Answer:

Exercise: The easiest and most effective way to achieve a lasting lower heart rate is to do regular exercise. 2. Stay hydrated: When the body is dehydrated, the heart has to work harder to stabilize blood flow. Throughout the day, drink plenty of sugar- and caffeine-free beverages, such as water and herbal tea.

Energy Levels: An ionized atom having Z protons has had all but one of its electrons removed. If E is the total energy of the gr
S_A_V [24]

Explanation:

Formula for energy value is as follows.

                     E = \frac{-E_{0}}{n^{2}}

where,      E_{0} = 13.6

                         n = number of shell                          

So, at ground state energy  of hydrogen atom will be as follows.

                    E = \frac{-E_{0}}{n^{2}}

                       = \frac{-13.6}{(1)^{2}}

                      = -13.6

Hence, for an ionized atom value of energy will be as follows.

                    E' = -13.6 \times Z^{2}

    or,            E' = E \times Z^{2}

Thus, we can conclude that total energy of the remaining electron in the ionized atom is E \times Z^{2}.

Question 1
OLga [1]

Answer: 7 atm

Explanation:

According to Dalton's Law, the total pressure is the sum of all the individual gas pressures

Hence, Ptotal = P1 + P2 + P3

Since, Gas A = 2 atm

Gas B = 1 atm

Gas B = 4 atm

Ptotal = (2 + 1 + 4) atm

Ptotal= 7 atm

Thus, the total pressure of the gas mixture is 7 atmosphere.

When sulfur burns, it forms sulfur dioxide (SO2). Its chemical reaction is S + O2 → SO2.
Elenna [48]

Answer:

The mass of SO2 will be equal to the sum of the mass of S and O2.

Explanation:

This can be explained by the <em>Law of Conservation of Mass</em>. This law states that mass can neither be created nor destroyed. Knowing this, we can say that the reactants of a chemical reaction must be equal to the products.

In this case, the reactants Sulfur (S) and Oxygen (O2) must equal the mass of the product Sulfur Dioxide (SO2). Therefore, the statement <em>"The mass of SO2 will be equal to the sum of the mass of S and O2" </em>is correct.

A gas has a volume of 62.65L at O degrees Celsius and 1 atm. At what temperature in Celsius would the volume of the gas be 78.31
Anastaziya [24]

Answer:

The volume of the gas will be 78.31 L at 1.7 °C.

Explanation:

We can find the temperature of the gas by the ideal gas law equation:

PV = nRT

Where:

n: is the number of moles

V: is the volume

T: is the temperature

R: is the gas constant = 0.082 L*atm/(K*mol)

From the initial we can find the number of moles:

n = \frac{P_{1}V_{1}}{RT_{1}} = \frac{1 atm*62.65 L}{(0.082 L*atm/K*mol)*(0 + 273)K} = 2.80 moles

Now, we can find the temperature with the final conditions:

T_{2} = \frac{P_{2}V_{2}}{nR} = \frac{612.0 mmHg*\frac{1 atm}{760 mmHg}*78.31 L}{2.80 moles*0.082 L*atm/(K*mol)} = 274.7 K

The temperature in Celsius is:

T_{2} = 274.7 - 273 = 1.7 ^{\circ} C

Therefore, the volume of the gas will be 78.31 L at 1.7 °C.

I hope it helps you!
