Answer:
The baseball is thrown twice as fast as the softball in the same direction.
Explanation:
Answer:
Ethyl acetate is a polar solvent.
Explanation:
As you can see, the image below shows the chemical formula of Ethyl acetate. This compound has two oxygen atoms, whose electronegativity is greater than that of the carbon atom to which they are attached, the dipole moment of this molecule is nonzero. This phenomenon causes this compound to form dipole-dipole bonds with other polar molecules. This also means that polar compounds can dissolve in Ethyl acetate.
The correct answer is A. A <span> sample of sodium hydroxide (NaOH) has a mass of 160.0 g which is equal to 4 moles of NaOH. TO calculate this, we use the relation of the molar mass given.
160.0 g NaOh ( 1 mol NaOH / 40.0 g NaOH ) = 4.000 mol NaOH</span>
