The chemical symbol used is 2K + 2I to complete the equation for the decomposition reaction.
<h3>
What is decomposition reaction?</h3>
Decomposition reaction is defined as a chemical reaction when the reactant or molecule breaks down into less complex compounds Consequently, when a single reactant splits into two or more products. Because two or more reactants are combined to create a single product in a combination reaction, they are known as the opposite of a combination reaction.
One reactant produces two or more products during a decomposition process. Iodine and potassium will be produced as potassium iodide breaks down. With two K and two I on each side, this equation is balanced. It can be described using the all-inclusive formula: AB --> A + B.
Thus, the chemical symbol used is 2K + 2I to complete the equation for the decomposition reaction.

Answer:
atomic mass (12.0 grams) of carbon is equal to exactly 1 mole of carbon.So the Ans is Carbon
Explanation:
A. Haha at least need to be 20 words so yeah
Answer:
<em> 17.656 m</em>
<em></em>
Explanation:
Initial speed u = 20 m/s
angle of projection α = 60°
at the top of the trajectory, one fragment has a speed of zero and drops to the ground.
we should note that the<em> top of the trajectory will coincide with halfway the horizontal range of the the projectile travel. This is because the projectile follows an upward arc up till it reaches its maximum height from the ground, before descending down by following a similar arc downwards.</em>
<em></em>
To find the range of the projectile, we use the equation
R =
where g = acceleration due to gravity = 9.81 m/s^2
Sin 2α = 2 x (sin α) x (cos α)
when α = 60°,
Sin 2α = 2 x sin 60° x cos 60° = 2 x 0.866 x 0.5
Sin 2α = 0.866
therefore,
R = = 35.31 m
<em>since the other fraction with zero velocity drops a top of trajectory, distance between the two fragments assuming level ground and zero air drag, will be 35.31/2 = 17.656 m</em>
Answer:
The angular acceleration is final angular speed is
Explanation:
Here we know that
.............. 1
Upon substituting these values in equation 1 we get .
For calculating angular velocity we know that
.
