Answer:

a because it help in protecting disease

In the combustion of 28.0 g of gasoline, 1348.1 kilojoules of energy are released.          

To find the energy released, we need to convert the energy in kilocalories to kilojoules.

We need to remember that:

Hence, the energy in kJ is:

[tex] E = 322 \:kcal*\frac{4.1868 \:J}{1 \:cal}*\frac{1000 \:cal}{1 \:kcal}*\frac{1 \:kJ}{1000 \:J} = 1348.1 \:kJ [/tex]

Therefore, 1348.1 kilojoules of energy are released.

Explanation:

The Atomic mass will be the same for every isotope as the number of Neutrons changes, not the number of protons.

Neon has two major isotopes. Neon-20 and Neon-22. Out of every 250 neon atoms, 225 will be Neon-2(19.992 g/mol), and 25 will be Neon-22 (21.991 g/mol), then the average atomic mass of Neon20.1974

Atomic mass of an element can be defined as the total number of neutrons and protons present in the nucleus of an atom and the  atomic number is the number of protons present in  nucleus.

the average weight of an element is called as atomic mass while atomic number is total number of protons present in the central nucleus of the atom. Atomic mass is presented a symbolic representation of A where as atomic number is represented by the letter Z.

Atomic mass can not classified  which type of element where as Atomic number classify and identify the type of element, there are different types of isotopes of an element observed on the basis of their atomic mass where as isotopes only share the same atomic number.

Neon has two isotopes such as , N e 20, N e 21 and N e 22.The average atomic mass can be calculated as:

N e  Average atomic mass = [ 19.9924 (90.92 %)] + [ 20.9940 (0.257 %)] + [ 21.9914 (8.82 %)] a m u

Given the flow rate and the amount of nitroglycerine contained in the IV bag, the patient should receive 63 milliliters per hours.

Rate of prescribed dose by IV: [tex]2.10*10^2 ug/min = 210ug/min[/tex]

Available: [tex]50mg nitroglycerine = 50000ug[/tex]

Available Volume: [tex]150mL[/tex]

Hence, [tex]50000ug = 250ml[/tex]

and volume for [tex]210ug = x[/tex]

We cross multiply to find x

[tex]x = \frac{210ug * 250mL}{50000ug} \\\\x = 1.05mL[/tex]

Meaning that in a single minute, 1.05mL is been infused into the patient

Now, for an hour, ( 60 minutes ) the volume infused will be;

[tex]1min = 1.05mL[/tex]

[tex]60min = x[/tex]

We cross multiply to find x

[tex]x = \frac{1.05mL*60min}{1min}\\\\x = 63mL[/tex]

Therefore, given the flow rate and the amount of nitroglycerine contained in the IV bag, the patient should receive 63 milliliters per hours.

Answer:

b

Explanation:

The concept Arrhenius equation is used here to determine the temperature dependence of the rate of a reaction. An increase in temperature increases the rate of a reaction. The correct option is B.

The rate of a chemical reaction is affected by the factors like temperature and activation energy. The influence of these factors on the rate of the reaction is explained by the Arrhenius equation.

The equation is given as:

[tex]k = A. e^{-} ^{E_{a} } /RT[/tex]

k - Rate constant

A - Frequency factor

Eₐ - Activation energy

R - Gas constant

T - Temperature

Since 'Temperature' appears in the denominator of the negative power of the exponential factor of the equation, it is evident that an increase in temperature increases the value of rate constant and thereby increases the rate of the reaction.

Thus the correct option is B.

movement of water from high potential to low potential

Convection currents are largely influenced by air temperature. A low-pressure area is produced when air is heated because it becomes less dense and rises.

For instance, the air above the Earth heats and rises as its surface warms from the sun. This air may continue to rise while cooling and producing cumulus clouds if the conditions allow.

Climate-affecting wind patterns are driven by convection currents. Convection currents are used to shift air masses. There are two different kinds of air masses: warm and cold. From higher latitudes to lower latitudes, cold air masses travel.

The Earth can be divided into one of two ways – mechanically or chemically. Mechanically – or rheological, meaning the study of liquid states – it can be divided into the lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core.

Explanation:

Answer:

A. Pressure, volume, temperature, number of moles

The relationships among pressure, volume, temperature, and the number of moles are expressed by the ideal gas law equation. Therefore, option A is the correct answer.

The ideal gas law equation is PV = nRT, where P represents the pressure of the gas, V represents its volume, n represents the number of moles of gas present, T represents its temperature, and R is the ideal gas constant. This equation describes the behavior of an ideal gas at standard temperature and pressure (STP).

By manipulating the ideal gas law equation, we can calculate various properties of gases, including their density, molar mass, and molecular weight. This equation is widely used in chemical engineering, thermodynamics, and other fields that deal with gases.

Thus, option A is correct.

The heat produced by hydrolysis of 65 kg of ATP is -6.8 kJ.

Let's consider the thermochemical equation for the hydrolysis of ATP.

ATP + H₂O ⇒ ADP + Pi   ΔG = -57 kJ/mol

We will convert 65 kg of ATP to moles using its molecular weight (507.18 g/mol).

[tex]65 \times 10^{3} g \times \frac{1mol}{507.18g} = 1.2 \times 10^{2} mol[/tex]

57 kJ of heat are released by the hydrolysis of 1 mole of ATP. The heat released by the hydrolysis of 1.2 × 10² moles of ATP is:

[tex]1.2 \times 10^{2} mol \times \frac{(-57kJ)}{1mol} = -6.8 \times 10^{3} J = -6.8 kJ[/tex]

-6.8 kJ is the heat produced by hydrolysis of 65 kg of ATP.
