The law of conservation holds true always so there the last two grams has be lost as a gas probably
Answer:
The new volume is 66.3 mL
Explanation:
Boyle's law states that pressure and volume are inversely proportional, and that P1V1=P2V2
P1 = 0.428 atm
P2=1.55 atm
V1 = 240 mL
V2 = ??
(0.428)(240)=(1.55)(V2)
102.72 = 1.55x
x = 102.72/1.55 = 66.27 mL.

Answer:Sodium ions
Explanation:
The membrane potential of most cells is negative, when sodium ions enters the cells, it can reverse the polarity and makes it positively charge.
Answer:
The number of protons in an atom define each individual element because the number of protons is the atomic number which is the defining property of an atom and never changes. The number of protons determines an atom's identity. For example, Oxygen has an atomic number of 8, so it has 8 protons, so no matter what ionic compound or molecule it's part of, every single Oxygen atom will always have 8 protons each.
