The amount of mass for each milliliter of a substance determines the substances?
No. There are many substances with identical densities.
What happens during fission and fusion reactions that results in the release of huge amounts of energ?
The total mass of the involved particles before either process happens is more than the total mass of the products after the either reaction happens. This is known as the mass defect of the system, Δm, and can be used to calculate the energy released via the equation E = Δmc2, where E is the energy and c is the speed of light.
How does the mass of the products in a chemical equation compare to the mass of a reaction?
In a closed system, the mass of the products equals the mass of the reactants.
Which equation correctly expresses the calculation of density?
Density is calculated by dividing the mass of an object by its volume. Mathematically, the equation for density is density = mass/volume.
What chemical equation is properly balance?
The reactants must be balanced correctly with reactants.
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.
What happens to the overall mass of a substance when it changes state?
the mass does not change because in science class today we learned when you measure an ice cube (mass) it is the same mass of ice melted!
A balanced chemical equation allows you to determine the?
mole ratio ofany two substances in the reaction
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.
Why is force needed?
Force happens when an object of mass is accelerated, and the equation to calculate force is : force=mass/acceleration
How can you calculate the density of substances using an equation?
density = mass/volume If you can measure the mass (amount of matter) and volume (how much space it takes up), use that to calculate the density.
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
When substances go through a chemical change what happens to the mass'?
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.
The equation of atomic mass?
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Equation for mass?
mass
Whats the equation for mass?
One equation is Force/acceleration=mass
What happens to the total mass of substances during a chemical reaction?
During a chemical change,chemical energy may be changed to other forms of energy.other forms of energy may also be changed to a chemical energy.
