Answer:
Hg(NO3)2 + Na2CO3 --> 2NaNO3 + HgCO3
The moles of disodium edta used is calculated using the below formula
moles =molarity x volume in liters
molarity=0.050m
volume in liters = 22/1000=0.022 L
moles is therefore= 0.022 x0.050 =1.1 x10^-3 moles of disodium edta
Answer:
Reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume)
Explanation:
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.
