What is the atomic number for carbon dioxide?
Carbon Monoxide is a compound with symbols of CO compounds do not have atomic numbers. Carbon is an element with the atomic number 6 oxygen is an element with the atomic number 8
Whats the atomic number for dry ice?
The atomic number for dry ice, or solid CO2, is 44. An atomic number is just the total number of protons for a given atom, or in this case, a given molecule. Atomic number refers to a singular element. e.g. What is the atomic number for copper, zinc, helium, etc.? The mass of a compound, however, would be called molecular mass, the added atomic masses in the compound.
The number of a known compound?
The number of a chemical compound is given after the rules of American Chemical Society (CA number).
What is the prercent by mass of hydrogen in NH3?
The formula shows that there are three times as many atoms of hydrogen as of nitrogen in the compound. The gram atomic masses are 1.00794 for hydrogen and 14.0067 for nitrogen. Therefore, the percent by mass of hydrogen in the compound is 100{[3(1.00794)]/[3(1.00794) + 14.0067] or 17.7553 %, to the justified number of significant digits.
How do atomic numbers and atomic masses increase in the periodic table?
The atomic number and atomic masses increase as you move from left to right.

What is the atomic number for carbondioxide?
Carbon dioxide is a compound, not an element. It does not have an atomic number.
Is carbon dioxde a compound?
Yes, Carbon Dioxide is a Compound its symbol is CO2 (Note Number is meant to be small)
What is the compound of bo2?
The elements are boron and oxygen. The number of atoms is 3.
What did amedeo avogadro?
He published a paper called (translation) "Essay on determination the relative masses of the elementary molecules of bodies and the proportions by which they enter these combinations". It is from his work that we get 'Avogadro's Number' the number of molecules/atoms in a mole.

What is the atomic number of quartz?
Quartz is a compound, specifically silicon dioxide, and compounds do not have atomic numbers; only atoms do.
How many molecules are in3.0 moles of carbon dioxide?
The number of molecules in a mole of any covalently bonded compound such as carbon dioxide is always Avogadro's Number. Therefore, the number of molecules in 3.0 moles is 1.8 X 1024, to the justified number of significant digits.
Is air a compound or element or mixtures?
It is a mixture MAINLY of elements- nitrogen, oxygen, argon. However, there are a small number of compounds in the mixture- such as carbon dioxide (compound of carbon and oxygen)
What is the atomic number for carbon dioxide?
Carbon Monoxide is a compound with symbols of CO compounds do not have atomic numbers. Carbon is an element with the atomic number 6 oxygen is an element with the atomic number 8
Is carbon dioxide heavier than air explanation?
Carbon dioxide's chemical formulae is CO2, and waters chemical formulae is H2O. If you look at the periodic table you will find a number called the mass number. This is the mass of that particular element. To find the mass of a compound such as carbon dioxide or water you simple add up the mass numbers of each individual element within that compound. So for CO2 you add 12(for carbon,C) and 16(for oxygen,O) and again another 16 (for the 2nd oxygen) you get 44 for the total mass of carbon dioxide. If you now do the same for water adding 1, 1 and 16 you get a total mass number of 18. 44 is higher than 18 therefore carbon dioxide is the heavier compound
How many moles of carbon dioxide are in 418 grams of the compound?
The gram molecular mass of carbon dioxide is 44.01. Therefore, 418 grams contains 418/44.01 or 9.50 moles, to the justified number of significant digits.
