What else can I help you with?
Is this statement true or false When nuclear reactions happen the total amount of energy changes It is the mass plus energy before and after the reaction that are equal?
That is false. Assuming an exothermic reaction, e.g., a fusion of hydrogen to helium:The total amount of mass before and after the reaction is the same. (Any energy leaving the atom has a mass equivalent.)The total amount of energy before and after the reaction is the same. (The energy was there previously, in the form of potential energy).
Is a equation the symbolic representation of a chemical reaction based on the Conservation of Mass?
Yes, an equation is the symbolic representation of a chemical reaction that follows the law of conservation of mass. This means that the total mass of the reactants is equal to the total mass of the products in a chemical reaction.
Why should you balance chemical reaction?
Balancing a chemical reaction ensures that the same number of each type of atom is present on both sides of the equation, satisfying the law of conservation of mass. This is important because it reflects the true stoichiometry of the reaction and allows for accurate calculations regarding the quantities of reactants and products involved.
A nuclear reaction in which the nuclei of atoms join together is called nuclear fission.true or false?
False. Combining nuclei to form a new nucleus is called nuclear fusion. Nuclear fission is the splitting of an atomic nucleus.
True or false . The law of conservation of mass states that in a chemical read took matter is not created or destroyed?
True. The law of conservation of mass states that in a chemical reaction, matter is neither created nor destroyed; it simply changes form. This means that the total mass of the reactants equals the total mass of the products in a chemical reaction.
What is true is true regarding hydrogen fuel cells and hydrogen fuel cells and hydrogen fusion?
More mass is converted to energy in a fusion reaction than in a chemical reaction, such as that found in a fuel cell. - APEX
A balance is used to measure mass true or false?
True, the most common method is to use a balance
Which of the following is true regarding hydrogen fuel cells and hydrogen fusion?
The amount of mass that "disappears" in the fusion of two hydrogen atoms is more than the amount of mass that "disappears" when two atoms are used in a fuel cell.the amount of mass that dissapears.........ect
Is this statement true or false When nuclear reactions happen the total amount of energy changes It is the mass plus energy before and after the reaction that are equal?
That is false. Assuming an exothermic reaction, e.g., a fusion of hydrogen to helium:The total amount of mass before and after the reaction is the same. (Any energy leaving the atom has a mass equivalent.)The total amount of energy before and after the reaction is the same. (The energy was there previously, in the form of potential energy).
True or false balance scales are used to measure the mass of an object?
True. Balance scales are used to measure the mass of an object by comparing it to known weights on the other side of the scale until balance is achieved.
What metric units does a balance use?
A true balance measures mass, so grams or kilograms.
True or false The law of conservation of mass states that in a chemical reaction, matter can be created or destroyed?
False. The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. The total mass of the reactants must equal the total mass of the products.
Is a equation the symbolic representation of a chemical reaction based on the Conservation of Mass?
Yes, an equation is the symbolic representation of a chemical reaction that follows the law of conservation of mass. This means that the total mass of the reactants is equal to the total mass of the products in a chemical reaction.
According to the Law of Conservation of Mass in a chemical reaction the total starting mass of all the reactants equals the total final mass of all the products true or false?
False
How do you measure the mass of a cow?
Put her on a truck and have the truck weighed on a balance scale (NOT a spring scale). From this you can get true mass.
Does The Law of Conservation of Mass states that mass is conserved in a reaction system?
Yes, the Law of Conservation of Mass states that mass is conserved in a closed system, meaning that the total mass of the reactants must equal the total mass of the products in a chemical reaction.
What is true about matter during a chemical reaction the mass of the reactions is not related to the mass of the prroduct?
No. In a closed system, the mass of the products should equal the mass of the reactants.
