A Chemical Reaction
Explanation:
There are 2 kinds of reactions physical and chemical. The digestion process often involves the use of digestive enzymes in your mouth and acid in your stomach.
Answer:
(C) The average molecular speed of ethane is equal to the average molecular speed of propanol.
Explanation:
When dealing with gases, you know that the temperature and speed are related. When held at a constant temperature, the speed is also held constant. We also know that ideal gases behave the same despite their identities.
Instability of an atoms nucleus can result from an excess of either neutrons or protons . So neutrons and protons .
I think the correct answer is b. Temperature is proportional to the average kinetic energy so when temperarure rises so will the average kinetic energy. I hope this helps. Let me know if anything is unclear.
