Answer : The oxidation state of Mg in Mg(s) is (0).
Explanation :
Oxidation number or oxidation state : It represent the number of electrons lost or gained by the atoms of an element in a compound.
Oxidation numbers are generally written with the sign (+) and (-) first and then the magnitude.
Rules for Oxidation Numbers are :
The oxidation number of a free element is always zero.
The oxidation number of a monatomic ion equals the charge of the ion.
The oxidation number of Hydrogen (H) is +1, but it is -1 in when combined with less electronegative elements.
The oxidation number of oxygen (O) in compounds is usually -2.
The oxidation number of a Group 17 element in a binary compound is -1.
The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.
The given chemical reaction is:
In the given reaction, the oxidation state of Mg in Mg(s) is (0) because it is a free element and the oxidation state of Mg in is (+2).
Hence, the oxidation state of Mg in Mg(s) is (0).
A=dv/ dt
a=(v2-v1)/(t2-t1)
a=(60-50)/(10-0)
a=10/10
a=1
it's acceleration is 1 km/s^(2) or 1000 m/s^(2)

Answer: -
Thus ¹³C ⁻ ion has 7 electrons, 7 neutrons and 6 protons.
Explanation: -
The mass number for ¹³C = 13
The atomic number for ¹³C = 6
Number of electrons present in ¹³C = atomic number = 6
Number of protons present in ¹³C = atomic number = 6
Number of neutrons present in ¹³C = mass number - atomic number = 13 - 6 = 7
For ¹³C ⁻ ion,
Number of electrons present = 6 + 1 = 7
Thus ¹³C ⁻ ion has 7 electrons, 7 neutrons and 6 protons.
Because you introduce two reactants, causing them to produce a new chemical product. :)
PH + pOH = 14
pH = 14 - pOH = 14 - 2 = 12
A pOH of 2 is equivalent to a pH of 12. A pH greater than 7 is basic, and 12 is greater than 7. Therefore, a solution with a pOH of 2 is basic.
Thus, the correct answer choice is B.
