Nuclear Fusion is when two atoms (usually Hydrogen and helium because they are very light and abundant) are smashed together to form heavier elements and in the process releases massive amounts of energy. Nuclear Fission on the other hand is when a heavier atom is split apart at the nucleus and releases large amounts of energy and free neutrons and photons. (in the form of gamma rays)
Answer:
Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of Earth's lithosphere, since tectonic processes began on Earth between 3.3 and 3.5 billion years ago.
Answer:
C. NH₃
Explanation:
This buffer is formed by a weak base (NH₃) and its conjugate acid (NH₄⁺) which comes from the salt NH₄Cl. When an acid is added (hydrobromic acid) it is neutralized by the basic component of the buffer, according to the following equation.
NH₃(aq) + HBr(aq) ⇄ NH₄⁺(aq) + Br⁻(aq)
Answer:
(f - g)(2) = -6
Step-by-step explanation:
(f - g)(2) = (-2x + 8) - 5x, where x=2
= (-2(2) + 8) - 5(2)
= (-4 + 8) - 10
= 4 - 10
= -6
(f - g)(2) = -6
