We have water and also we are the perfect distance away from the sun and the moon which is unlike any other solar system
Answer:
mass of substance =50.4 g
Explanation:
Using the density formula;
Density = mass of substance / volume of substance
Therefore, making mass subject of the density formula,
mass of substance = volume of substance / density of substance
volume of substance = 60.5 mL, density = 1.20 g/mL ( since common units of density is either g/cm³ or g/mL)
mass of the substance = 60.5 mL / 1.20 g/mL
mass of substance = 50.4 g
Answer:
Included in the Lewis definition of acids are the metal ions; the oxides of certain nonmetallic elements, such as sulfur, phosphorus, and nitrogen; substances able to donate hydrogen ions or protons; and certain solid compounds, such as aluminum chloride, boron trifluoride, silica, and alumina. ;)
The plum pudding model of the
atom by the scientist Sir Joseph John Thompson or J.J. Thompson. It was
theorized after the discovery that electrons are present in the atom. In this
model, the atom is composed mainly of electrons. It was describe as plum
pudding because the electrons are dispersed within the atom. John Dalton
discovered the atom. Ernest Rutherford discovered the half – life of an atom
and Neils Bohr explain the quantum mechanics. So the answer is J.J. Thompson.
