HBr is the most powerful and dangerous acid .
Explanation:
A strong acid is one that instantly disunites or grants its protons in suspension. HBr is a strong acid. HBr is powerful than HCl or HF because the overlapping of a 1s-orbital and a 4p-orbital is surprisingly small, thus the binding is weak so splitting is very easy..
Answer:
From the object at higher temperature to the object at lower temperature
Explanation:
Heat corresponds to the transfer of thermal energy between two objects. Temperature gives a measure of "how much thermal energy an object has": the higher the temperature, the faster the molecules inside the object, the more thermal energy the object has. Therefore, an object at higher temperature has more thermal energy than an object at lower temperature, so the transfer of heat goes from the object at higher temperature to the object at lower temperature.
