Gravity force is at least partially responsible for changing the energy of an object pushed off an edge.
Explanation:
- Gravity or gravitation, it is a phenomenon by the things with mass or energy including stars, galaxies, planets, and even light are taken to one another.
- The gravitational pull of the Universe's initial gaseous matter caused it to begin to coalesce and form stars, which caused the stars to gather together into galaxies, and gravity is responsible for all of the Universe's large-scale structures.
- Gravity has an unlimited range, but its effects are becoming ever weaker as items get away further.
Answer:
A, B, C and D
Explanation:
It can result for all of the choices mentioned.
Answer:
The first molecule Avogadro constant is given as 6.022 X 10∧23/ mol
Explanation: Avogadro constant is the constituent particles of molecules, atoms and ions that make up a mole of an element or compound. Therefore, CO2 comprises one molecule, which is equivalent to 6.022 X 10∧23/ mol.
Answer:
No effect will be observed.
Explanation:
Let´s consider the following reaction.
CuS(s) + O₂(g) ⇋ Cu(s) + SO₂(g)
<em>What effect will reducing the volume of the reaction mixture have?</em>
We need to take into account Le Chatelier's Principle: if a system at equilibrium suffers a perturbation, it will react to counteract that perturbation. According to Boyle's Law, if the volume is reduced then the pressure increases. According to Le Chatelier's Principle the system will try to reduce pressure by shifting the equilibrium towards where there are fewer moles of gases. In this case, there is 1 mol of gases on the left side and 1 mol of gases on the right side. That´s why no effect will be observed.
I think the correct answer would be false. <span>Gases do expand because they do not have an absolute volume. However, liquids do not expand to fill their container, they just fill and follows the shape of the container. Hope this answers the question.</span>
