur.

I learned this with the acronym CHNOPS.

C - Carbon

H - Hydrogen

N - Nitrogen

O - Oxygen

P - Phosphorus

S - Sulfur

Hope this helps!

<u>Answer:</u> The elements which are common for all organic molecules is hydrogen and carbon.

<u>Explanation:</u>

Another name for organic molecules are hydrocarbons. This means that the molecules which consist of hydrogen and carbon atoms is an organic compound.

For Example:

H_2O\text{ and }CO_2 are not organic compounds, because in water, carbon is not there and in carbon dioxide, hydrogen is not there. But, CH_4 is an organic compound because hydrogen and carbon both are present.

Hence, hydrogen and carbon elements are common to all organic molecules.

(40 Points) Complete, balance, compute the amounts of the products assuming 100% yield. 10g Na + 10g Oxygen.
Lilit [14]

13.5g

Explanation:

Given parameters:

Mass of Na = 10g

Mass of O₂ = 10g

Unknown:

Mass of products formed = ?

Balanced equation = ?

Solution:

The balanced chemical equation is shown below:

                  4Na       +     O₂     ⇒      2Na₂O

In any reaction, the specie in short supply determines the extent of the reaction.

This reaction is not an exclusion. We need to first determine the specie in short supply and use it to estimate the amount of product since we have a 100% yield which signifies that all was used up.

  let us convert to moles;

    Number of moles of Na = \frac{mass }{molar mass}  = \frac{10}{23} = 0.435mole

 Number of moles of O₂ = \frac{mass}{molar mass} = \frac{10}{32} = 0.313mole

From the given equation;

   4 moles of Na requires 1 mole of O₂;

  0.435 moles of Na will require \frac{0.435}{4} = 0.11 moles

 But the given amount O₂ is 0.313, this is an excess of 0.313 - 0.11 = 0.203moles

We see that Na is the limiting reagent;

   4 moles of Na gives 2 mole of Na₂O

   0.435 moles of Na will give \frac{0.435 x 2 }{4} = 0.22 moles

Mass of Na₂O = number of moles x molar mass = 62 x 0.22 = 13.5g
