Answer:
Explanation:
Boyle's law states that at constant temperature:
P
PV = constant
Where: P is the pressure of a given mass of gas, and V is its volume.
The bubble wrap has a confined volume of air at constant temperature. Since a gas is easily compressible, the volume of the gas in the wrap decreases with increasing pressure. This implies that there is an inverse proportion relation between the pressure on and volume of the air.
The bubble wrap pops when stepped onto or squeezed because the pressure is high and the volume can not be compressed further. Thus, the elastic limit of the seal is exceeded. This leads to an escape of the confined air.

1 mole MgS2O3=24+2*32+3*16=136g
229g MgS2O3 = 229/136=1.6838 moles
Answer:
Na^+
Explanation:
The symbol for sodium is Na. The term "sodium ion" assumes that the reader knows that sodium's single 3s electron is susceptible to theft by any nearby element that has a high electron affinity. Sodium's ionization energy is low, allowing the 3s electron to move elsewhere and leave behinf a positively charged Na^+ atom.
Answer:
The Eukaryotic cell has a nucleus
Explanation:
Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
