What is any mathematical statement that declares the values of two mathematical expressions to be equal?
That is called an equation. An equation has an equal sign (=), and expressions on both sides of the equal sign.
When two sides of an equation are equal what phrase is used?
Equality. If they are ALWAYS equal then the equation is an identity.
What reduces a equation that has two variables to an equation that has one variable?
combining like terms or subtracting from both sides of the equation.
What is an object having two sides called?
A PLANE has two sides
What is an object with two sides called?
There is no such thing as an object with two sides.
The two sides of a chemical equation?
Reactants -> Products
How many copies of O2 are required to balance this chemical equation?
To balance the chemical equation, the chemical formula O₂ indicates two oxygen atoms bonded together. The number of O₂ molecules needed to balance the equation would depend on the number of oxygen atoms present on both sides of the equation.
How does a chemical equation show that a chemical reaction has occurred?
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
The chemical reaction between two or more substances is described using what equation?
A chemical reaction between two or more substances is described using a chemical equation. It shows the starting materials, called reactants, and the resulting products, along with the chemical formulas and proportions of each component involved in the reaction.
What do you mean by balanced chemical equation?
A balanced chemical equation is one where the number of the same atoms on both sides are equal. A balanced chemial equation is important because during a chemical reaction, there is rearrangement of atoms only and no new atoms are added. To understand the concept of a balanced chemical equation, first consider an unbalanced chemical equation between magnesium and oxygen to form magnesium oxide. Unbalanced chemical equation: Mg(s) + O2(g) --> MgO(s) Initially, this equation is unbalanced because if we count the number of the oxygen atoms on both sides, the number are unequal. There are two oxygen atoms on the left side but only one on the right side. A balanced chemical equation is one where the number of all of the same atoms on both side are equal. We can balance chemical equations by adding numbers to the coefficient of the chemicals that are involved in the reaction. Balanced chemical equation: 2Mg(s) + O2(g) --> 2MgO(s) This equation is now balanced because if we count the number of the same atoms on both side, they are equal. There are two magnesium atoms and two oxygen atoms on both sides of the equation.

New compounds made during chemical reactions are?
1. A chemical equation is a concise shorthand expression which represents the relative amount of reactants and productsinvolved in a chemical reaction. The skeleton equation indicates that two hydrogen atoms react with two oxygen atoms on the reactant side of the equation.
How can I tell if a chemical reaction is balanced or not balanced?
You can tell if a chemical reaction is balanced by ensuring that the number of atoms of each element is the same on both sides of the reaction equation. If the number of atoms of each element is not the same, then the reaction is not balanced. Balancing a chemical reaction involves adjusting coefficients in front of the chemical formulas to equalize the number of atoms on both sides.
What are the two methods for balancing the chemical equation?
The two methods for balancing a chemical equation are the inspection method and the algebraic method. In the inspection method, you visually adjust the coefficients of the chemical compounds to achieve balance. In the algebraic method, you set up mathematical equations based on the number of atoms of each element on both sides of the equation and solve for the coefficients.
Why is the chemical equation H2 plus O2 equals H2O is not balanced?
The chemical equation H2 + O2 -> H2O is not balanced because the number of oxygen atoms is not equal on both sides of the equation. There are two oxygen atoms on the left side (O2) and only one on the right side (H2O). Balancing the equation would require adding a coefficient of 2 in front of H2O to have an equal number of oxygen atoms on both sides.
Which is a balanced chemical equation according to the law of conservation of mass?
A balanced chemical equation is one in which the number of atoms of each element is the same on both the reactant and product sides. This follows the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only rearranged. For example, the equation 2H2 + O2 -> 2H2O is balanced because there are 2 hydrogen atoms and 2 oxygen atoms on both sides of the equation.
What equates in a chemical equation?
Two (or more) substances react and new substances are formed.
