Answer:
0.0177 L of nitrogen will be produced
Explanation:
The decomposition reaction of sodium azide will be:
As per the balanced equation two moles of sodium azide will give three moles of nitrogen gas
The molecular weight of sodium azide = 65 g/mol
The mass of sodium azide used = 100 g
The moles of sodium azide used = 
so 1.54 moles of sodium azide will give = 
mol
the volume will be calculated using ideal gas equation
PV=nRT
Where
P = Pressure = 1.00 atm
V = ?
n = moles = 2.31 mol
R = 0.0821 L atm / mol K
T = 25 °C = 298.15 K
Volume = 
Explanation:
the physical and chemical properties of an element are periodic functions of their atomic number.
Answer:
Option-B (k) is the correct answer.
Explanation:
As we know the rate of reaction is given as;
Rate = k [A]ˣ
Where;
Rate = Rate of Reaction
k = rate constant
[ ] = concentration of A
x = order of reaction
So, from this equation we found that rate of reaction depends upon concentration and rate constant (k).
Now,
The rate constant is as follow,,
k = Ae^(Ea/RT)
This equation is known as Arrhenius Equation, according to this equation rate constant depends upon Temperature and Activation energy. Greater the temperature greater is the rate constant and hence greater is the rate of reaction. Or smaller the activation energy greater is the rate constant and vice versa.

Answer:</h3>
Homogeneous mixture with components of different boiling points
<h3>
Explanation:</h3>
- Distillation is a method of separating miscible mixtures which contain components that have different boiling points.
- The mixture is heated and the component with the low boiling point evaporates first. It is then condensed in the condenser and the distillate collected using a clean beaker.
- For example, a miscible solution of ethanol and water can be separated using distillation.
- Ethanol and water have different boiling points of 78°C and 100°C respectively. Ethanol is distilled out first because it has a low boiling point compared to water.
