Is matter being lost when burning a log?
In a chemical reaction the mass of reactants is equal to the mass of products; burning is a chemical reaction.
What is the reaction in which water is lost from the reactants?
dehydration
How does the law of conservation of mass related to balancing of chemical reaction?
The Conservation of Matter states that matter cannot be destroyed or created. Therefore in a reaction the masses of the reactants and products remain constant. In balancing a reaction the law applies in that all atoms must be accounted for and equalized across both sides of the equation.
Who is hypothesis that matter is conserved during a chemical reaction?
This theory was made in 1807 by John Dalton.
What is the mass difference between water and hydrogen plus oxygen?
The mass of water would be equal to the mass of oxygen plus the mass of hydrogen used in the reaction. The law of the conversation of mass states that in a reaction no mass is either gained or lost. In this case the total amount of mass of the reactants (Oxygen and Hydrogen), according to the law of the conversation of mass, must be equal to the product (water), because no mass can be lost or gained during the reaction.
How the diagram you have drawn shows that no mass is lost during the reaction?
Calculating the mass of reactants and products in a chemical reaction is a sufficient demonstration.
Is matter being lost when burning a log?
In a chemical reaction the mass of reactants is equal to the mass of products; burning is a chemical reaction.
How does mass of the reactants compare with the mass of the products?
The Law of Conservation of Mass applies. The total mass of all the reactants MUST equal the total mass of all the products, The individual comoounds may vary. e,g, A + B = C + D 25 g (A) + 30g (B) = 55 g of reactants. So the total mass of the products MUST equal 55 g. However, product (C) may have a mass of 40g , then product (D) MUST equal 15 g Hence 40 g + 15 g = 55 g,
How does a balanced chemical equations how that mass is never lost or gained in a chemical reaction?
if you balanced the equation correctly then the sum of the reactants will equal the sum of the the products because if there is the same amount of atoms on the reactants and the products obviously none is lost.
What is the law of conservation in mass?
The law of conservation of mass states that matter cannot be created or lost in a chemical reaction. The weight of the reactants will ALWAYS equal the weight of the products.
How much matter is lost during a chemical changes?
No matter is lost during a chemical change. The mass of the products equals the mass of the reactants. The law of conservation of matter/mass states that in a closed system, matter is neither created nor destroyed.
How does a balanced chemical equation show that mass is never lost or gained in a chemical reaction?
Because the Balanced equation can correctly add the reactants and it will equal the sum of the products.If a chemical equation is balanced correctly, there will be the same number of each element on both sides. Since each element has a given and known mass, the total mass on each side of the balanced equation must be equal.
How could you determine if the products of cellular respiration have less chemical potential energy than the reactants?
I lost you at how
Why is the total mass of the products of a chemical reaction is equal to the total mas of the reactants?
This isn't true. The mass of reactants will equal mass of products in a closed system where gasses cannot enter or escape, but the mass can decrease if a gas is formed that escapes into the atmosphere (for example, hydrogen from your reactants is transformed into hydrogen or oxygen gas which escape into the room) or even INCREASE of the reaction draws in gas from the atmosphere which is incorporated into the product. There might even be an increase in mass if water vapor from the air ends up entering into the reaction. The equation for the reaction will always balance because of conservation of mass, but where that mass ends up can mean that the final weights to NOT remain the same. A closed system doesn't allow for entry or exit of additional mass, but an open system might.
How does law of the conservation of mass apply to chemical reactions?
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction.
What is the reaction in which water is lost from the reactants?
dehydration
What law states that the mass can not be lost or gained in a chemical reaction?
The law of conservation of mass states that in a chemical reaction the mass of the reactants must equal the mass of the product.
