Answer:
no of moles = (mass) ÷ molar mass
you get the molar mass from the periodic table
n = 20.0g ÷ ( 149.09 g/mol )
= 0.134 mol
number of formula units = number of moles × (6.022×10^23)
= 8.07×10^22 units
number of hydrogen atoms in (NH4)3 PO3 = 12 × number of formula units
= 9.68×10^23 hydrogen atoms
They are attracted by the shared pair of electrons. One requires one more electron and the other atom shares one electron with the other, making the atoms come together and stay.
Intensive properties are the properties which values doesnt change with the amount of mass or material that you have, example density, melting point boiling point, molecular mass
Extensive are properties that depends of how much mass or material you have. Example: mass, number of moles, volume, pressure, number of students, population,
mass, volume, quantity (there is only one of each), color, reflect light, temperature, energy
Answer:
Weathering (breaking down rock) and erosion (transporting rock material) at or near the earth's surface breaks down rocks into small and smaller pieces. ... If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma).
