In two molecules of carbon dioxide 2CO2 there are how many atoms and what are they made of?
Keeleyt
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?
One molecule of CO2 has one carbon atom and two oxygen toms. denoted by the formula CO2 So in two molecules of CO2 there are CO2 & another CO2 . Chemically this is shown as 2CO2, that is a figure is placed to the left of the molecular formula. Since there are CO2 & another CO2 , then there are two(2) atoms of carbon and four(4) atoms of oxygen.
Can you convert this to a word equation 2CO 2NO -- N2 2CO2?
carbon monoxide + nitrigen oxide --- nitrogen + carbon dioxide
What is the balanced equation for nitrogen monoxide plus carbon monoxide equals nitrogen plus carbon dioxide?
2co + 2no -> 2co2 + n2
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.
In combustion is carbon dioxide and carbon monoxide formed always formed?
The combution process is two stage, carbon monoxide is formed first and if excess oxygen is present an the carbon monoxide reacts with additional oxygen to form carbon dioxide. 2C + O2 ---> 2CO + O2 ---> 2CO2

two carbon atoms and two oxygen atoms present
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.

What gas is produced when yeast respire anaerobically?
When yeast respires anaerobically it takes glucose (C6H12O6) and breaks it into ethanol, a small amount of energy, and two molecules of carbon dioxide gas (2CO2).
