How many types of bonds are present ethene?

Ethene (C2H4) has 2 bonds between the 2 carbon atoms and each carbon atom shares 2 electrons from 2 Hydrogen atoms.


How do you distinguish between ethane and ethene?

Ethane has two carbon atoms and six hydrogen atoms (C2H6). It is a flammable gas and is a saturated molecule, meaning that each carbon atom has four bonds linked to 4 other atoms. Methane (CH4), propane (C3H8) and butane (C4H10) are similar molecules and all are flammable gases. Ethene has two carbon atoms and four hydrogen atoms (C2H4). It is also a gas but it is an unsaturated molecule: the two carbon atoms are linked by a double bond. Ethene molecules can join together into a single, long molecule. The result is a string of carbon atoms that each have two hydrogen atoms attached and are also linked to two other carbon atoms. This is polythene or polyethelene, a simple polymer that is used for plastic bags among other things. The ability to form into long chains is due to the double bond between the carbon atoms in the ethene molecule.


What is special about carbon atoms that they can make so many kinds of molecules?

Carbon atoms can be bonded together.


How many atoms of carbon are in 3c2h4?

In the chemical formula (3 \text{C}_2\text{H}_4), there are 3 molecules of ethene ((\text{C}_2\text{H}_4)). Each molecule contains 2 carbon atoms, so the total number of carbon atoms is (3 \times 2 = 6). Therefore, there are 6 atoms of carbon in (3 \text{C}_2\text{H}_4).


When the carbon atoms in hydrocarbon molecules are bonded to as many hydrogen atoms as possible is an unsaturated hydrocarbon is produced?

No, when the carbon atoms in hydrocarbon molecules are bonded to as many hydrogen atoms as possible, a saturated hydrocarbon is produced. Unsaturated hydrocarbons have carbon-carbon double or triple bonds, resulting in fewer hydrogen atoms bonded to the carbon atoms.

How many hydrogen and carbon atoms are made in 5 molecules of carbon dioxide?

5 molecules of carbon dioxide will contain 5 carbon atoms (1 per molecule) and no hydrogen atoms as carbon dioxide contains only carbon and oxygen. The 5 molecules will contain a total of 10 oxygen atoms (2 per molecule).

How many carbon atoms does it take to create three glucose molecules?

To create three glucose molecules, it would require a total of 72 carbon atoms because each glucose molecule contains 6 carbon atoms. So, 6 carbon atoms x 3 glucose molecules = 18 carbon atoms for each individual glucose molecule, and 18 carbon atoms x 3 = 72 carbon atoms in total.


In two molecules of carbon dioxide 2CO2 there are how many atoms and what are they made of?

2 CO2 means there are two molecules of carbon dioxide. In one molecule of CO2 there is 1 carbon atom, and 2 oxygen atoms. So three atoms total. Therefore, in 2 molecules (each with 3 atoms) there are 6 atoms total. The molecules are made of atoms of carbon and oxygen. The atoms themselves are made of protons, electrons, and neutrons.

How many atoms in 2 molecules of carbon dioxide?

There are a total of 6 atoms in 2 molecules of carbon dioxide. Each molecule of carbon dioxide contains 1 carbon atom and 2 oxygen atoms. Therefore, in 2 molecules, you would have 2 carbon atoms and 4 oxygen atoms, totaling 6 atoms.
