I hope that's help !
<span>The answer is C)
mechanical advantage (MA = slope/height)
here length of slope = 9Hheight = H so mechanical advantage = ---- 9H/H= 9

Synthesis reaction is a reaction where two or
more substances combine to form a new compound. <span>It
is a reaction which releases energy in the form of heat and light. Therefore,
it is an exothermic reaction. </span>From its the definition the correct answer is the third option where carbon dioxide and water combine to form carbonic acid.
