Answer: A chemical process must occur and then changes between the state of the reactants and the state of the products can be determined
Explanation: Enthalpy represents the sum of the energy of the system with the product of the pressure and volume of that system. As a thermodynamic property, it expresses the ability to release heat from the system. In fact, enthalpy tells us how much heat and work has changed during the chemical reaction under constant pressure. When measuring, measurements of the difference in enthalpy between the two states of the system is performed, before and after the chemical reaction, since total enthalpy can not be measured. This measurement of the enthalpy change can tell us, for example, whether the heat was released from the system during the reaction, or the system absorbed the heat.
Close all network ports, filter those you can't block
Firewalls are used to filter network traffic and are available as standard system software on most operating systems. Limit the openings hackers have to your server.
Answer:
Electrons can jump from energy level to energy level (for example energy level 1 to 2) but they can NEVER be found in between energy levels.
A. high potential energy and zero kinetic energy.
It gives off a certain colour because when the spectrum is combined........I'm not sure if that's write but i think it is.....not 100% sure tho
