Answer: gravitational force
Why?: gravity will always <em>pull </em>and move things in this earth, even when it comes to projectiles, gravity will still be a major part in its movement. therefore, your answer would be gravitational force! i hope this helped you!
Answer:
280 g Al₂O₃
Explanation:
To find the mass, you need to multiply the given value by the molar mass. This will cause the conversion because the molar mass exists as a ratio; technically, the ratio states that there are 101.96 grams per every 1 mole Al₂O₃. It is important to arrange the ratio in a way that allows for the cancellation of units. In this case, the desired unit (grams) should be in the numerator. The final answer should have 2 sig figs to reflect the given value (2.7 mol).
Molar Mass (Al₂O₃): 101.96 g/mol
2.7 moles Al₂O₃ 101.96 g
------------------------ x ------------------- = 275 g Al₂O₃ = 280 g Al₂O₃
1 mole
The correct answer is Carbon Dioxide.

What are carbon bonds?</h3>
- Because each carbon is identical, they all contain four valence electrons, so they can easily bond with different carbon atoms to form extended chains or rings. A carbon atom can bond with another carbon atom two or three times to create double and triple covalent adhesives between two carbon atoms.
- The partial payments on the fluorine and carbon are beautiful, contributing to the unusual bond power of the carbon-fluorine bond. The bond is marked as "the strongest in organic chemistry," because fluorine forms the strongest single bond to carbon.
- In chemistry, a covalent bond is the strongest bond. In such bonding, every two atoms transfer electrons that bind them concurrently. For example, water molecules are bonded jointly where both hydrogen atoms and oxygen atoms transfer electrons to form a covalent bond.

Answer is: near equivalence point indicator should change color, so we must pick indicator who changes color near pH of equivalence point.
Equivalence point is
the point which there is stoichiometrically equivalent amounts of acid and
base. <span>
<span>Chemist can draw pH curve (graph
showing the change in pH of a solution, which is being titrated) for
titration and determine equivalence point.</span></span>
