Question | Answer |
In a chemical reaction, the arrow points to the [...]. | In a chemical reaction, the arrow points to the products. |
In a chemical reaction, [...] are the numbers to the left of each reactant and product. | In a chemical reaction, coefficients are the numbers to the left of each reactant and product. |
In a chemical reaction, the [...] tells you how much of the entire reactant or product is used/produced. | In a chemical reaction, the coefficient tells you how much of the entire reactant or product is used/produced. |
The numbers in subscript tell you [...]. | The numbers in subscript tell you how many of the atom to their left is in the entire compound. |
When balancing chemical equations, never touch the [...] numbers! | When balancing chemical equations, never touch the subscript numbers! |
When balancing chemical equations, you can only touch the [...]! | When balancing chemical equations, you can only touch the coefficients! |
In a balanced chemical reaction, the number of moles of one thing (reactant or product) compared to the number of moles of another thing is a [...] ratio. | In a balanced chemical reaction, the number of moles of one thing (reactant or product) compared to the number of moles of another thing is a mole ratio. |
[...] ratios give you sort of an exchange rate: put in X reactants, get Y products. | Mole ratios give you sort of an exchange rate: put in X reactants, get Y products. |
Mole ratios are super easy to figure out; just look at the [...] in a balanced equation. | Mole ratios are super easy to figure out; just look at the coefficients in a balanced equation. |
You find the exchange rate (mole ratio) between reactants and products by looking at the [...]. | You find the exchange rate (mole ratio) between reactants and products by looking at the balanced equation. |
The [...] reactant/reagent is the one you run out of first. | The limiting reactant/reagent is the one you run out of first. |
[...] is basically figuring out how much product you can get for a certain amount of reactant. | Stoichiometry is basically figuring out how much product you can get for a certain amount of reactant. |
The first step in any Stoichiometry problem is usually converting everything to [...]. | The first step in any Stoichiometry problem is usually converting everything to moles. |
We always use moles in stoichiometry because the [...] tells us how many moles of each reactant and product are involved. | We always use moles in stoichiometry because the balanced equation tells us how many moles of each reactant and product are involved. |
[...] can tell you how much product you can make with a known amount of reactants, or how much reactant you'll need for a certain amount of product. | Stoichiometry can tell you how much product you can make with a known amount of reactants, or how much reactant you'll need for a certain amount of product. |
