Answer:
Reduction
Explanation:
Gaining electrons means reduction. When the electrons are on the reactant side of the reaction, they are added to the other reactant. This indicates that the Sn^4+ is gaining electrons and is therefore reduced (reduction).
Explanation:
Below is an attachment containing the solution
An oxygen molecule at 25◦C has a speed of 1520 miles/hour.
<h3>Equation :</h3>
As we know
1 km = 1000 meter
So,
678 / 1000 = 0.678 km
And 1 mile = 1.6 km
So,
0.678 / 1.609 = 0.4213 miles
We know that 1 hour = 60×60 = 3600 sec
So,
1 sec = 1 / 3600
= 2.777 x 10⁻⁴ hour
Now finding speed,
speed = distance / time
speed = 0.4213 / 2.777 x 10⁻⁴
speed = 1520 miles/hour
<h3>What is speed ?</h3>
Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path. In other words velocity is a vector value, whereas speed is a scalar value.

Answer:
this is due to the motion of the air which is known as the wind, when it's blowing, all light objects are been held upright because the motion of the wind is very strong
