Four: 2x2 = 4 C atoms in 2C2H4 (= two molecules C2H4)
Ethene (C2H4) has 2 bonds between the 2 carbon atoms and each carbon atom shares 2 electrons from 2 Hydrogen atoms.
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.
Carbon atoms can be bonded together.

They contain many carbon atoms
Ethene (C2H4) has 2 bonds between the 2 carbon atoms and each carbon atom shares 2 electrons from 2 Hydrogen atoms.
The answer is 15 carbon atoms.
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.

12 carbon atoms exist in a molecule of maltose if the molecules have 12 oxygen atoms.
Carbon atoms can be bonded together.
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).
there is no hydrogen in carbon dioxide. since carbon dioxide is CO2 there are 3 carbon and 6 oxygen atoms in three molecules.
12
The formula is CO2, so there is one atom of carbon and two atoms of oxygen in each molecule.So there are 2.5x10^21 atoms of carbon in that many molecules of CO2.
18 carbon atoms
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.
18 carbon atoms (6 in each)
