“Disciplinary literacy is about preparing young people for more and more specialized ways of thinking about knowledge. Generalist literacy, on the other hand, seeks to support reasoning and critical thinking relevant to everyday decision making—often about topics about which we have no specialized understanding or knowledge.”

What makes a chemical reaction balanced?
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
Which of the following are used to balance a chemical reaction equation?
CoefficientsCoefficients are used to balance chemical equations. A coefficient is a number placed in front of a chemical symbol or formula. It shows how many atoms or molecules of the substance are involved in the reaction.
Which of the following is an example of a balanced chemical equation?
In a balanced chemical equation, the total mass of each of the elements in the reactants is same as the total mass of the respective elements in the product. For example: `2NaOH + H_2SO_4 to Na_2SO_4 + 2H_2O` is a balanced equation.
How do you make a balanced chemical equation?
To write a balanced equation, the reactants go on the left side of the arrow, while the products go on the right side of the arrow. Coefficients (number in front of a chemical formula) indicate moles of a compound. Subscripts (numbers below an atom) indicate the number of atoms in a single molecule.
Which of the following is true for a balanced equation?
The correct statement for a balanced chemical equation is A. The number of atoms of each kind on each side should be equal. This is because in a balanced chemical equation the atoms of each of the elements on both sides, the reactant side, and the product should be equally balanced with the help of coefficients.

How to balance a chemical equation?
Perform the following check: Add up the numbers of each type of atom. The total number of atoms in a balanced equation will be the same on both sides of the equation.
What is a balanced equation?
A balanced equation contains the same number of each type of atoms on both the left and right sides of the reaction arrow. To write a balanced equation, the reactants go on the left side of the arrow, while the products go on the right side of the arrow. Coefficients (number in front of a chemical formula) indicate moles of a compound.
How to check if an equation is balanced?
Check Equations to Make Sure They Are Balanced 1 When you balance a chemical equation, it's always a good idea to check the final equation to make sure it works out. Perform the following check: 2 Add up the numbers of each type of atom. The total number of atoms in a balanced equation will be the same on both sides of the equation. The Law of Conservation of Mass states the mass is the same before and after a chemical reaction. 3 Make sure you accounted for all types of atoms. Elements present on one side of the equation need to be present on the other side of the equation. 4 Make sure you can't factor out the coefficients. For example, if you could divide all of the coefficients on both sides of the equation by 2, then you may have a balanced equation, but not the simplest balanced equation.
What do the coefficients and subscripts mean in chemistry?
Coefficients (number in front of a chemical formula) indicate moles of a compound. Subscripts (numbers below an atom) indicate the number of atoms in a single molecule. To calculate the number of atoms, multiply the coefficient and the subscript.
Do you factor out coefficients on the other side of an equation?
Elements present on one side of the equation need to be present on the other side of the equation. Make sure you can't factor out the coefficients. For example, if you could divide all of the coefficients on both sides of the equation by 2, then you may have a balanced equation, but not the simplest balanced equation.
