I THINK that that is true. It's just weathering the rock down not change composition. Lemme know if you get it right please! (:
Explanation:
1. subatomic particles.
2.proton, electron and neutron
3.The atomic mass of an element is actually the sum of the MASSES of protons and neutrons in AN atom of that element
4.An element's atomic number is equal to the number of protons in the nuclei of any of its atoms
5. Number of Protons = Atomic Number
Number of Electrons = Number of Protons = Atomic Number
Number of Neutrons = Mass Number - Atomic Number
For krypton:
Number of Protons = Atomic Number = 36
Number of Electrons = Number of Protons = Atomic Number = 36
Number of Neutrons = Mass Number - Atomic Number = 84 - 36 = 48
6. electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg
7.The center of the atom is called a nucleus
8. Negatively charged particles are found in multiple layers outside the nucleus of the atom. These particles are called electrons, and they orbit in various energy levels around the atom's nucleus.
9. A charged particle is also called an ion
B: nothing the color of the solution when heated
Answer:
The law of conservation of mass was obeyed since some of the mass evaporated while the cookies were baking.
Explanation:
Maria mixes water, flour, sugar, baking powder, butter and chocolate chips and then measures the mass of her ingredients.
Initial mass of ingredients = 1053 g
Final mass = 845 g
All these information are not of any great help.
Law of conservation of mass states that:
For any system closed to all transfers of matter and energy, the mass of the system can not change with respect to time, as system's mass cannot change, any mass can neither be added nor be removed.
In this process of baking, considering the cookies as our system, they never formed a closed system. Hence were free for evaporation.
During the process of baking, water from dough must have evaporated and mass must have reduced.
Hence, the law of conservation of mass was not obeyed.
The answer is C2O.............
