A chemical reaction is endothermic if it absorbs heat from its surroundings. It is exothermic if it gives off heat to its surroundings. In her chemistry class, Lily is given a salt (ammonium nitrate) and a beaker of water at 60 ∘F. She dissolves the salt in the water and sees that the temperature of the solution is now 50 ∘F. Did the temperature of the solution go up or go down? By how many degrees? What kind of reaction has occurred?

The temperature went down by 10 degrees F. An exothermic reaction happened because the temperature went down so heat was released.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

the answer is simply just 6n add the two together as they have an n
