D= mass over volume
So, density equals 9.0g divided by 45ml.
SO, D=.25 g/ml
I'm not 100% sure this is correct, though. Best if luck. ♡
Answer:
100 mL is the volume of HCl needed to neutralize the 44.3 of Ba(OH)₂
Explanation:
This is the chemical equation:
2HCl + Ba(OH)₂ → BaCl₂ + 2H₂O
Formula for neutralization is:
Molarity of acid . Volume of acid = Molarity of base . Volume of base
0.121 . Volume of acid = 0.274 . 44.3
Volume of acid = (0.274 . 44.3) / 0.121 → 100
CuCO₃ ---T--> CuO↓ + CO₂ ↑
CO₂ escapes to the atmosphere (it's a gas)
Answer:
Explanation:
given data
we will take here
sodium ions = positive charge
chloride ions = negative cgarge
solution
as when we take Na positive charge so Number of origin is
d = 0
and here pair of ions with negative charge at d = - r
and d = +r
therefore
we will use here Taylor series approx method
and N/2 pair will contribute here
so
so energy per ion will be here
