Answer:
During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod. 3.
Answer:
Firstly, the name of the element is Rhodium, symbol Rh, Atomic number 45, Mass number 102.9 (103)
Answer:
If you break a bone, your body immediately begins producing new cells to heal the damage. When your skin is cut, platelets in your blood clot to stop the bleeding, white blood cells remove the dead, injured cells and new healthy cells repair the damaged tissue.
Explanation:
Answer:
1.7 atm
Explanation:
For first syringe :
Pressure = 1.2 atm
Temperature = 325 K
Volume = 589 mL = 0.589 L (1 mL = 0.001 L)
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
1.2 atm × 0.589 L = n × 0.0821 L.atm/K.mol × 325 K
⇒n = 0.02649 moles
For second syringe :
Pressure = 2.6 atm
Temperature = 298 K
Volume = 473 mL = 0.473 L (1 mL = 0.001 L)
Using ideal gas equation as:
PV=nRT
Applying the equation as:
2.6 atm × 0.473 L = n × 0.0821 L.atm/K.mol × 298 K
⇒n = 0.050266 moles
Total moles = 0.02649 moles + 0.050266 moles = 0.076756 moles
Volume = 1 L
Temperature = 0.00 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T = (0 + 273.15) K = 273.15 K
Using ideal gas equation as:
PV=nRT
Applying the equation as:
P × 1 L = 0.076756 × 0.0821 L.atm/K.mol × 273.15 K
⇒Total P = 1.7 atm
