Sloan [31]

Material from this sedimentary rock ever forms igneous rock, <u>Option D. Yes, if the sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form </u><u>igneous rock.</u>

Sedimentary rocks are shaped from pre-existing rocks or pieces of soon-as-dwelling organisms. They form from deposits that collect on this planet's floor. Sedimentary rocks regularly have special layering or bedding.

Igneous rock, or magmatic rock, is one of the 3 primary rock kinds, the others being sedimentary and metamorphic. Igneous rock is shaped via the cooling and solidification of magma or lava. The magma may be derived from partial melts of existing rocks in either a planet's mantle or crust.

Analyzing a specific reaction Consider the following reaction: 2Mg+O2→2MgO,rate=k[Mg][O2]2 Part A What is the overall reaction o
stepladder [879]

Answer:

3

Explanation:

Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.

The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.

Thus,

For the reaction:-

2Mg+O₂→2MgO

Rate  = k[Mg][O₂]²

Order w.r.t. Mg = 1

Order w.r.t. O₂ = 2

<u>So, order of the overall reaction = 1 + 2 = 3</u>
