Mass of HCl=1190g soln ×37.7g HCl100g soln =448.6 g HCl.Calculate the moles of HCl . ...Calculate the molarity of the HCl.</span>
Answer:
Mass = Number of neutrons + Atomic number (aka number of protons)
Explanation:
Answer:
Lava is hot liquid rock. When lava flows over solid ground, the solid ground beneath it increases in temperature. What happens to the molecules in the solid ground when the temperature is increasing? The energy of the molecules in the ground decreases.
Answer: A.
Explanation:
Gravitational potential energy is due to the position of an object above Earth's surface. The object has the potential to fall due to gravity. Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height).
Weight= Mass
Height= Height
Hope this helps!
