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.
How are linear equations used in business?
liner equations can b used in business for getting the rough estimate of the profit or loss using a variable in the place of a quantity which is unknown.
When does the nonlinear equation becomes linear equation?
A linear equation is defined as an equation that contains only the first power of the unknown quantity. For example, 5x - 3 = 7 where "x" is the unknown quantity is a linear equation. If an equation contains an unknown quantity having a higher power than 1, then the equation ceases to be a linear equation. For example, 3x2 + 5x + 7 = 0 is a non linear equation known as a quadratic equation, because the unknown quantity "x" has a power of 2. Similarly, equations containing unknowns with higher powers such as x3, x7, x12 are all non linear equations.
What is the highest exponet of the leading variable in a linear equation?
A linear equation contains only the first power of the unknown quantity. Thus, 5x - 3 = 7 and x/6 = 4 are both linear equations.
What are vector quanity?
Any quantity for which a direction is relevant.Any quantity for which a direction is relevant.Any quantity for which a direction is relevant.Any quantity for which a direction is relevant.
Why is it essential to use balanced chemical equations when determining the quantity of a product fo?
Using a balanced chemical equation ensures that the mole ratio between reactants and products is accurate. This allows for precise calculations of the quantity of a product formed in a chemical reaction. Without a balanced equation, incorrect conclusions may be drawn regarding the amount of product produced.
What does a balanced chemical equation prove?
One or more products containing the same quantity of atoms as the reactants had
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.
Why should you never change a subscript when attempting to balance chemical equations?
Changing subscripts changes the identity of the compound, not just its quantity. Instead, you should balance chemical equations by adjusting coefficients in front of the chemical formulas to ensure the same number of atoms for each element on both sides of the equation.
What is the problem solving method in chemistry that uses mathematical relationships to convert one quantity to another?
The problem solving method you are referring to is stoichiometry. This method involves using balanced chemical equations and conversion factors to determine the relationship between reactants and products in a chemical reaction. This allows you to calculate the amounts of substances involved in a reaction based on the quantities of other substances.
What information in a balanced chemical equation shows how many miles of a reactant are involved in the reaction?
A balanced chemical equation does not provide information on the physical amount or quantity of reactants involved in a reaction, such as miles. The coefficients in a balanced chemical equation represent the mole ratio of reactants and products, not physical quantities like miles. To determine how many moles or amount of reactant is involved in a reaction, one would need to use stoichiometry calculations based on the coefficients in the balanced equation and known quantities.
What is a changeable quantity called?
A changeable quantity is called a variable. Variables can take different values and are typically represented by letters in mathematical equations.
Why are symbols used in a chemical equation?
Symbols are used in a chemical equation to represent the elements or compounds involved in a chemical reaction. These symbols make it easier to understand the reactants and products, as well as the stoichiometry or quantity relationships between them. Symbols also help to balance chemical equations by ensuring that the number of each type of atom is conserved in the reaction.
What does unequal mean?
poorly balanced or matched in quantity or value or measure
How are ratios related to chemical equations?
Ratios play a crucial role in balancing chemical equations. The coefficients in a balanced chemical equation represent the ratio in which reactants combine and products are formed. This ratio ensures that the law of conservation of mass is upheld in chemical reactions.
What does a balanced chemical equation convey to a chemist?
A balanced chemical equation shows the identities and relative quantities of reactants and products involved in a chemical reaction. It indicates the stoichiometry of the reaction, meaning the molar ratio of the substances involved. This information is crucial for predicting the outcome of the reaction and for calculating the amounts of substances needed or produced.
What is equilibrium price and quantity?
It is where quantity demanded equals quantity supplied Say you have an equation for quantity demanded (Qd) and quantity supplied (Qs) Qd= 11 - 2p and Qs= -5 + 2p you set the two equations equal to each other to find the price (p) 11 - 2p = -5 + 2p 16 = 4p [p = 4] then substitute the price (p) in any of the equations to find the quantity Qd = 11 - 2(4) [Qd = 3]
