1. Rocks near mid-ocean ridge were younger than rock near trenches
2.Matching bands of magnetic rocks were found on either side the mid-ocean ridge; bands like tree rings - record changes in earth's magnetic field over time
3. Earthquake data showed oceanic crust is sinking on to the mantle at trenches

Answer:
Explanation:
The mechanism of the reaction is shown in the diagram below. From the reaction, when (2S,3S)-2-Bromo-3-phenylbutane undergoes a reaction with sodium ethoxide (ETONa), the E2 elimination reaction is put into place. Here, the H and the leaving group are antiperiplanar to one another and the reaction mechanism proceeds to form an isomeric (E)-2-phenyl-2butane as the major product.
Answer:
Explanation:
T₁ = 100 + 273 = 373K
T₂ = 273 + 119 = 392 K
V₁ = initial volume
V₂ = Final volume
P₁ = P₁
P₂ = .85P₁
Using gas law equation
V₂ = 1.236 V₁
% increase in volume
= V₂-V₁ / V₁ x 100
= (1.236 V₁ - V₁ / V₁)x 100
= .236 x 100
= 23.6 % .
