The answer is D. If you aren't consistent with your drop positions, then your data may be invalid. To be frank: it basically screws over the experiment.
C. Generally, gravity is the only force acting on a projectile (causing it to fall down towards the earth). If you took this away, it would have no forces acting on it and, according to Newton's 1st law of inertia, it would continue moving indefinitely
I think the correct answer should be B<span>a(ClO3)2 = BaCl2 + 3O2. In balancing chemical reactions, it important that the number of atoms of each element in each side of the reaction should be the same. Hope this answers the question. Have a nice day.</span>
The density of the substance is obtained by dividing its mass by its volume. Density is an intensive property which means that its value does not depend on the amount of substance and will always stay the same for same conditions.
d = 84.7 g / 46.7 cm³ = 7.75 g / x cm³
The value of x is approximately 4.27 cm³.
