Hess's law ____. A) makes it possible to calculate ΔH for complicated chemical reactions B) states that when you reverse a chemical equation, the sign of ΔH does not change. C) determines the way a calorimeter works D) describes the vaporization of solids

Answers

A.)   makes it possible to calculate ΔH for complicated chemical reactions 

Hess’s Law makes it possible to calculate ΔH for complicated chemical reactions. Moreover, the principle claims that the entire amount of “enthalpy” when the development or progression of a chemical reaction is complete whether the reactions are created in a single or numerous processes, it still changes. This law is now described as the principle of conservation of energy, and part of the thermodynamics law as the first.

select all the correct answers. Which conditions are required for nuclear fusion to begin? The gas cloud must be very dense. Gravitational attraction must stop. Atoms must be stripped of their electrons. Helium atoms must break down into hydrogen. Temperatures must exceed 14 million Kelvin.

Answers

Nuclear fusion is the process in which atomic nuclei come together to form heavier nuclei, releasing large amounts of energy in the process. The correct statements are The gas cloud must be very dense, Atoms must be stripped of their electrons, and Temperatures must exceed 14 million Kelvin.

For fusion to occur, certain conditions must be met. The gas cloud or plasma must be dense enough to allow for a sufficient number of collisions between atomic nuclei. Gravitational attraction, on the other hand, is necessary to bring the atomic nuclei close enough together for the strong nuclear force to overcome the electrostatic repulsion between positively charged nuclei.

Atoms must be stripped of their electrons because, in a plasma state, the atoms are ionized, meaning they have lost or gained electrons and exist as charged particles.

Hence, the correct statements are The gas cloud must be very dense, Atoms must be stripped of their electrons, and Temperatures must exceed 14 million Kelvin.
