The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction, only rearranged. In order to adhere to this law, chemical equations must be balanced to ensure that the same number of each type of atom is present on both the reactant and product sides of the equation. This balancing of chemical equations ensures that mass is conserved throughout the reaction.

Why do scientists have to make sure chemical equations are balanced?
Balancing a chemical equation establishes what proportions of the reactants are required for complete reaction as well as the proportions of the products of the reaction. Some factors in balancing the equation will also dictate what the products ARE. For example - when balancing the equation for a combustion reaction, the presence of nitrogen in the fuel molecule will yield certain products while it's absence will exclude certain products. Likewise, when performing electrochemical reaction balances, balancing the electrochemistry will dictate the products of the reaction.
Why does the law of conservation of mass dictate the chemical equation be balanced?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. Therefore, in a balanced chemical equation, the number of atoms of each element must be the same on both sides to ensure that mass is conserved. If the equation is unbalanced, it would imply that mass is not conserved, which goes against this fundamental law of chemistry.
What is the significance of electron subshells in determining the chemical properties of an element?
Electron subshells play a crucial role in determining the chemical properties of an element because they dictate how electrons are arranged around the nucleus. The number and arrangement of electrons in the subshells influence an element's reactivity, bonding behavior, and overall chemical characteristics.
What properties of substance determine how that substance will react when combined with other substances?
Chemical
The chemical behavior of atoms is determined by the?
number of protons in the nucleus and the arrangement of electrons in the atom's energy levels. The number of protons determines the element's identity, while the electrons dictate how atoms interact with other atoms to form molecules through chemical bonding.

What is the future tense of dictate?
Will dictate.
Can energy be created and sometimes destroyed?
No. The laws of conservation of energy dictate that energy can neither be created nor destroyed. Mass and energy are equivalent, so energy can only change forms.
What s not changed when work is done by a machine?
When work is done by a machine, the fundamental principles of physics governing the conservation of energy and conservation of momentum remain unchanged. These laws dictate that energy cannot be created or destroyed, only transferred or converted, and that momentum will be conserved in any isolated system.
What part of speech in dictate?
The word dictate is a verb. Mrs. Jones will dictate a letter now.
What is the noun for dictate?
The word dictate is both a noun and a verb. Example uses: Noun: The dictate of my conscience is to tell the truth. Verb: I'm your boss and I dictate what your job is.
What part is speech is dictate?
The word dictate is a verb.
What part of speech is dictate?
The word dictate is a verb.
What are conservation laws obey in each of the nuclear reaction?
Conservation laws in nuclear reactions include conservation of mass-energy, conservation of electric charge, conservation of momentum, and conservation of lepton number. These laws dictate that the total mass-energy of particles before and after a nuclear reaction must remain constant, as well as the total charge and momentum. Lepton number conservation ensures the number of leptons (like electrons and neutrinos) remains the same throughout the reaction.
How do you make a sentnce with verdict and dictate?
The judge reached a verdict. He proceeded to dictate the memo.
How much C2H4N2 could be expected from the reaction of 13.6 grams CO2 2.21 grams NH3 and 1.64 grams of CH4?
To determine the expected yield of C2H4N2 from the reaction of CO2, NH3, and CH4, we first need to identify the balanced chemical equation for the reaction. Assuming the reaction is balanced, we would calculate the moles of each reactant (CO2, NH3, and CH4) and identify the limiting reagent. The limiting reagent will dictate the maximum amount of C2H4N2 that can be produced. Since specific stoichiometric coefficients are not provided, you would need to perform these calculations based on the balanced equation to find the exact mass of C2H4N2 produced.
