3.5 moles of a gas will occupy 2.7 L at 1.5 atm at a temperature of 14.1K
IDEAL GAS LAW:
- The temperature of a gas can be calculated using the ideal gas law equation:
PV = nRT
Where;
- P = pressure (atm)
- V = volume (L)
- n = number of moles (mol)
- R = gas law constant (0.0821 Latm/molK)
- T = temperature (K)
- According to this question, P = 1.5atm, V = 2.7L, n = 3.5moles, T = ?
- 1.5 × 2.7 = 3.5 × 0.0821 × T
- Therefore, 3.5 moles of a gas will occupy 2.7 L at 1.5 atm at a temperature of 14.1K

Answer:
number of protons: 94
number of neutrons: 145
239
Pu
94
Explanation:
1) The atomic number, Z, of plutonium is Z = 94, i.e plutonium 94 protons
2) Plutoniun-239 is the isotope with mass number 239.
3) Mass number = number of protons + number of neutrons =>
number of neutrons = mass number - number of protons = 239 - 94 = 145
4) The notation requires that you indicate the symbol of the element with the atomic number (number of protons) and the mass number.
You put the mass number as a superscript at the left side of the symbol and the atomic number as subscript to the left of the symbol.
So, in this case the symbol is Pu, the superscript to the left is 239 and the subscript to the left is 94.

Answer:According to the sliding filament theory, a muscle fiber contracts when myosin filaments pull actin filaments closer together and thus shorten sarcomeres within a fiber.

Answer:
pH= 12.7
Explanation:
a)Keep an emergency kit and fresh water in your car in the event of _an unexpected event.
b) pOH= -log[OH-]
pOH= -log[5.00×10^-2]
pOH= 1.3
But pH+pOH= 14
pH= 14-pOH= 14-1.3
pH= 12.7
