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.
Why is Cl2 plus 2Nal-2NaCl plus I2 a balanced equation?
The equation is balanced because the number of each type of atom is the same on both sides of the equation. There are two Cl atoms on the left side and two Cl atoms on the right side, two Na atoms on the left side and two Na atoms on the right side, and two I atoms on the left side and two I atoms on the right side.
How do you balance C6H1206 02-C02 H20?
To balance the chemical equation C6H12O6 + O2 → CO2 + H2O: Start by balancing the carbon atoms by placing a coefficient of 6 in front of CO2. Balance the hydrogen atoms next by placing a coefficient of 6 in front of the H2O. Lastly, balance the oxygen atoms by placing a coefficient of 6 in front of O2 on the left side of the equation. The balanced equation is: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O
If five atoms of hydrogen are reactants in a chemical reaction then how many atoms of hydrogen will be found in the products of that reaction?
If five atoms of hydrogen are reactants in a chemical reaction, typically all five atoms will be found in the products unless some sort of splitting or rearrangement of atoms occurs during the reaction. It follows the principle of conservation of mass, meaning atoms cannot be created or destroyed in a chemical reaction.
How do you balance CuCl Cl2 - CuCl2?
To balance the equation Cu + Cl2 → CuCl2, you need to make sure there are the same number of atoms on each side: 2 Cu atoms on the left, 2 Cl atoms in CuCl2, and 2 Cl atoms in Cl2. So, the balanced equation is Cu + Cl2 → CuCl2.
How do you check that an equation is balanced?
Make sure that the number of atoms on the left side of the equation is the same as the number of atoms on the right side.For example: -H + O2 --> H2O This is not a balanced equation because there is more oxygen and less hydrogen on the left side of the equation then is needed on the right side.4H + O2 --> 2H2O This equation is balanced because there is 4 hydrogen atoms and 2 oxygen atoms on both sides of the equation.
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.
What does balance the equation mean?
In terms of Chemistry it means to make sure that there are equal numbers of atoms on both sides of the equation. For example, H2O2 +O2 = OH + O2 is not balanced as there are only four atoms of oxygen and two atoms of hydrogen on the left, and there are 3 atoms of oxygen and an atom of hydrogen on the right. To balance it, you make it so that it looks like this: H2O2 + O2 = 2OH + O2. Now, you have 2 atoms of hydrogen on the left with four atoms of oxygen, and 2 atoms of hydrogen on the right with four atoms of oxygen. Here is another balanced equation: 6 CO2 + 12 H2O + energy → C6H12O6 + 6 O2 + 6 H2O Carbon dioxide and water plus energy yields sugar, oxygen, and water. This essential chemical reaction is known as photosynthesis.
How many oxygen atoms are left after photosynthesis?

Why is Cl2 plus 2Nal-2NaCl plus I2 a balanced equation?
The equation is balanced because the number of each type of atom is the same on both sides of the equation. There are two Cl atoms on the left side and two Cl atoms on the right side, two Na atoms on the left side and two Na atoms on the right side, and two I atoms on the left side and two I atoms on the right side.
Balance Li2CO3 to Li2O plus CO2?
No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.
In a chemical balancing equation what is to the left and right?
In a chemical equation, the reactants are on the left side, while the products are on the right side. The number and type of atoms in the reactants must be equal to the number and type of atoms in the products for the equation to be balanced.
How do you balance P4O10 plus H2O equals H2PO4?
P4 3o2 ---> 2po5
What is a balanced equation in science?
a balanced equation is when all matter is accounted for on both sides. This is important because matter cannot be created or destroyed. For example, the creation of glucose through photosynthesis looks like this: CO2 + H2O = C6H12O6 + O2 + H2O This is an unbalanced equation because there is not enough oxygen, hydrogen, and carbon on the left side to create the right side. The balanced equation would be: 6 CO2 + 12 H2O = C6H12O6 + 6 O2 + 6 H2O The number of oxygen, hydrogen, and carbon atoms on each side, when subtracted, create 0 which means all matter is accounted for and therefore the equation is balanced
How many atoms does oxygen have on the left hand side of an equation?
In a chemical equation, the number of atoms on each side must be balanced according to the Law of Conservation of Mass. For oxygen, the number of atoms can vary depending on the specific compound involved in the reaction. To determine the number of oxygen atoms on the left-hand side of an equation, you would need to look at the stoichiometry of the reaction being described.
Balance the formula example?
Hcl + Mg --> MgCl2 + H2 This equation has an unbalanced amount of atoms on each side. To work out the balanced formula you need to find the number of atoms of each side. There are: 1 Hcl + 1 Mg ---> 1Mg 2Cl + 2H Bear in mind you cannot change a "clump" of elements, as this changes the reaction (MgCl2). So, to get the equal number of atoms, you simply put in a number at the start of each "clump" to multiply it and even out, sort of like expanding a set of brackets in maths. In this equation we want to put a 2 in front of Hcl to multiply the Hydrogen atom and get 2 hydrogen atoms (therefore balancing with the left side). Doing so will then multiply the chlorine atoms by 2, giving 2 chlorine atoms. So now there are: 2Hcl + Mg --> MgCl2 + H2 (2 hydrogen atoms, 2 chlorine atoms, 1 magnesium atom on the left. one magnesium atom two chlorine atoms and 2 hydrogen atoms on the right) and that's it. the equation is balanced, easy as that... If you get it try this one, Na + H2O --> NaOH + H2. Answer will be down here.... ---- 2Na + 2H2O --> 2NaOH + H2
Is 2Na plus S and 2NaS considered a balanced equation?
Consider firstly if there are equal numbers of atoms of each element on either side of the reaction. No, there aren't: there are too many sodium, chloride ions and hydrogen atoms on the reactant side, so the equation is not balanced.
