Yes and no. Yes because most of the mass isn't a firecracker anymore, and no because mass is never lost or gained in a chemical reaction, which is what a firecracker explosion is. If you have a nuclear powered firecracker, however, it would be a definite yes because some mass would be converted into energy.
False It should read: The amount of matter in an object is its mass (not weight)
False
mass wasting changes the surface of the earth quickly
Mass is the amount of matter in an object. You cannot have mass-less matter. If you have matter, than it contains some amount of mass.
An electromagnetic apparatus for separating isotopes of uranium and other elements according to their masses, using the principle of the mass spectrograph. It lost me at 'mass spectrograph'.
No matter is lost when a firecracker explodes. When the gunpowder inside ignites, it turns rapidly into gases and powder residue. The paper shell is either burned or fragmented into fine particles.
No. The explosion of a firecracker is a chemicalexplosion. Matter is converted from one form to another; molecules, that is, the atoms in the molecules, rearrange themselves releasing energy. That's the blast and the light. But the total mass of the substances involved is carried over into the combustion byproducts. No mass is lost. Chemistry does not change the involved mass in a reaction. Only nuclear reactions cause change in mass. In chemical reactions, energy can be released or absorbed according to the reaction and the constituent substances involved.
False. Both mass and energy are conserved.
False. A brown dwarf is a failed star that cannot sustain nuclear fusion. When a star explodes it will leav behind either a neutron star or a black hole depending on its mass.
To calculate the percentage of mass lost for bicarbonates, you would first determine the initial mass of the bicarbonate compound. Then, subtract the final mass after the reaction or process from the initial mass to find the mass lost. Finally, divide the mass lost by the initial mass and multiply by 100 to get the percentage of mass lost.
False. You will have the same mass on our moon, but weigh 1/6th as much as on the Earth.
A Nova or a Supernova.
A supernova resulting in either a neutron star, or a black hole.
False
False
The lost mass (or mass defect) transforms into energy according to the law: E = mc2
False It should read: The amount of matter in an object is its mass (not weight)
