Answer:
1.3 atm
Explanation:
Apply the ideal gas law: PV = nRT
Since we need to find the pressure, solve for pressure:
P = nRT / V
Plug in our given values of n = 4.6 moles, R = 0.08206 (ideal gas law constant using atm), T = 325 K, and V = 96.8 L:
P = 4.6(0.08206)(325) / 96.8 = 1.267 atm -> 1.3 atm (two significant figures)
Answer:
about 55 kilometers per hour
Explanation:
distance divided by time = 500/9
Answer:
Blue and Green marbles
Explanation:
We have been given that:
Number of Marbles:
Blue(Protons) = 3
Green(Neutrons) = 4
Red (Electrons) = 3
The marble that should be placed in the nucleus of a lithium atom = ?
Solution:
The nucleus of an atom is made up of protons and neutrons.
Protons are the positively charged particles in an atom.
Neutrons do not carry any charges.
So;
The marble in the nucleus are the Blue and Green marbles.
