When metamorphic rocks are exposed to the earths surface they will be broken down into tiny fragments or pieces.Those are called sediments and after the tiny rocks are compacted against each other ,they will become sedimentary rocks .Hope this helped !
<span>Endothermic Reaction. This reaction or process absorbs energy from its surroundings, mostly, but will not always be, in form of heat. A reaction that requires the input of energy that breaks a bond will always be endothermic. Best examples of endothermic reaction are: 1) melting cubes; 2) evaporating of liquid; 3) melting solid salts, etc.</span>
Answer:
exothermic, with a decrease in entropy
Explanation:
Whenever you produce heat as a product in a reaction, the reaction is exothermic. To determine entropy, we know we have 4 moles of gas on reactant (1 from N2 and 3 from H2) and in produce side we only have two moles (2 from NH3) thus since we are decreasing the number of gas molecules, there is going to be less disorder, hence decrease in entropy.
The sum of the mass numbers and the sum of the atomic numbers balance on either side of an equation
Double replacement. It is normally described as AB+CD=AD+CB.
Hope this helps!! (:
