Chemists keep track of which substances are used and created in a chemical reaction by writing what?
Chemists keep track of substances used and created in a chemical reaction by writing a balanced chemical equation. This equation accounts for the reactants (substances used) and products (substances created) in terms of their chemical formulas and stoichiometry. Balancing the equation ensures that the law of conservation of mass is obeyed.
How can the change in overall mass be explained?
The change in overall mass can be explained by the principle of conservation of mass, which states that mass cannot be created or destroyed in a closed system. When substances undergo chemical reactions or physical changes, the total mass remains constant; however, mass may appear to change due to the release or absorption of energy, phase transitions, or the formation of products that have different properties. Additionally, external factors such as the addition or removal of materials can also influence the overall mass of a system.
What is the overall definition that includes mixtures compounds and elements?
The overall definition that includes mixtures, compounds, and elements is matter. Matter refers to anything that has mass and takes up space. Mixtures are combinations of different substances that can be physically separated, compounds are substances composed of two or more elements chemically bonded, and elements are pure substances composed of only one type of atom.
What is the mass of a dog if it has a mass of 10 kilograms plus half of its mass?
The mass of the dog can be calculated by setting up an equation. If we let x be the mass of the dog, then the equation would be x = 10 + 0.5x. Solving this equation, we find that the mass of the dog is 20 kilograms.
What is the equation of conversion of mass?
This is the one we use for Organic substances, not sure if it works otherwise, :)CxHy + (x + y/4) O2 ===> XCO2 + y/2 H2OEx.C6H14 + (6 + 14/4) O2 ====> 6CO2 + 14/2 H2O= C6H14 + 9.5O2 ====> 6CO2 + 7H2O
Which statement correctly compares the reactants and products of the equation?
The total mass of reactants is equal to the total mass of products.
What happens to mass when substances go through a chemical change?
The total mass of products is unchanged from the total mass of the reactants, but the masses of particular substances among the reactants or products change.
A balanced chemical equation allows you to determine the?
A balanced chemical equation allows you to determine the ratio of reactants consumed and products produced in a chemical reaction. It also allows you to calculate the amounts of substances involved in the reaction based on the stoichiometry of the equation.

Why is force needed?
Force happens when an object of mass is accelerated, and the equation to calculate force is : force=mass/acceleration
Explain how a balanced chemical equation show that mass is conserved?
A balanced chemical equation demonstrates the law of conservation of mass because the total mass of the reactants equals the total mass of the products. This means that no atoms are created or destroyed during a chemical reaction; they are simply rearranged to form new substances.
Can mass of a body become zero?
The only condition where mass can be extinguished is if it is converted into energy. When this happens it obeys the well known equation E=mc2
What happens to the the mass of something when it is burned?
When something is burned, its mass remains the same. The substances that are being burned undergo chemical reactions, where they are broken down into different molecules. However, the total mass of the substances before and after the burning process remains constant due to the law of conservation of mass.
When is the principle of a conservation of a mass number satisfied in a chemical equation?
The principle of conservation of mass is satisfied in a chemical equation when the total mass of the reactants is equal to the total mass of the products. This means that no atoms are lost or gained during the reaction, they are just rearranged to form new substances.
When you get your haircut what happens to your mass?
Unless you're a freak of nature or something, getting a haircut is going to have a negligible impact on your overall mass.
The equation of atomic mass?
