Answer:
Certain types of atoms are "radioactive," meaning that they will eventually decay, or "break down" into a different type of atom. In this activity, you will simulate radioactive decay by flipping coins. Coins that land tails-up "decay," and coins that land heads-up remain the same.

Since the oxygen likes to hog all the electrons, it gives the hydrogen molecules a slight positive charge and the itself a slightly negative charge.
Positive attracts negative, so there is some sort of attraction between water molecules, though a weak one.
Answer:
It will exert the pressure at a temperature of <em><u>153.44 K</u></em>
Explanation:
To answer this question, we shall be using the ideal gas equation;
PV = nRT
Since we are calculating the temperature, it can be made the subject of the formula.
Thus, this can be T = PV/nR
where P is the pressure = 900 torr
V is the volume = 0.75 L
n is the number of moles = 0.0705 mol
R is the molar gas constant = 62.4 L.Torr.
.
Plugging these values into the equation, we have;
T = (900 × 0.75)/(0.0705 × 62.4)
T = 153.44 K
