The answer would be option A which is the Earth’s Orbit
Answer:
-2m/s/s
Explanation:
Acceleration = change in speed / change in time
Change in speed = final speed - initial speed
In this case the change in speed was 10m/s - 30m/s = -20m/s
And change in time was 10 sec (within 10 sec)
Therefore acceleration = -20/10 = -2m/s/s
The acceleration is negative because the car slowed down (decelerated essentially) and the unit for acceleration is meters per second per second because it is the change in speed per second.
Hope this helped!
Answer:
SO₄²⁻(aq) +Sn²⁺(aq) +4H⁺ → H₂SO₃(aq) + Sn⁴⁺(aq) + H₂O
Explanation:
At first calculate the oxidation state of that element which undergoes oxidation as well as reduction.
for SO₄²⁻ the oxidation state of sulphur is +6 and H₂SO₃ the oxidation state of sulphur is +4
So balance equation is
(Reduction) SO₄²⁻ + 4H⁺+ 2e⁻ → H₂SO₃ + H₂O.........................................(1)
(oxidation) Sn²⁺ → Sn⁴⁺ + 2e⁻ .............................................................(2)
Adding equation 1 & 2
we get
SO₄²⁻(aq) +Sn²⁺(aq) +4H⁺ → H₂SO₃(aq) + Sn⁴⁺(aq) + H₂O
Answer:
Esta configuración electrónica pertenece al elemento, neón.
