An atom in an excited state contains more of what type of energy than the same atom in the ground state? An atom in an excited s

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.

A chemist must prepare 300.0mL of nitric acid solution with a pH of 0.70 at 25°C. He will do this in three steps: Fill a 300.0mL

d1i1m1o1n [39]

Answer: The volume of concentrated solution required is 9.95 mL

Explanation:

To calculate the pH of the solution, we use the equation:

$pH=-\log[H^+]$

We are given:

pH = 0.70

Putting values in above equation, we get:

$0.70=-\log[H^+]$

$[H^+]=10^{-0.70}=0.199M$

1 mole of nitric acid produces 1 mole of hydrogen ions and 1 mole of nitrate ions.

Molarity of nitric acid = 0.199 M

To calculate the volume of the concentrated solution, we use the equation:

$M_1V_1=M_2V_2$

where,

$M_1\text{ and }V_1$ are the molarity and volume of the concentrated nitric acid solution

$M_2\text{ and }V_2$ are the molarity and volume of diluted nitric acid solution

We are given:

$M_1=7.0M\\V_1=?mL\\M_2=0.199M\\V_2=350mL$

Putting values in above equation, we get:

$7.0\times V_1=0.199\times 350.0\\\\V_1=\frac{0.199\times 350}{7.0}=9.95mL$

Hence, the volume of concentrated solution required is 9.95 mL

In this item, we are simply to find the ions that may bond and are able to form a formula unit. We are also instructed to give out their name. There are numerous possible combinations of ions to form a compound. Some answers are given in the list below.

1. Na⁺ , Cl⁻ , NaCl ---> sodium chloride (this is most commonly known as table salt)

2. C⁴⁺ , O²⁻ , CO₂ ---> carbon dioxide

3. Al³+ , Cl⁻ , AlCl₃ ----> aluminum chloride

4. Ca²⁺ , Cl⁻ , CaCl₂ ---> calcium chloride

5. Li⁺ , Br⁻ , LiBr ---> lithium bromide

6. Mg³⁺ , O²⁻ , Mg₂O₃ ----> magnesium oxide

7. K⁺ , I⁻ , KI ---> potassium iodide

8. H⁺ , Cl⁻ , HCl --> hydrogen chloride

9. H⁺ , Br⁻ , HBr ----> hydrogen bromide

10. Na⁺ , Br⁻ , NaBr ---> sodium bromide
