Coefficients in a balanced chemical equation always can express the ratio of?
Moles of reactants and products thats wut i put on my test
Which quantity must always be the same on both sides of a balanced chemical equation?
The numbers of atoms of each elemental type, as represented by their element symbols, will always be the same on both sides of a balanced chemical equation.
Does there exist a quadratic equation whose coefficients are irrational but both the roots are rational?
None, if the coefficients of the quadratic are in their lowest form.
When you have a chemical change is the mass of what you start with less equal or greater than what you end with?
If the equation is balanced, the mass will be the same on each side of the equation. Matter cannot be created or destroyed.
What is the difference between a word equation a formula equation and a chamical equation?
A chemical formula is the way a particular chemical (element or compound) is represented using the letters given in the Periodic Table. For example, the chemical formula of oxygen is O2 and the chemical formula of caron dioxide is CO2A word equation describes a chemical reactionusing the names of chemicals only. For instance, the word equation for respiration is:glucose + oxygen => carbon dioxide + waterA formula equation also describes a chemical reaction, but uses chemical formulae instead of names and is balanced. An example of this would be methane burning in oxygen:CH4 + 2O2 => CO2 + 2H2O
What do coefficients in a chemical equation represent?
Coefficients in a chemical equation represent the number of units of the formula immediately following the coefficient that are involved in the balanced equation for the reaction.
What is a balanced chemical equation . why should chemical be balanced?
A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.
What information can you determine from the coefficients in this balanced chemical equation?
The coefficients in a balanced chemical equation represent the relative amounts of each substance involved in the reaction. They indicate the mole ratios of the reactants and products, which can be used to determine the stoichiometry of the reaction. The coefficients help to show the conservation of mass and atoms in the reaction.
How do the coefficients in a balanced equation compare quantites of two substances?
The coefficients in a balanced equation represent the relative number of moles of each substance involved in a chemical reaction. By comparing the coefficients of the substances in the balanced equation, you can determine the mole ratios between them. This allows you to calculate the amounts of substances consumed or produced in the reaction.
What is the relationship between coefficient and balance chemical equation?
Coefficients in a balanced chemical equation represent the relative amounts of reactants and products involved in a chemical reaction. By adjusting the coefficients, the equation can be balanced to ensure that the law of conservation of mass is upheld, meaning that the total number of atoms of each element are the same on both sides of the equation.
Are coefficients equal in a balanced chemical equation?
No, coefficients in a balanced chemical equation represent the relative amounts of each reactant and product involved in the reaction. Coefficients can be different for each substance in the equation based on the stoichiometry of the reaction.
What is the molar ratio of two reactants determined by?
The molar ratio of two reactants in a chemical reaction is determined by the coefficients of the balanced chemical equation. These coefficients represent the number of moles of each reactant that are involved in the reaction. The molar ratio is the ratio of these coefficients.
Is it true that the subscripts in a balanced chemical equation specify the volume ratios for gaseous reactants and products?
No, the subscripts in a balanced chemical equation represent the number of atoms of each element in the reaction. The coefficients in front of the chemical formulas indicate the mole ratios for reactants and products, but volume ratios of gaseous reactants and products are determined by the ideal gas law and the coefficients in the balanced equation.
What information about a chemical reaction is derived from the coefficients in a balanced equation?
The coefficients in a balanced chemical equation provide the mole ratios of reactants and products involved in the reaction. This information is used to determine the amount of each substance consumed and produced in the reaction and to calculate the theoretical yield of a product.
What part of balanced chemical equation give information about the relative numbers of moles of reactants and products involve in a chemical reaction?
The coefficients in a balanced chemical equation give information about the relative numbers of moles of reactants and products involved in a chemical reaction. The coefficients represent the ratio of moles of each substance involved in the reaction.
Why are individual coefficients meaningless in a balanced equation?
In a balanced chemical equation, the coefficients represent the relative ratio of moles of reactants and products, not the actual number of molecules. Changing the coefficients would alter the stoichiometry of the reaction, affecting the amounts of substances consumed and produced. Thus, individual coefficients by themselves do not hold specific physical significance.
What can be added to a chemical equation to make it balanced?
Coefficients can be added in front of the chemical formulas to balance a chemical equation. These coefficients represent the number of molecules or atoms of each substance participating in the reaction. Balancing ensures that the same number of each type of atom is present on both sides of the equation.
