Reactions & Equations
chemical formula that doesn't use words to identify the reactants and the products
what is a skeleton equation?
the part of a equation must be equal on both sides to follow the law o conservation?
What are the numbers of atoms?
a whole number in front on reactants/products to help balance a chemical equation
what is a coefficient?
In the reaction between iron and oxygen, the coefficients in the balanced equation tell you the relationship between reactants and products.
What is a Mole Ratio?
1)write a skeleton equation
2)count atoms on both sides (reactants/products)
3)add/adjust coefficients (reactants and products must equal)
4)reduce coefficients to lowest possible ration
5) check work
what are the steps to balance a equation?
In the equation for forming iron (III) oxide, element reacts with oxygen gas to produce the compound.
What is iron(Fe)?
Balance the following:
Al(s)+Br2(g) -->AlBr3
2Al(s)+3Br2(g) -->2AlBr3
If the balanced equation forming iron (III) oxide is
4Fe+3O^2-----> 2Fe^2O^3
This number of moles of oxygen gas reacts with 4 moles of iron.
What is 3 moles of O^3
Balance the following:
NaOH(aq)+CaBr2(aq)-->Ca(OH)2(s)+NaBr(aq)
2NaOH(aq)+CaBr2(aq)-->Ca(OH)2(s)+2NaBr(aq)
Using the balanced equation
4Fe+3O^2------>2Fe^2O^3
This is the number of moles of iron (III) oxide produced when 12 moles of Iron reacts compleatly
What is 6 Moles of Fe2O3?
