Na₃PO₄ -----> 3Na(+) + PO₄(3-)
y-y.......................3y...........y
3y = 1.2
y = 0,4M
Na₃PO₄ -----> 3Na(+) + PO₄(3-)
0,4-0,4..............1,2..........0,4
0.........................1,2..........0,4
C = n/V
n = C×V
n = 0,4×0,65L
n = 0,26 mol Na₃PO₄
mNa₃PO₄: (23×3)+31+(16×4) = 164 g/mol
164g ----- 1 mol
Xg -------- 0,26 mol
X = 164×0,26
X = 42,64g Na₂SO₄
Answer: 1) p⁺ = 22; number of protons.
e⁻ = 19 - 1 = 18; number of electrons.
Net charge is +4, because atom has 4 protons more than electrons.
Proton is a subatomic particle with a positive electric charge of +1e elementary charge.
2) p⁺ = 22; number of protons.
e⁻ = 19 + 3 = 22; number of electrons.
Net charge is 0 (neutral charge), because atom has same number of protons and electrons.
Hope this helps :)
Answer:
Blues
Explanation:
Colors of Rainbow => ROYGBIV
Red Orange Yellow Green Blue Indigo Violet
low energy => => => => => => => => => => high energy
low frequency => => => => => => => => => high frequency
long wavelengths => => => => => => => => short wavelengths
Note: All L's on the Left => low, low, long; other end are opposites.
