Answer:
4.24m/s,45 degrees in forward direction
Explanation:
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.
