This is called balancing an equation. First you determine what the products are from the reactants. Assuming ionic bonding, i.e. plus balances out minus charge.
So you start out with the reaction:
H2SO4 + NaOH = ?
Ions present H+, SO42-, Na+, OH-. Mix and match them gives you Na2SO4 and HOH (H2O)
So you now have H2SO4 + NaOH => Na2SO4 + H2O
Then comes the balancing atoms on either side of the equation. This can only be done by putting numbers in front of molecules (cannot change overall charge of molecule by changing amount of atoms in a molecule)
Look for what there aren't enough. In this case it is Na firstly. Make it 2NaOH, then you have an extra OH, so make it 2H2O, and hey presto, balanced eq is the following:
H2SO4 + 2NaOH => Na2SO4 + 2H2O
What else can I help you with?
How can I tell if a chemical reaction is balanced or not balanced?
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
When a chemical equation contains the same number of atoms on both sides is the equation balanced?
Yes, a chemical equation is considered balanced when the same number of each type of atom is present on both the reactant and product sides of the equation. This ensures that mass is conserved during the reaction.
How do you balance a equation with Na and Phosphate?
To balance an equation involving sodium (Na) and phosphate (PO4), ensure the number of sodium atoms is equal on both sides by adding coefficients. For example, in the reaction Na3PO4 + CaCl2 -> Ca3(PO4)2 + NaCl, balance by adding a coefficient of 3 in front of NaCl to ensure equal numbers of sodium atoms on both sides.
How can use the law of conservation of mass to help you balance a chemical equation?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction, so the number of atoms of each element must be the same on both sides of the equation. By balancing a chemical equation, you ensure that the total number of atoms of each element in the reactants is equal to the total number of atoms in the products, thus preserving mass.
Is cucl2 h2s cus 2hci a balanced equation?
CuCl2 + H2S --> CuS + 2HCl Yes, this is the balanced equation here.
How many atoms of hydrogen appear on each side of the equation?
To determine the number of hydrogen atoms on each side of the equation, you would need to balance the equation first. Once the equation is balanced, count the number of hydrogen atoms on both the reactant and product sides to compare. The number of hydrogen atoms should be the same on both sides of the balanced equation.
How can one determine if a chemical equation is balanced?
A chemical equation is balanced when the number of atoms of each element is the same on both sides of the equation. To determine if a chemical equation is balanced, count the number of atoms of each element on both sides and adjust the coefficients of the compounds to make them equal.
What term means equal numbers if atoms exist on each side of a chemical equation?
A Balanced equation is one where equal number of atoms exist on either side.
How do you tell if a equation is balanced?
An equation is balanced when the number of atoms of each element is equal on both sides of the equation. This means that the total mass and charge is conserved. You can check if an equation is balanced by counting the number of atoms of each element on both sides of the equation and adjusting coefficients as needed.
How can you determine if a chemical equation is balanced?
A chemical equation is balanced when the number of atoms of each element is the same on both sides of the equation. To determine if a chemical equation is balanced, count the number of each type of atom on both the reactant and product sides and adjust the coefficients in front of the chemical formulas to make the number of atoms equal on both sides.
What are both sides of an equation equal to?
In Chemistry, this is the known as the Law of Conservation of Matter. While the moles of individual substances may change, the number of atoms of reactants is the same as the number of atoms of products.
A number placed in front of the chemical formula in a chemical equation is called a?
coefficient. It is used to balance the equation by ensuring that the number of atoms of each element on both sides of the equation is equal.
What is a balance between products sides and reactants sides of the equation?
A balanced chemical equation is one in which the number of atoms on the product side is equal to the number of atoms on the reactant side. This ensures the law of conservation of mass is upheld, meaning that no atoms are created or destroyed during a chemical reaction.
What do you count to decide whether or not an equation is balanced?
If you count all of the atoms of each element on the left and all the atoms of each element on the right and the numbers on the left and right are equal for EVERY element, then the equation is balanced.
What is a chemical equation in which both reactant and product have an equal number of atoms of a given element?
A chemical equation where both the reactant and product have an equal number of atoms of a given element is called a balanced chemical equation. This means that the law of conservation of mass is satisfied, and the total number of each type of atom is the same on both sides of the equation.
What is the balanced chemical equation for CaCO3 to CaO plus CO2?
The equation is already balanced:CaCO3(s) --> CaO(s) + CO2(g)ExplanationA balanced chemical equation is one where the number of atoms on both sides are equal. Chemical equations must be balanced because there is only a rearrangement of atoms in a reaction so the number of atoms you start off with must be the same as the number of atoms you end up with.If we take a look at the equation, we can see that there is 1 calcium atom, 1 carbon atom and 3 oxygen atoms present on both sides. As the number of these atoms on both sides are equal, the equation is balanced.
What equates in a chemical equation?
Two (or more) substances react and new substances are formed.
