I believe the answer is C: "<span>It occurs when a hydrogen atom bonds with electropositive atoms."</span>
If you are talking about at the beaches waves would cause increased abrasion because the force of a wave hitting a rock or something else will slowly cause the object to wear away. Also strong winds could cause increased abrasion because the wind could pick up small sand particles that will slowly erode the thing it hits.
1) N = 4,2 moles
M = 24,31 u
m = N x M
= 4.2 x 24.31 = 102.102 kg
2) m = 54.9 grams = 0.0549 kilograms
M (Na) = 22.99 u
N (moles) = m / M
N = 0.0549 / 22.99 = 2.4 x 10^-3 moles
I don’t know if it helped you a bit :)
