What is the correct formula for Na+ and (SO4)2- ?
2 answers:
Answer:
A)Na2SO4
Explanation:
When reaction between NaOH and H2SO4 take place then Na2SO4 comes out as a product.
Na2SO4 is a salt .We know that when base and acid react then salt will produce as a product.
Na2SO4 is called sodium sulfate.
Two sodium ions and one sulfuric ions make sodium sulfate.

Internal thermal energy is given as
so it will depend on the product of mass, specific heat capacity and temperature.
so here we know that both blocks are identical with same initial temperature
So the block with larger mass must have more internal energy
So here the correct answer would be the block with mass 1000g
block with mass 1000 g must have more internal energy
