Answer:
DUDE ITS THE THIRD ANSWER FROM THE TOP
....... HOPE THIS HELPS ✌
B because isotopes have the same number of protons but a different number of neutrons
Answer:
The pressure of the gas after getting compressed is 1.92 L.
Explanation:
To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
(At constant temperature)
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
The pressure of the gas after getting compressed is 1.92 L.
Answer:
106.905 amu is the mass of the other isotope
Explanation:
The atomic mass of an element is the sum of the masses of the isotopes multiplied by its abundance. The atomic mass of an element X with 2 isotopes is:
X = X-109*i + X-107*i
Where X is the atomic mass = 107.868 amu
X-109 = 108.905amu, i = 48.16% = 0.4816
X-107 = ?, i = 1-0.4816 = 0.5184
Replacing:
107.868amu = 108.905amu*0.4816 + X-107*0.5184
55.4194 = X-107*0.5184
106.905 = X-107
<h3>106.905 amu is the mass of the other isotope</h3>
Answer:
The voltage or potential difference
Explanation:
What makes current flow in a circuit is the voltage or the potential difference.
This force is supplied by the battery or the mains electrical circuit.
- Every circuit requires the voltage to drive current through
- When a circuit is complete, the battery is able to overcome any resistance by the generating enough voltage which is the force to drive the current through.
