Answer:
41.576 N
Explanation:
Resolving force in the inclined plane in the x and y directions gives us;
F_x = mg sin θ
F_y = mg cos θ
Thus;
F_x = 4.8 × 9.81 × sin 28
F_x = 22.106 N
F_y = 4.8 × 9.81 × cos 28
F_y = 41.576 N
We can use Newton's second law to find the normal force.. Thus;
N - F_y = 0.
Where N is normal force;
N = 41.576 N

Answer: C) KClO3 → KCl + O2
Explanation:
the equation has an unequal amount of oxygen.
you can confirm because all the other equations are balanced so the answer is c
