Answer:
powder
Explanation:
Between the powder and marble chips, the powder will have a larger surface area.
For the same masses of a solid substance in different forms such as lump, granules or powder, the smaller particle size of each form the larger the surface area.
Surface area increases from lumps to granules and them powder
A powder has the largest surface area and hence undergoes a more faster chemical reaction. Identify the ionic compound that can form between potassium as the metal and nitrogen as the nonmetal.

Solution
For motion at a constant speed, the formula can be used:
d = v x t or d = s x t
v = velocity
s = speed
1. s = d : t = 40 m : 20 s⇒ s = 2 m/s
2. d = s x t = 13 m/s x 10 s ⇒ d = 130 m
3. t = d : s = 63 m : 9 m/s ⇒ t = 7 s
4. d = s x t = 28 mph x 2 h ⇒ d = 56 mi
5. t = d : s = 24 mi : 153.6 mph ⇒ t = 0.15625 h
6. s = d : t =1296 mi : 18 h⇒ s = 72 mph
