No as oxygen is not balance
In reactants side there is 12 oxygen and in the product side there is 8 oxygen
Antimony cannot be broken down by chemical means because it is an element, a principle building block of matter. All other choices are compounds, which can be separated if put through enough stress to break the bonds between the atoms.
The process that is responsible for building successive fossils layers on earth is called DEPOSITION.
Deposition refers to the process by which sediments are added to a particular land form. There are different types of sediments and they are made up of different elements. A sediment can be in form of rocks and mineral debris, a precipitate formed from dissolution of a mineral in water or remains of other plants and animals. As these sediments are added to the foundational fossils layers, they form deposits which result in building up of successive layers.<span />
Aluminium is overall more reactive because it can loose electrons easier and therefore in a displacement reaction can force electrons upon less reactive metals such as chromium
Density=mass/volume so mass=density/volume mass=500ml/1.43g/ml mass=0.00286
