One times anything is the same number. 1 x 2900= 2900
Increase, because you need heat to melt a solid to a liquid, so the temperature will have to get greater.
Answer:
I think option A is right answer
Answer: Endothermic, 2.80 kJ
Explanation
Since this reaction absorbs heat, it is endothermic.
The energy absorbed per mole CO is 2.80 kJ and this reaction is already balanced. q= 2.80 kJ
Hope this helps:)
3/8 NA = 3/8 x 6.023 x 10^23 molecules of h2o
so, we can easily conclude that 1mole of CH4 gives 2mole of H2o
