COCH. that is the answer,
At -55°,volume=590ml
At 30°,volume=?
;-55°=590ml
30°=V
V=30/-55×590ml
V=-321.82ml
but we don't have a negative volume so V=321.82ml
Answer:
A
Explanation:
Bohr proposed that an electron is found only in specific circular paths, or orbits, around the nucleus
pH = 4.82
[H⁺] = 1.5 × 10⁻⁵ mol·L⁻¹.
pH = -log[H⁺] = -log(1.5 × 10⁻⁵) = 4.82
Answer:
Subtract the mass of the CuSO4⋅ 5H2O from the mass of CuSO4 is the right one
