What is the number of carbon atoms in 2.5 x 1021 molecules of carbon dioxide?
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.
What does the subscript 2 mean in the chemical formula CO2?
it means there are 2 molecules of O (oxygen) in the compound CO2
How many moles of c are in 000831 moles of co2?
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
Which has the largest number of molecules O2 CO2 or NH3?
What is listed are all examples of just onemolecule. O2 is one molecule of oxygen, CO2 is one molecule of carbon dioxide, and NH3 is one molecule of ammonia. Perhaps you're asking which has the largest number of atoms? In that case, the answer is ammonia, with a total of four atoms.
What is the balanced chemical equation for CaCO3 to CaO plus CO2?
The equation is already balanced:CaCO3(s) --> CaO(s) + CO2(g)ExplanationA balanced chemical equation is one where the number of atoms on both sides are equal. Chemical equations must be balanced because there is only a rearrangement of atoms in a reaction so the number of atoms you start off with must be the same as the number of atoms you end up with.If we take a look at the equation, we can see that there is 1 calcium atom, 1 carbon atom and 3 oxygen atoms present on both sides. As the number of these atoms on both sides are equal, the equation is balanced.
How many atoms is 110 grams of CO2?
After figuring out the calculations using the weight of CO2 and Avogadro's number, the total number of atoms in 110 grams of CO2 is 2.34 X 10^18 in sum.
Determine the number of oxygen atoms present in 25.0g carbon dioxide?
Carbon Dioxide-CO2 To get molecules, we must convert grams to moles and moles to atoms using Avogadro's number. Molar mass of CO2= C:12.0g+O:16.0gx2=44.0g CO2 25.0g CO2 | 1 mol CO2 | 6.02x10 23 molecules CO2 ------------------------------------------------------------------- = 3.42x10 23 molecules CO2 1 | 44.0g CO2 | 1 mol CO2 Now to get the number of oxygen atoms. Since there are 3 atoms in CO2 and 2 of them are oxygen, we will divide by 3 (1.14x10 23) and multiply by 2 (2.28 x10 23) So the number of oxygen atoms in 25.0 grams of CO2 is 2.28x10 23 or 228 000 000 000 000 000 000 000
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.
What is the number of atom in carbon dioxide?
There are 2 atoms in CO2. These are carbon and oxygen.
How many atoms are in 5.58 mol of CO2?
In one (1) molecule CO2 there are 3 atoms ( 1 C-atom and 2 O-atoms), so in 5 molecules CO2 (5CO2) there are 5 x 3 (= 15) atoms. Thus fifteenis the answer to you.
What is the number two called in the formula 8 CO2?
There are two atoms of oxygen in the molecule. One of carbon and two of oxygen to get CO2.
What is the number of carbon atoms in 2.5 x 1021 molecules of carbon dioxide?
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.
What is the total number of oxygen and hydrogen atoms in the product ch4 plus 2o2 -- co2 plus 2h2o?
4 ox atoms ... 4 h atoms
How many atoms in 6CO2?
no. of atoms = no. of moles * avogadros no. no. of atoms = 6 * 6*1023 no. of atoms = 3.6*1024 (ans)
How many atoms of in a CO2 molecule?
2 atoms
Atoms in carbon dioxide?
Do you mean to ask what is the molecular structure of carbon dioxide? CO2, 1 carbon atom (proton number 12) + two oxygen atoms (proton number 16)
What does the subscript 2 mean in the chemical formula CO2?
it means there are 2 molecules of O (oxygen) in the compound CO2
