FW of O2 is FW of CO2 is Therefore the limiting reactant must be C6 H6. Wood burns 2. Plants decompose in a compost pile. Food is digested in the stomach. Ice melts correct 5. Iron rusts Explanation: A physical change occurs with no change in chemical composition. Melting involves no change in composition, only a phase change.
H2 O 41 grams of C6 H6 are allowed to react with How much CO2 will be produced by this reaction? Correct answer: None of these 2. Explanation: The two hydrogen atoms and one oxygen atom making water exemplies two or more atoms bonded together to make a molecule.
None of these Explanation: mg refers to Explanation: The mole concept is important in chemistry because we know that if we weight The correct answer is not given.

Determine the number of moles of C in 0. Figure A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
That gives the number of moles of each element. The one that gives the greatest number of moles has the greatest number of atoms. The answer is We assume you are converting between grams Aluminum and mole. You can view more details on each measurement unit: molecular weight of Aluminum or mol The molecular formula for Aluminum is Al.
One sulfuric H2SO4 molecule has 2 hydrogen atoms , 1 sulfur atom, and 4 oxygen atoms. You can also say one mole of sulfuric acid has two mols of hydrogen atoms , 1 mol of sulfur atoms , and 4 moles of oxygen atoms. So in total, we have 7 mols of atoms. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms.
How many atoms are there in 3. Category: science chemistry. If you have a compound like H 2 O, then: one mole of water contains 6. How many moles are in 5. How many moles are in 2. How many moles are present in 36 gram of water? How many formula units of NaCl are in a mole of nacl? How do I calculate moles? How many atoms are in h2o? How many moles are in 15 grams of lithium? Approx 52 moles.
