What are the difference between atomic number and atomic mass ?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

The relationships among which variable quantities are expressed by the ideal gas law equation?
A. pressure, volume, temperature, number of moles
B. volume, temperature, number of moles, gas constant
C. pressure, volume, number of moles, mass
D. pressure, volume, temperature, molar mass
Answers
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.

Combustion of 28.0 g of gasoline releases 322 kcal of thermal energy. How many kilojoules of energy are released?
Answers
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:
1 cal = 4.1868 J (joules)1 kcal = 1000 cal1 kJ = 1000 JHence, 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]

C. An increase in temperature lowers the reaction's activation energy.
D. An increase in temperature changes equilibrium concentrations.
SUBMIT
Answers
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.
What is Arrhenius equation?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.

Nitroglycerine, used to treat patients with angina, is prescribed for a patient by IV at a rate of 2.10 x 102 ug/min. The IV bag
contains 50. mg nitroglycerine/250 mL D5W. How many milliliters per hour should the patient receive?
Answers
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.

Convection currents in the atmosphere influence many weather patterns. What property of the air has the most influence on convection currents?
1. The direction of the wind
2. The velocity of the wind
3. The temperature of the air
4. The mass of the air
Answers
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.
What effect on the climate does convection have?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.
How do air masses respond to convection currents?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.
