Answer:
There are four laws of thermodynamics that define fundamental physical quantities (temperature, energy, and entropy) and that characterize thermodynamic systems at thermal equilibrium.
Explanation:
3NH4OH+AlCl3=Al(OH)3+3NH4Cl
The temperature is the same but the heat flow is the opposite.
Answer:
Your stomach lining also secretes hydrochloric acid, which creates the ideal conditions for the protein-digesting enzymes to work. The potent hydrochloric acid kills bacteria, protecting your body from harmful microbes which can enter your body in food.
