Answer:

\boxed {\tt 2.71169355 \ mL}

Explanation:

Density can be found using the following formula:

d=\frac {m}{v}

Rearrange the formula for v. Multiply both sides by v, then divide both sides by d.

d*v =\frac {m}{v}*v

d*v=m

\frac{d*v}{d}=\frac{m}{d}

v=\frac{m}{d}

The volume can be found by dividing the mass by the density. The mass is 2.69 grams and the density is 0.992 grams per milliliter.

m= 2.69 \ g\\d= 0.992 \ g/mL

Substitute the values into the formula.

v=\frac{2.69 \ g}{0.992 \ g/mL}

Divide. Note that the grams, or g, will cancel each other out.

v=\frac{2.69}{0.992 \ mL}

v= 2.71169355 \ mL

The volume of the water is 2.71169355 milliliters.

Which of the following are always larger than the neutral atoms from which they are formed?
frosja888 [35]
<span>A. positive ions : Positive ions are formed when a neutral atom loses electrons. When neutral atoms lose electrons, the ions formed are always smaller than the neutral atoms.


B. negative ions : Yes. When the neutral atoms gain electrons to form negative ions, they always become larger, because the addition of one electron increases the electrostatic repulsion of the outermost electrons, forcing them to drift apart.


C. cations  No. Cation is the same that positive ion.

D. none of the above </span>

4. How is the coordination number determined?
balandron [24]
A coordination number can be determined by the usage of an atom towards a molecule from seeing how many numbers of atoms would have to be combined together in an atom.

kupik [55]

Answer: An atom in an excited state contains more of kinetic energy than the same atom in the ground state.

Explanation:

Kinetic energy is the energy acquired by an object due to its motion. And, thermal energy is the internal energy of an object arisen because of the kinetic energy present within the molecules of the object.

Potential energy is the energy acquired by an object due to its position.

The total energy present at the center of mass of an object is known as mass-energy.

So, when an atom gets excited then it means it is gaining kinetic energy due to which it moves from its initial position after getting excited.

Thus, we can conclude that an atom in an excited state contains more of kinetic energy than the same atom in the ground state.
