first there is only 25 points on here because if you add 50 points to the question brainly divides it by two so that two people can answer so if you want each person to get 50 points or to advertise how much point sis on this quetstion you would instead need to add 100 points to the question- anyways let's answer this question now
Do you know what the Law of Conservation of mass says? Matter is neither created nor destroyed. Therefore, you have started with 12.7 g Cu and 3.2 g S on the left for a total of 15.9 g; therefore, you must obtain 15.9 g of product(s). If Cu2S is the only product there must be 15.9 g Cu2S.
Crust
Core
Explanation:
For any terrestrial planet, the crust would be the coolest layer and the core would be the hottest layer.
Terrestrial planets or the inner planets made up rocky balls. They have layers that are differentiated.
Typically, they are made up of crust, mantle and the core.
The crust is the outermost layer.
The mantle is the middle layer and core is the inner most layer.
