∙ 12y agoIf 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.
Mass is conserved in a chemical reaction, so the mass before must equal the mass after. If you have five atoms before, you must have five atoms after.
i was looking at my brother's homework and it asked that question and he left it blank. can u list some organic molecules? there is a multitude of molecules that contain hydrogen and carbon and any molecule containing this combination is said to be organic. molecules not containing carbon and hydrogen are called inorganic.
the sodium and hydroxide atoms separate into ions and the positive sodium ions are attracted to the oxygen atoms and the hydroxides are attracted to positive charged part of water, the hydrogen making another molecule.
The requirement for a balanced equation is that the numbers of each kind of atoms in the reactants must match the number of each kind of atoms in the products. The number of atoms in each molecule in the equation is the product of the coefficient and the subscript affixed after each element symbol in the formula to which the coefficient applies. For example, 2 Na + Cl2 = 2 NaCl. The coefficients on the left side total 3 but those on the right side total only 2. However, the number of atoms of each of sodium and chlorine total 2 on each side.
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.
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.
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.

That the number of atoms on the left side of the equation must be the same number of atoms that are on the right side of the equation.
2 halves of a hydrogen atom.
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.
This is the law of mass conservation.
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
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.
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
