Answer:
14.9 g Sb
Explanation:
The mass of Sb produced can be calculated using the conversion:
Molar Mass (g/mol) = mass (g) / moles
Antimony (Sb) has the molar mass 121.76 g/mol. This value is found on the periodic table. You have been given the moles produced. Therefore, you can find the mass of Sb by plugging these values into the formula and simplifying.
Molar Mass = mass / moles
121.76 g/mol = mass / 0.122 moles
14.9 = mass
where the Avogadro's constant that relates the number of particles to their number, in the unit moles .
The molar mass of propanol- mass per mole propanol- can be directly deduced from its molecular formula with reference to a modern periodic table.
of propanol molecules would thus have a mass of
Answer:
In a compound, chemical energy is _____required__________ when bonds break.
Color, phase, odor and boiling point are the physical properties. Reactivity with oxygen depends on the chemical nature of object, thus, it is not a physical property. It is a chemical property.
<span>Chemists considered Martian
Periodic Table as one of the most useful tools they’ve used whose purpose is to
arrange the Martian elements according
to their properties and their atomic number. On this periodic table, it was
found out that the properties seem to vary.
Dmitri Mendeleev, the first to arrange the periodic table according to
atomic mass in a manner that the elements with the same properties were grouped
together. It was Henry Moseley who later arranged the periodic table in accord
to the increasing number of atoms per element. </span>
