When 0.511 g of sodium metal is added to an excess of hydrochloric acid, 5310 j of heat are produced. what is the enthalpy of the reaction as written?

The the enthalpy of the reaction is 241.36 KJ.

Explanation:

Given that,

Weight of sodium = 0.511 g

We need to calculate the number of moles

Using formula of moles

We need to calculate the energy in 1 mole

In 0.022 moles of sodium metal = 5310 J

In 1 moles of sodium metal =

The Energy in 1 moles of sodium is 241363.63 J.

Hence, The the enthalpy of the reaction is 241.36 KJ.

lexy is right because she has the labeled s

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
