How can balenced equations be used to calculate the volume of gases formed in chemical reactions?
Balanced equations show the molar ratios of reactants and products in a chemical reaction. Using the coefficients in a balanced equation, you can determine the moles of reactants consumed and products formed. Then, you can use the ideal gas law to calculate the volume of the gases formed, given the temperature, pressure, and moles of the gas.
How can you use a balanced chemical equation to write an equilibrium constant expression?
To write an equilibrium constant expression using a balanced chemical equation, you need to identify the reactants and products involved in the equilibrium and write the expression as a ratio of the products raised to their stoichiometric coefficients divided by the reactants raised to their stoichiometric coefficients. The general format is [products]/[reactants]. The coefficients from the balanced equation become the exponents in the expression.
What True about balancing chemical equations?
Balancing chemical equations involves ensuring that the number of atoms of each element is the same on both sides of the equation, using coefficients. This is important because it maintains the law of conservation of mass. Balancing equations allows us to predict the amounts of reactants needed and products formed in a chemical reaction.
Compare and contrast chemical and ionic equations?
Chemical equations represent chemical reactions using chemical formulas and symbols, while ionic equations specifically show the dissociation of ionic compounds into their constituent ions. Ionic equations focus on the ions involved in the reaction, whereas chemical equations show the reactants and products in their molecular form. Ionic equations are useful when studying reactions involving ions, while chemical equations provide a general overview of the reaction.
How do you use the word chemical equation in a sentence?
To correctly determine the balanced chemical equation, one must make sure that the products are appropriately relating to the reactants and make sure that the equation is balanced with the lowest coefficients.
How is the coefficient used to count the number of atoms in a substance?
The coefficient in a chemical formula represents the number of moles of each substance involved in a reaction. By using the coefficients in a balanced chemical equation, you can determine the ratio of atoms between the reactants and products, allowing you to calculate the number of atoms present in a substance.
Calculations using balanced equations are called?
Stoichiomeric calculations
How do scientists represent chemical reactions?
Scientists represent chemical reactions using chemical equations, where reactants are on the left side and products on the right side. The equation includes the chemical formulas of the substances involved and coefficients representing the mole ratios of reactants and products. Symbols like arrows indicate the direction of the reaction.
When solving stoichiometric problems how is the correct mole ratio expressed?
The correct mole ratio is expressed using coefficients from a balanced chemical equation. These coefficients represent the relative number of moles of each substance involved in the reaction. The mole ratio is determined by these coefficients and is used to convert between different substances in stoichiometric calculations.
True or false The key to using the elimination method is to find variable terms in the two equations that have equal or opposite coefficients?
True
What ratio can you determine using the coefficient in a chemical formula?
The ratio of different elements present in a compound can be determined using the subscripts or coefficients in a chemical formula. These coefficients represent the relative number of each type of atom in the compound.
What is the first step in balancing a chemical reaction?
Rules of balancing chemical equations:1. write the unbalanced equation2. count the number of atoms of the same element on reactant and product side of equation3. make the number of atoms the same by changing the coefficients, not subscripts4. balance hydrogen and oxygen last5. reduce coefficients if possibleThe first step in balancing a chemical equation is identifying all elements.For example:H2OSo the elements you would identify are H (hydrogen) and O (oxygen).--------------------------------------------------------------------------------------------------------b. identify the reactants and products. - (e2020)
