Decomposition is the reverse of combination. therefore decomposition reaction is a type of reaction where one reactants produces two or more reactants.
Answer:
the correct option is:
We only need one electron to achieve a noble gas configuration
Explanation:
Halogens have 7 valence electrons in their outer energy shell, so when reacting with another element they satisfy the octet rule.
Halogens show trends in their binding energy from top to bottom on the periodic table with fluoride showing minimal deviation. They are shown to have strong bonding energy with other atoms but weak interactions with the F2 diatomic molecule. This means that as you go down the periodic table the reactivity of the element decreases due to the increase in the size of the atom.
Halogens are highly reactive, so they can be harmful to biological organisms in sufficient quantities. Its high reactivity is due to the high electronegativity that its atoms present due to its highly effective nuclear charges.
Hey there!
Molar mass of O3 = 47.9982 g/mol
therefore:
1 mole O₃ --------------------- 47.9982 g
moles O₃ ---------------------- 24 g
moles O₃ = 24 x 1 / 47.9982
moles O₃ = 24 / 47.9982
moles O₃ = 0.500 moles
Hope this helps!
Answer:
We will Multiply the number of moles with Avagadro's number
So it will be (2.04×1023)×6.022×10^23
<h3>or 2.04×1023 NA</h3>
NA means Avagadro's number
