Reactants are the starting materials in a chemical reaction that undergo a change to form new substances called products. Reactants are consumed during the reaction, while products are the end result of the reaction. The reactants are typically written on the left side of a chemical equation, while the products are written on the right side. **

Limiting reactants, also known as limiting reagents, are the reactants in a chemical reaction that are completely consumed, thus limiting the amount of product that can be formed. In other words, they determine the maximum amount of product that can be produced in a reaction. The concept of limiting reactants is important in stoichiometry, as it helps to determine the theoretical yield of a reaction and identify the excess reactant that will be left over after the reaction is complete. **

To calculate reactants in chemistry, you first need to write a balanced chemical equation for the reaction. Then, determine the molar ratio between the reactants and the product in the balanced equation. Next, calculate the number of moles of the known reactant using its given mass or volume and its molar mass. Finally, use the molar ratio to calculate the number of moles of the other reactant needed for the reaction. **

No, redox reactions involve both reactants and products. In a redox reaction, one substance undergoes oxidation (loses electrons) while another undergoes reduction (gains electrons). Therefore, both the reactants and products are involved in the redox process. The reactants are the starting materials that undergo the redox reaction, while the products are the resulting substances after the redox reaction has occurred. **

To calculate the reactants in a chemical reaction, you first need to write out the balanced chemical equation for the reaction. Then, you can use stoichiometry to calculate the amount of reactants needed based on the desired amount of product. This involves using the coefficients in the balanced equation to set up conversion factors and then using these conversion factors to calculate the amount of reactants required. Finally, you can use the molar mass of the reactants to convert between mass and moles if necessary. **

To calculate the required amount of reactants, you first need to determine the balanced chemical equation for the reaction. Then, you can use stoichiometry to convert the given amount of one reactant to the amount of the other reactant needed for the reaction. This involves using the molar ratios from the balanced equation to convert between moles of the given reactant and moles of the required reactant. Finally, you can use the molar mass of the required reactant to convert from moles to the required amount in grams or other units as needed. **

In a chemical reaction, the reactants are the substances that undergo a chemical change to form new substances called products. Reactants are the starting materials that are transformed into products during the reaction. The products are the end result of the chemical reaction, formed from the rearrangement of atoms in the reactants. The reactants are consumed during the reaction, while the products are the new substances that are produced. **

The reactants do not disappear in chemical reactions because of the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Instead, the reactant molecules are rearranged and their bonds are broken and formed to produce new products. This means that the total mass of the reactants is conserved and is equal to the total mass of the products. Therefore, the reactants do not disappear, but rather undergo a transformation into new substances. **
