For the reaction c2h6 (g) → c2h4 (g) + h2 (g) δh° is +137 kj/mol and δs° is +120 j/k ∙ mol. This reaction is <span>spontaneous only at high temperature.
here the values of </span>δh° is +137 kj/mol and δs° is +120 kj/mol. so, both the value are wit the sign "+". when both values are positive than the reaction is not spontaneous at low temperature, the reaction is spontaneous only at high temperature.
Answer:
I thing Calcium Perchlorate
The answer is false because clay have more silt and sand
Answer:
Fluorine is more electronegative than iodine because atom size of F is less than I so the tendency to attract electron increases.
