Answer:
C) It moves faster and collects more data
Explanation:
The SI unit for distance is metres - m.
The SI unit for speed or velocity is metres per second - m/s.
The SI unit for acceleration is metres per second squared. - m/s^2.
M(H2SO4)=n*M=4.75*98=465.5g
Remember that a cation will be smaller than its neutral atom, and an anion will be larger than its neutral atom. This would automatically eliminate answer choices A and D.
Also keep in mind that atomic radii decreases from left to right as you move along a periodic table. It also decreases from bottom up.
Atomic radii increases as you move from right to left and as you go from up to down.
As bromine is higher up in the periodic table than Iodine, it would have a smaller radius. Iodine would have a larger radius.
The correct answer is B. Br
