What is a balanced chemical reaction? What happens when you mix vinegar and bicarbonate of soda? What must happen for a chemical reaction to occur? What is the starting substance in a chemical reaction? What are examples of neutralization reactions?
What is the balanced chemical equation?Chemical Equation:The chemical equation can be considered as the symbolic representation of the chemical reaction of the different molecules and compounds. It gives information about the quantitative data of the reaction.Answ...
1) All chemical equations are must be balanced, because atoms are neither created nor destroyed in a chemical reaction. 2) Law of mass of conservation should be followed. 3) A chemical equation in which the number of atoms of different elements on th

About the silver nitrate and copper reaction. we must consider it in two different directions. One would be that copper is a transition metal, so therefore it's multivalent. It can have a 1+ or 2+ charge, right? if you consider it with the 1+ charge, the balanced chemical equation ...
:** An example of an endothermic reaction that occurs every day in Earth's atmosphere is the combination of molecular oxygen with molecular nitrogen to form nitric oxide. Chemists know exactly how much heat energy it takes for this reaction to occur. The balanced equation for this reaction is...
The second condition is equivalent to the existence of a strictly positive reaction invariant. Furthermore, it is sufficient for the existence of a realization in terms of sum formulas, obeying conservation of "atoms". In particular, these realizations can be chosen such that any two species ...
i. The reaction in which one type of atom/group of atoms in a reactant is substituted by another atom/group of atom is called substitution reaction. ii. Chlorination of methane is a substitution reaction which gives four different hydrocarbons as produ
The initial step is to write the balanced chemical equation representing the reaction. Balanced chemical equation: {eq}\rm C_3H_8 + 5O_2... Learn more about this topic: Mass to Mass Stoichiometry | Overview, Conversion & Problems
A balanced chemical reaction equation provides a set of stoichiometric coefficients that are important in various calculations. For example, the reactant stoichiometric ratio can be compared to a starting ratio of reactant molar quantit...
