Answer:
Nitrogen = 0.3 atm
Oxygen = 0.25 atm
Argon = 0.45 atm
Explanation:
According to Dalton's law of partial pressure, the total pressure in the container is equal to sum of the partial pressures of the individual gases.
Given;
Total pressure of the gases, P_total = 1 atm
Pressure of nitrogen, P_nitrogen = 0.3 atm
Pressure of oxygen, P_oxygen = 0.25 atm
Pressure of argon, P_argon = ?
Therefore, the contribution of each gas to the total pressure of the gas mixture is;
Nitrogen = 0.3 atm
Oxygen = 0.25 atm
Argon = 0.45 atm
The correct answer is C - sound.
Sound is a wave, and it is thus not considered a form of matter.
C it is c the answer is c it’s c
Answer:
C = 107.97 mol/L
Explanation:
Given data:
Volume of solution = 1.38 mL (1.38 mL× 1 L /1000 mL = 0.00138 L)
Mass of ammonium sulfite = 17.36 g
Concentration of solution =?
Solution:
We will calculate the number of moles of ammonium sulfite.
Number of moles = mass/molar mass
Number of moles = 17.36 g / 116.15 g/mol
Number of moles = 0.149 mol
Concentration:
C = n/V
C = concentration
n = number of moles of solute
v = volume in L
C = 0.149 mol / 0.00138 L
C = 107.97 mol/L
The resistance of the wire is dependent on temperature, diameter and nature of the material.
<h3>What is resistance?</h3>
The term resistance refers to the opposition offered to the flow of current in a circuit. The resistance is obtained form Ohm's law which states that;
V = IR
Where;
V = voltage
I = current
R = resistance
Hence, the resistance is dependent on;
- temperature
- diameter
- material
