Explanation:
The most reactive metals are found on the left of the periodic table, in the blue column, known as the alkali metals. Their reactivity increases as we go down column (group) one. Reactive metals, when attached to less reactive metals, have the ability to prevent the less reactive metal from rusting.
Answer:
From the given variable values, we can calculate the density of the rock sample to be = 10750_Kg/m^3
Explanation:
To solve this question, we recollect that density is the mass per unit volume of a substance and the SI unit of density is Kg/m^3 with symbol
ρ
The given variables are as follows
mass of rock sample = 8.6g
The volume displaced in the graduated cylinder is
(Final volume level of the cylinder) - (initial volume level of the cylinder)
13.6ml - 12.8 ml= 0.8ml = volume of the rock sample
Therefore, density = 8.6/0.8 = 10.75g/ml = or 1000×10.75 Kg/m^3 =10750Kg/m^3
Density of the rock sample is 10750Kg/m^3
Periodic table is arranged according to atomic size and other properties.
Humus forms when plant and animal matter decay and particle size have different elements such as clay and sand with sand being the biggest
Answer:
The Pauli Exclusion Principle states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
