atoms consist of protons and neutrons in the nucleus , surrounded by electrons that reside in orbitals . Orbitals are classified according to the four quantum number s that represent anyone particular orbitals energy , shape , orientation and the spin of the occupying electron.
hope this helps xx
Explanation:
We can summarize the reaction shown as:
2F₂ + I₂ → 2F₃I
Since I is purple
F is the green
The number of I atoms in the reactants is greater than the number in the product
False:
The number of I atoms on both side of the expression is 2
There are 4 atoms of F in both the reactants and the products.
False:
There are 4 atoms of F on the reactant side and 6 atoms of F on the product side
The illustration represents a valid chemical transformation. True or false
False
The reaction does not represent a valid chemical transformation because in a valid chemical transformation, the number of atoms on both sides of the expression must be the same.
First we convert kg to g
1kg =1000g
4.70=x(gram)
4.70×1000÷1=4700g
now:
number of moles=mass÷molarmass
number of moles=4700÷65.4
number of moles=71.86moles.
Convert mole to gram by multiplying the molar mass of sodium
0.500mol Na x 22.990g = 11.495g of Na
