The heat released by reaction : C) -8870 J
<h3>Further explanation</h3>
Given
1.008 g of hydrogen
500.00 g water
The temperature rises 25.00 °C to 29.24 °C
Required
energy required
Solution
Q absorbed by water :
Q = m.c.Δt
Q = 500 g x 4.18 J/g C x (29.24-25)
Q = 8870.08 J
The reaction to produce HCl is an exothermic reaction (releasing heat), so that Q is negative
Q water = -Q HCl = -8870.08 J

ohh im not sure but i think its A
the awnser is 87 hope this helped
An Environmental Impact Study is used to provide a sufficient level of detail to demonstrate that a proposed development will have no negative impacts on the natural features or ecological functions of the subject and surrounding (“adjacent”) lands. Hope this helps!!!
