What tells you how many atoms or molecules of a reactant or a product take part in a reaction?

The coefficients in front of the reactants and products tell you how many atoms or molecules take part in a reaction. For example, the chemical equation 2 H2 plus O2 produces 2 H2O means that two hydrogen atoms react with one oxygen atom to produce two water molecules.

How many oxygen atoms are in the reactant aluminum phosphate in the balanced reaction below?
there are 8
What is a chemical reactant in a chemical reaction?
A reactant is the starting material of a reaction. For example, in the reaction 2H(+) + O(2-) --> H2O, both H(+) ions and the O(-) ion are the reactants, whereas H2O is the product of the reaction. A reactant is something that REACTS.
How does decreasing reactant concentration affect the rate of reaction?
It reduces it. This is because when reactions occur the atoms 'bump into' each other. The less atoms per space (decreased concentration) the less bumping in a given period takes place, therefore creating a slower reaction.
What is never gained or lost in a chemical reaction?
Matter is never lost or gained in a chemical reaction. A chemical reaction cannot destroy or create atoms, it merely rearranges how they are connected and arranged in new molecules. While the atoms rearrange, energy is released (such as through light, fire or heat), or absorbed, (such as when plants use sunlight to make sugar out of carbon and water). Some atoms may evaporate, making the resulting product seem lighter or smaller, such as when coal or wood burns, but the atoms themselves are not destroyed.
What happens during a chemical reaction?
Electrons in atoms and molecules, etcare rearranged. This results in chemical bonds forming or being broken and thus new substances being formed.Electronsare rearranged.
In a chemical reaction what tells you how many atoms or molecules of a reactant or a product take part in a reaction?
A subscript
How are reactant atoms and molecules similar to their product atoms and molecules?
The numbers of atoms with the same atomic number are the same in both reactants and products in any chemical reaction.
Does an equation indicates the number of atoms of each product and each reactant involved in a reaction?
Not quite. A properly balanced an equation indicates the number of atoms of any elemental product and any elementalreactant involved in a reaction, along with the number of molecules of any molecular compound product and any molecular compound reactant involved in the reaction. The original sentence is deficient because in any chemical reaction, there must be at least one non-elemental product or reactant.
When two reactant molecules or atoms interact the product will have?
No new properties
What does a coefficients tell you?
That would depend on the coefficient in question. ------------------------------------------------------------------------------A coefficient indicates how many molecules or atoms of each reactant & product are involved in a reaction. -<3
What chemical equation has equal numbers of reactant and product atoms?
Any chemical reaction.
What is a coefficient in science?
a coefficent in physical science means:a number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product that are involved in a reaction
In achemical equation what tells you how many atoms or molecules of a reactant or a product take part in a reactin?
A subscript?
The number in front of a chemical formula that tells how many molecules or atoms of each reactant take part in a reaction called?
subscript
How do you use the words chemical reactant and product in a sentence?
Chemical: Vinegar contains the chemical, Acetic acid. Reactant: The limiting reactant weight was used to calculate the percentage yield of the product. Product: The product was nearly pure from just washing alone, following the reaction.
What happens to the atoms in a displacement reaction?
Atoms in either a single or double displacement reaction are simply rearranged to form new substances. They're the same atoms on the reactant side as the product side, which upholds the law of conservation of mass.
Is CaCO3 a reactant or product?
CaCO3, calcium carbonate can be either a reactant or a product. If it comes at the beginning of a reaction, then it is a reactant. If it comes at the end of the reaction, then it is a product.
