In a half-reaction the charge on the reactant side must the charge on the product side?
In a half-reaction, the total charge on the reactant side must equal the total charge on the product side. This is because of the principle of charge conservation, which states that charge cannot be created or destroyed in a chemical reaction. Therefore, when balancing half-reactions, any changes in oxidation states or the addition of electrons must ensure that the overall charge remains the same on both sides of the equation.
What else can I help you with?
What is the limiting reactant reagent and what is excess reagent in recrystallization?
The Limiting Reactant is the smaller number once you compare the two reactants with one product. The product that you are comparing them both with must be the same. The Excess Reactant is the larger number, or the amount left over in the chemical reaction.
What key feature must a chemical equation have for it to be classified as a combustion reaction?
The product must be oxidized, i.e, Oxygen must be on the reactant side. Also, the reactant will form its oxide and also liberate heat energy. In case of hydrocarbons, Carbon Dioxide, water and heat energy will be liberated and it is a must when writing the chemical equation.
How do you measuring rate of reaction?
You can measure it by how QUICKLY THE REACTANT IS " APPEARING OR DISAPPEARING"BY:jehad mohammad
Why the reaction mixture does not have 50 percent reactant and 50 percent product at equilibrium position?
The ratio of product to reactant is dependant on many different things, from the reactants and products themselves to the pressure, temperature and other parameters of the reaction conditions such as the presence of a catalyst. Some reactions are product favoured by nature and at room temperature and 100kPa will always lie at the product side of the equilibrium at STP. Others, like the Haber Process, are reactant favoured and, without manipulation, will produce very little product. To maximise the product it must be made thermodynamically and entropically favourable for it to do so.
Does an equation indicates the number of atoms of each product and each reactant involved in a reaction?
Not quite. A properly balanced an equation indicates the number of atoms of any elemental product and any elementalreactant involved in a reaction, along with the number of molecules of any molecular compound product and any molecular compound reactant involved in the reaction. The original sentence is deficient because in any chemical reaction, there must be at least one non-elemental product or reactant.
How is a limiting reactant problem different from other stoichiometry problems?
In a limiting reactant problem, you must identify which reactant will be completely consumed first to determine the maximum amount of product that can be formed. Other stoichiometry problems may involve finding the amount of product produced by known quantities of reactants without considering limiting factors.
If one knows the mass and molar mass of reactant A and the molar mass of product D in a chemical reaction one can determine the mass of product D produced by using the?
Balanced chemical equation along with the stoichiometric ratios derived from that chemical reaction. A + B --> 2C mass of A * 1/molar mass of A = moles of A Moles of A * 2 moles of C/mole of A = moles of C Moles of C * molar mass of C = mass of C Also, you must think about limiting reagents, because if there is not enought reactant B to react with the amount of reactant A then the amount of reactant B will limit the production of product C!
According to the law of conservation of mass if two atoms of hydrogen are used as a reactant how many atoms of hydrogen must be part of the product?
If two atoms of hydrogen are used as a reactant, the law of conservation of mass dictates that the total number of hydrogen atoms in the products must also be two. This means that the number of hydrogen atoms remains the same before and after the reaction, so two atoms of hydrogen must be part of the product.
What is the limiting reactant reagent and what is excess reagent in recrystallization?
The Limiting Reactant is the smaller number once you compare the two reactants with one product. The product that you are comparing them both with must be the same. The Excess Reactant is the larger number, or the amount left over in the chemical reaction.

What reactant must be present to support combustion?
Oxygen.
Does an equation indicates the number of atoms of each product and each reactant involved in a reaction?

The original sentence is deficient because in any chemical reaction, there must be at least one non-elemental product or reactant.
Why does a reaction stop when the limiting reactant is consumed even though there is plenty of the other reactants present?
For a reaction to occur all the reactants are required. If there is no supply of one of the reactants the reaction must stop because there isn't any more of it to keep reacting. When one of the reactants is in low supply or runs out it is called the limiting reactant.
What is a limiting agent?
In many chemical reactions, there are two reactants. In nearly every case, one of those two reactants "runs out" first, and at that point, the chemical reaction stops, because in order for it to happen, both reactants must be present to react with each other. As soon as the one reactant runs out, the reaction is over, and you have product(s) and one left over reactant. The reactant that runs out first is the limiting reactant. The leftovers are the excess reactant.
What is the limiting reactant in 2H2(g) O2(g)2H2O(l)?
In the reaction 2H₂(g) + O₂(g) → 2H₂O(l), the limiting reactant is the substance that is completely consumed first, thereby determining the maximum amount of product formed. To identify it, one must compare the mole ratios of the reactants to the coefficients in the balanced equation. If you have more than enough of one reactant (e.g., H₂) relative to the stoichiometric requirement based on the amount of the other reactant (O₂), then O₂ is the limiting reactant, and vice versa. Without specific quantities, the limiting reactant cannot be determined definitively.
