Explain what a coefficient in a balanced chemical equation represents?
The coefficients in a chemical equation represent the amount of moles of each substance involved in the reaction. On a smaller level, it also represents the amount of particles that have to collide or are produced in the reaction. Consider the following example: CH4(g) + 2O2(g) (arrow) 2H2O(l) + CO2(g) The coefficent behind oxygen in the reactants means that 2 molecules of oxygen have to collide with 1 molecules of methane to react. The coefficients in the products mean that this reaction produces 2 molecules of water and 1 molecule of carbon dioxide.
What is the oxidation number for 5O2?
Atomic oxygen has oxidation number 0. Molecular oxygen also has 0 as oxidation number. It would be the same for five oxygen molecules as well.
How many oxygen molecules O2 are in 2.56 grams of O2?
The number of oxygen atoms is 0,188.10e23.
Avogadro's number 6.02 x 10²³ refers to?
how many atoms, molecules and ions are present in one mole of a substance
What is heavier Hydrogen gas or oxygen gas How do you know?
Oxygen is heavier as it has a mass number of 16 whereas hydrogen has a mass number of 1. Both form diatomic molecules (molecules of two atoms) making the formula masses 32 for oxygen and 2 for hydrogen.
What do the numbers 2 and 3 represent in the formula 2AgNO3 and in the equation?
2 represents two molecules of silver nitrate. 3 represents the number of oxygen atoms in each molecule of silver nitrate [or the number of oxygen atoms in the nitrate ion].
What represents oxygen's potential path as it cycles?
Plant releases oxygen. Oxygen molecules diffuse. Bear inhales.
What are the total number of atoms in two oxygen molecules?
There are 4 oxygen atoms in two oxygen molecules.
What does 2O 2 represent?
2O2 in a chemical reaction equation means that there are two moles of O2, or oxygen, molecules.
How many oxygen molecules are there in in 4 g of oxygen?
Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1) This tells us there is 0.125 mol of oxygen gas present. The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23) So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules
Who has higher number of molecules oxygen or ozone?
ozone
What does the term P50 mean?
The P50 represents the partial pressure at which the hemoglobin is 50% saturated with oxygen-that is, when there are two oxygen molecules on each hemoglobin molecule.
How many molecules are there in one mole of oxygen?
There is 1 Avagadro number - so, 6.022 x 1023 molecules in 1 mole of oxygen.
What is unusual about the number of oxygen molecules in some balanced hydrocarbon combustion?
Sometimes the coefficient for the oxygen molecule is not a whole number
