What is the difference between a chemical reaction and a product in a chemical equation?
The reactants are the substances that undergo the chemical reaction, and are shown on the left side of a chemical equation. The products are produced by the chemical reaction, and are shown on the right side of the chemical equation.
Define law of mass action?
Law of Mass Action states that rate of a reaction is directly proportional to the product of concentration of reactant with each concentration raised to the power equal to its respective stoichiometric coefficient as represented by the balanced chemical equation. It is also called the law of chemical equilibrium.
Why do scientists balance chemical equations?
Chemical formulas are succinct, unambiguous, and transcend language. Writing the same thing in words would take much longer and would only be understood by those who spoke the same language as the writer.
What are the importance of putting a chemical equation into words?
Putting a chemical equation into words helps to describe the reactants, products, and the chemical reaction that is occurring. It allows for easier communication of the reaction process and helps in understanding the stoichiometry involved. Additionally, writing chemical equations in words helps to identify the type of reaction taking place.
why do Chemical equations use symbols instead of words to summarise chemical reactions?
To understand the coupling and decoupling of compounds in transit based on chemical reaction.
How are the words reactant product chemical reaction and catalyst related?
Reactants: the initial substances in a chemical reaction Products: the final substances in a chemical reaction Catalyst: a stimulator of a chemical reaction, not directly involved in the reaction, remain unchanged
What is the term for a substance undergoing a chemical change?
The other term for a chemical change is a chemical reaction. They both refer to a reaction between different components chemically to make a product that is different from them in terms of chemical structure.
A sentence with the words product and production in the same sentence?
Production of our new product will begin next week.
How do you calculate theoretical yield?
When calculating the theoretical yield of a product within a reaction, the idea is to convert mass reactant --> mass product; in other words, "how many grams of product X will N grams reactant A and N grams reactant B yield (create)?" Whichever mass is the lowest is considered the theoretical yield (in other words, the reactant that produces the least amount of product).__A + __B --> __Xmass reactant A => mass product X (mass A: mass X)mass reactant B => mass product X (mass B: mass X)In order to calculate the theoretical yield, you need to convert the mass of reactant A to the mass of product X AND the mass of reactant B to the mass of product X.1. Multiply the mass of the reactant by the number of molecules (or moles) X and by the molar mass of X.2. Divide the above by the molar mass of reactant (which is multiplied by the number of molecules [or moles] of reactant).Do this for each reactant involved.- FormulaMass reactant * # molecules (moles) product X1 * molar mass product X--------- # molecules (moles) reactant * molar mass reactant= Mass Product X- Conversion FactorMass reactant * 1 mol reactant * # molecules product X * molar mass product X-------------- molar mass reactant - # molecules reactant --- 1 mol product X= Mass Product X1the # molecules is obtained from the balanced equation. For clarification, I stated # molecules in place of mol; however, on practice problems and in textbook tutorials on how to solve problems in regards to stoichiometry, it is likely it will say mol or moles instead of # molecules.Ex. Ca(NO3)2 + 2NaF --> CaF2 + 2NaNO3What is the theoretical yield of CaF2 (product X) when 43.5g Ca(NO3)2 (reactant A) react with 39.5g NaF (reactant B)?43.5g Ca(NO3)2 * 1 mol Ca(NO3)2 * 1 molecule1 CaF2 * 78.08g CaF2-------------- 164.1g Ca(NO3)2 ----- 1 molecule1 Ca(NO3)2 - 1 mol NaF= 22.3g CaF236.5g NaF * 1 mol NaF * 1 molecule1 CaF2 * 78.08g CaF2------------ 41.99g NaF --- 2 molecules1 NaF --- 1 mol CaF2= 36.7g CaF2The theoretical yield of CaF2 is 22.3g, as it is the lowest amount of product created. In this case, the limiting reagent (the reactant that produced the least product) is Ca(NO3)2 and the reagent in excess is NaF."A chain is only as strong as its weakest link".
What is a simple sentence using the word chemical formula?
This is a simple sentence using the words "chemical formula".
What are 5 key words in a chemical change?
Reactants: Substances that are present before a chemical reaction occurs. Products: Substances that are produced as a result of a chemical reaction. Chemical reaction: Process where reactants are transformed into products, often involving the breaking and forming of chemical bonds. Energy: May be absorbed or released during chemical reactions, impacting the reaction's outcome. Catalyst: Substance that speeds up a chemical reaction without being consumed in the process.
How are word equations organized?
-The left side of the equation list all the reactants -The right side of the equation list all the products -An arrow points from the reactants to the products. It shows that something is produced during the reaction. All the reactants and all the products in a word equation are separated by a plus sign (+) reactant 1+reactant 2 ---> product 1 product 2
How do you use the words chemical reaction and precipitate in a sentence?
In a chemical reaction, a precipitate is an insoluable solid that emerges from a liquid solution.
