0.65×100=65g
100 is the mass of one mole of caco3 in grams.
Answer:
The mass of PCl₃ is 332.3 g.
The molecules of PCl₃ is
Explanation:
Given that,
Mass of P₄ = 75.0 g
Mass of Cl₂ = 275 g
We know that,
The reaction is
We need to calculate the moles of P₄
Using formula of moles
Put the value into the formula
We need to calculate the moles of Cl₂
Using formula of moles
Put the value into the formula
We need to calculate the number of moles of
Moles in 1 P₄ = 0.61
So,
We need to calculate the mass of
Using formula of mass
Put the value into the formula
We need to calculate the molecules of
Using formula of molecules
Where, n = number of moles
N = avagadro number
Put the value into the formula
Hence, The mass of PCl₃ is 332.3 g.
The molecules of PCl₃ is
Iron Fluoride
A chemical compound is a substance composed of atoms from two or more (different) elements. These compounds are formed by the creation of chemical bonds between the atoms of the different elements.
Helium and Neon are both elements, and in particular, they belong to a group of chemical elements called noble gases. Being noble gases, they are very stable and do not react easily.
Iron fluoride is a chemical compound consisting of the metal, iron, and the nonmetal, fluorine. When a metal and a nonmetal react to form a compound, they form ionic bonds to hold together the atoms of the different elements comprising the compound.
K2SO4 MgSO4 Al2(SO4)3 Ge2(SO4)4
KNO3 Mg(NO3)2 Al(NO3)3 Ge(NO3)4
KCH3COO Mg(CH3COO)2 Al(CH3COO)3 Ge(CH3COO)4
Note: all of the numerical are subscript to each element or compound.
Answer:
anciet fossils
Explanation:
Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content. Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.
