Explanation:
The highest number is the strongest base. Therefore the pH of 12 is the strongest base here (C).
The atomic number of Nickle is 28, so its electronic configuration in ground state is,
Ni = 28 e⁻ = 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d⁸
So, when Nickle looses two electrons it will attain +2 charge, remaining with 26 electrons as,
Ni⁺² = 26 e⁻ = 1s², 2s², 2p⁶, 3s², 3p⁶, 3d⁸
Ni looses electrons from 4s shell instead instead of 3d shell because the 4s shell electrons are at larger distance as compared to 3d, hence, felting less nuclear charge and easily lost.
Molecular wt if ethene = 28 g/mol
take 14 ÷ 28 = 0.5 mol
since there is a 1:1 ratio between ethene and ethanol one should produce 0.5 mol
MW ethanol = 46
0.5 × 46 = 23 g should be produced.
17.25/23 = 0.75 = 75% Percent yield
Answer:
F = ma or Force = mass x acceleration.
Explanation:
Newtons second law is about the force put onto an object. To find this you would use the formula:
Force is equal to mass times acceleration (F=ma)
Answer:
a supply of electric charges which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges.
