Answer:
E. 16.6 mol HCl
Explanation:
The equation for the reaction is;
Zn + 2 HCl --> ZnCl2 + H2
From the reaction 2 moles of HCl produces 1 mole of ZnCl2
Therefore; 8.3 moles of ZnCl2 will be produced by;
= 8.3 moles ×2
= 16.6 Moles of HCl
Therefore; E. 16.6 mol HCl

Since the Summer solstice is when the sun is highest in the sky and the solstice is in June, that's your answer :)
Answer:
Explanation:
Heat involved Q = mcΔt where m is mass , c is specific heat of water and Δt is rise in temperature
= 150 x 4.18 x 25.8 J .
= 16176.6 J .
As the temperature rises , the reaction is exothermic.
