D, I believe is the correct answer. Hope I answered your question, have a good day.<span />
C) because a new substance is formed
B) not sure but might be because the chemical properties of the substance has changed
Answer:
A) exothermic, δh is negative
B) endothermic, δh is positive
C) endothermic, δh is positive
Explanation:
And endothermic process absorbs heat from its sorrounding, cooling the sorrounding down. Whereas an exothermic process releases heat to its sorrounding raising the temperature of the sorrounding system.
Answer:
1/2mv^2 a(7.5 b(15 kg c(60 kg d(120 kg. nevermind i found the answer its (15 kg) because to solve for m its m= K2/v squared.
