Answer:
Convergent boundaries form when two crustal plates are colliding. ... The subducting plate is being recycled as it begins to melt at about 100 kilometers. The water soaked oceanic plate forms molten rock that collects in magma ... If the break is along hundreds of kilometers of fault line a megathrust earthquake occurs.
Explanation:
The primary colors are blue, red, and yellow.
Answer:
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

Answer:
53·32 g
Explanation:
<h3>Given the ΔH for the reaction is for 1 mole of benzene(C6H6) and 1 mole of benzene contains 78 g of benzene</h3>
So for 78 g of benzene ΔH of the reaction is 630 kJ
Let the weight of benzene that must decompose to transfer 430 kJ of heat be m g
∴ 78 ≡ 630
m ≡ 430
For 1 kJ of heat to be transferred the weight of benzene required is 78 ÷ 630 = 0·124 g
For 430 kJ of heat to be transferred the weight of benzene required is 0·124 × 430 = 53·32 g
∴ m = 53·32 g
∴ 53·32 grams of C6H6 must decompose according to the given chemical equation to transfer 430 kJ of heat
An element is made up of an atom, a molecule is a bunch of elements, and a comping is a bunch of molecules
