please give me brainliest
D because that is something that can be tested an get a actual answer. All other answer choices are opinions and change based on people’s views of that object
Answer:
Explanation:
Hello!
In this case, for such calorimetry problem, we can notice that the combustion of the compound releases the heat which causes the increase of the temperature by 11.95 °C, it means that we can write:
In such a way, we can compute the total released heat due to the combustion considering the calorimeter specific heat and the temperature raise:
Next, we compute the molar heat of combustion of the compound by dividing by the moles, considering 1.400 g were combusted:
Thus, we obtain:
Best regards!
Answer:
The following reaction will occur at cathode:
Explanation:
The two half reaction during electrolysis of aqueous nickel sulfate will be
a) anode reaction :
Water will undergo oxidation and will evolve oxygen gas at anode as shown in the given reaction:
b) Cathode reaction: The reduction of Nickel ion will occur by gain of two electrons as shown in the given equation:
Thus the overall reaction will be:
