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.

What are the number of carbon atoms and oxygen atoms in 2 molecules of carbon dioxide?
Carbon dioxide: CO2. The number to the right of the symbol for an element indicates how many atoms of that element are present in single molecule. If there is no number then there is one atom present. Then in the case of carbon dioxide there must be one atom of carbon (C) and two atoms of oxygen (O). Double these to provide the numbers of atoms of the two elements in two molecules: two of carbon, four of oxygen.
Can you convert this to a word equation 2CO 2NO -- N2 2CO2?
carbon monoxide + nitrigen oxide --- nitrogen + carbon dioxide
How many total oxygen atoms 2CO2 and 3 H2O combined?
The appropriate rule is that for each element in the formula unit or molecular formula of a compound, the number of atoms of one element is the product of the subscript following the atomic symbol and the coefficient, a normally sized and placed number preceding the formula unit. If either or both of an explicit subscript or coefficient is missing, the number 1 is assumed. Therefore, 2CO2 contains 4 oxygen atoms and 3 H2O contains 3 oxygen atoms, for a total of 7 in the two formulas combined.
What is the balanced equation for nitrogen monoxide plus carbon monoxide equals nitrogen plus carbon dioxide?
The balanced equation for the reaction between nitrogen monoxide (NO) and carbon monoxide (CO) to form nitrogen (N2) and carbon dioxide (CO2) is: 2NO + 2CO -> N2 + 2CO2

What the big in 2CO2 mean?
'Big what???' 2CO2 The prefix '2' means two molar ratios. The 'C' is one atom of carbon The 'O' is oxxygen The suffix '2' , which should be written subscript, indicates that there are two atoms of oxygen.

How many oxygen atoms are there in the formula 2CO2?
There are 4 oxygen atoms in the formula 2CO2. Each CO2 molecule contains 2 oxygen atoms, so when you have 2 CO2 molecules, you get a total of 4 oxygen atoms.
Which new gas is formed when carbon monoxide is oxidised?
Carbon dioxide is formed when carbon monoxide is oxidized. Carbon monoxide reacts with oxygen in the air in the presence of a catalyst to produce carbon dioxide.
How many carbon dioxide molecules will be formed from two ethane molecules?
I am presuming that you are asking how many carbon dioxide (CO2) molecules will be formed when two ethane (C2H6) molecules burn in a plentiful supply of oxygen. The following balanced equation is that of the burning of ethane in a plentiful supply of oxygen: C2H6 + 3.5O2 -----> 2CO2 + 3H2O. The number before each of the molecules in the equation tells us how many there are in this reaction. This means that for every one ethane molecule that is burnt, two carbon dioxide molecules are produced.
How many total oxygen atoms 2CO2 and 3 H2O combined?
The appropriate rule is that for each element in the formula unit or molecular formula of a compound, the number of atoms of one element is the product of the subscript following the atomic symbol and the coefficient, a normally sized and placed number preceding the formula unit. If either or both of an explicit subscript or coefficient is missing, the number 1 is assumed. Therefore, 2CO2 contains 4 oxygen atoms and 3 H2O contains 3 oxygen atoms, for a total of 7 in the two formulas combined.
What is the balanced equation for hydrogen fluoride plus carbon dioxide?
4hf+2co2 --> 2h2o+2cf2
What is the balanced equation for nitrogen monoxide plus carbon monoxide equals nitrogen plus carbon dioxide?
The balanced equation for the reaction between nitrogen monoxide (NO) and carbon monoxide (CO) to form nitrogen (N2) and carbon dioxide (CO2) is: 2NO + 2CO -> N2 + 2CO2
What is the equation of carbon burning in a good supply of oxygen to form carbon dioxide?
The balanced equation for carbon burning in a good supply of oxygen to form carbon dioxide is: 2C + O2 -> 2CO2
How many elements are in a 2co2 atom?
A CO2 molecule consists of 3 atoms: 1 carbon atom and 2 oxygen atoms.
