Hope it helped
Answer:
Explanation:
Speed is distance covered per unit time.it is a scaler quantity. It unit is m/s.
Velocity is speed in a given direction.it is a vector quantity. It unit is m/s.
Acceleration is the rate of increase in velocity.it is a vector quantity.it unit is m/s^2
The amount of the magnesium in the sample in ppm is 497 ppm.
<h3>What is parts per million?</h3>
The term parts per million refers to one of the manners in which concentration is expressed. It is common in oceanography and analytical chemistry.
Given that;
Mass of Mg= 0.0549 g
Mass of the sample = 110.52 g
Amount in PPM = 0.0549 g/110.52 g * 10^6
= 497 ppm

This is an oxidation reaction. The balanced equation is as follows:
6H₂O + N₂ → 2NO₃⁻+ 12H⁺ + 6e⁻
Rules to balance redox reaction in acidic medium
- Write the given equation in ionic form
- Identify elements undergoing oxidation ( charge increase, O.N inc) and reduction (charge dec, O.N dec)
- Break the equation into two halfs
- Balance the half equations
A. Balance all other atoms except Oxygen and hydrogen
B. Balance oxygen by adding H2O to the side deficient in oxygen
C. Balance hydrogen by adding H+ ions
D. Balance charge by adding electrons
5. Add the two half such that electrons gets cancelled
Oxidation number of N in N2 is 0 while in NO₃⁻, it is +5. Thus there is an increase in oxidation number, thus oxidation is taking place.
N₂(g) → NO₃⁻(aq)
N₂ → 2NO₃⁻
6H₂O + N₂ → 2NO₃⁻
6H₂O + N₂ → 2NO₃⁻+ 12H⁺
- balance charge. 0 charge on left, -6 and + 12 on right. add 6e⁻ on right to balance.
6H₂O + N₂ → 2NO₃⁻+ 12H⁺ + 6e⁻
Thus we can conclude that since there is increase in oxidation number, oxidation is taking place.
