Answer:
it is a replacement reaction
Answer:
Cd° + H₂O => Cd(OH)₂ + 2e⁻ (Oxidation Half-Rxn)
Explanation:
Oxidation => Loss of e⁻
Reduction => Gain of e⁻
(o) (+4)(-2) (+2)(-1) (+2)(-1)
Cd° + NiO₂ + 2H₂O => Cd(OH)₂ + Ni(OH)₂
Cd° + H₂O => Cd(OH)₂ + 2e⁻ (Oxidation Half-Rxn)
NiO₂ + H₂O + 2e⁻ => Ni(OH)₂ (Reduction Half-Rxn)
Answer:
7.64 Moles
Explanation:
As we know one mole of any substance contains 6.022 × 10²³ particles (atoms, ions, molecules or formula units). This number is also called as Avogadro's Number.
The relation between Moles, Number of Particles and Avogadro's Number is given as,
Number of Moles = Number of Particles ÷ 6.022 × 10²³
Putting values,
Number of Moles = 4.60 × 10²⁴ Particles ÷ 6.022 × 10²³
Number of Moles = 7.64 Moles
The right subject for this question is physics.
To calculate the work you use the formula:
Work = force * displacement
Work = 2500 pounds * 30 feet = 75,000 pounds - feet
To calculate the power you use the formula:
power = work / time
Power = 75,000 pound - feet / 30 seconds = 2300 pound-feet / second.
