What law of physical science must be followed when balancing chemical?
The law of conservation of mass must be followed when balancing chemical equations. This law states that the total mass of the reactants must equal the total mass of the products in a chemical reaction.
Which one is a step used for balancing chemical equations?
Count the atoms in each substance in the reactants and products. (Apex)
Why are state symbols used in a chemical equations?
State symbols in chemical equations are used to indicate the physical state of the substances involved (solid, liquid, gas, or aqueous solution). This information is important because the physical state can affect the reaction conditions and the behavior of the substances in the reaction. Including state symbols provides a more complete and accurate representation of the chemical reaction.
What are the limitations of the chemical equation?
Chemical equations do not provide information about the speed of a reaction, the conditions under which a reaction occurs, or the purity of the reactants. They also do not account for side reactions or variations in reaction pathways. Additionally, chemical equations do not indicate the physical state of reactants and products or the equilibrium state of a reaction.
Which law of physical science mustbe followed when balancing chemical equations?
Initial answer - (which happens to be wrong - but has been kept because it illustrates a misunderstanding that you want to avoid): has to have the same number of moles on both side because u cannot make or destroy moles mmm ... not exactly As an example, the combustion of hydrogen is 2H2 + O2 ==> 2H2O In this example you could start with 3 moles (2 moles of H2 and 1 mole of O2) and wind up with 2 moles (of H2O). The law that must be obeyed is "Conservation of mass". Using the example above, you start with 4 hydrogen atoms and 2 oxygen atoms in the reactants and end with 4 hydrogen atoms and 2 oxygen atoms in the products. The mass is conserved.

Do chemical equations show summaries of physical change?
Chemical equations show the identities of the substances involved in a chemical reaction and the ratios in which they react or are produced. They do not provide a summary of physical changes such as changes in state or appearance. Physical changes involve alterations in the physical properties of a substance without changing its composition.
Do chemical equations have no real structure?
Chemical equations provide a written representation of a chemical reaction by showing the relationship between reactants and products. While they do not have a physical structure like molecules, they are structured to follow the law of conservation of mass and allow scientists to understand the stoichiometry of a reaction.

Which is chemical equation?
A chemical Equation is a shorthand form of a chemical reaction. chemists use it to help them tell the substances that are present such as reactants, products, or proportions.Some equations also tell the physical state of a substance.

What are state symbols used for in chemical equations?
State symbols in chemical equations indicate the physical state of the reactants and products involved, such as (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous solution. They provide crucial information about the conditions under which a chemical reaction occurs, helping to accurately represent the reaction taking place.
Is a change that produces a new element a physical change?
No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.
Is stapling an envelope a physical change or chemical?
A physical change
Why are the state symbols used in chemical equations?
State symbols are used in chemical equations to indicate the physical state of a substance involved in the reaction, such as solid (s), liquid (l), gas (g), or aqueous solution (aq). This information helps to accurately represent the reaction conditions and ensure that the equation is balanced correctly.
