Number of Atoms in Methanol are calculated as,
Write chemical formula of Methanol,
CH₃-OH
Find out Subscripts:
There is only one subscript (₃) written after Hydrogen, it means there are 3 Hydrogen atoms attached to Carbon atoms.
Add all atoms in molecule:
Carbons = 1
Hydrogens = 4
Oxygens = 1
Total Atoms ______
6 Atoms
<span>Colligative properties are dependent upon the number of molecules or ions present in solution. Therefore, 1 mole of Na2SO4 will produce 3 moles of ions and so it will have 3 times as much of an effect as 1 mole of sugar, which is not an electrolyte and can't dissociate to an appreciable extent.</span>
Answer:
Magnesium has an outer energy level of n=3 with two electrons in in its energy level. Therefor Magnesium has 2 valance electrons.
Explanation:
<span>Alpha particle is nucleus
of a helium-4 atom, which is
made of two protons and
two neutrons.
Nuclear reaction: </span>₈₄²¹⁸Po → ₈₂²¹⁴Pb + α (alpha particle).<span>
Alpha decay is radioactive decay in
which an atomic nucleus emits
an alpha particle (helium
nucleus) and transforms into an atom with an atomic
number that is reduced by two and mass number that is reduced by four.</span>
