Answer:
- Absolute pressure inside the ball:
. - Number of moles of air particles inside the ball, by the ideal gas law: approximately
.
Explanation:
The gauge pressure inside the ball gives the absolute pressure inside the ball, relative to the atmospheric pressure outside the ball. In other words:
.
Rearrange to obtain:
.
Look up the ideal gas constant. This constant comes in a large number of unit combinations. Look for the one that takes
for pressure and
for volume.
.
Convert the temperature to absolute temperature:
.
Assume that the gas inside this ball acts like an ideal gas. Apply the ideal gas law
(after rearranging) to find the number of moles of gas particles in this ball:
.
(Rounded to two significant figures, as in the pressure gauge reading.)
the empirical formula for a compound is Mo2Br5Cl3.
The empirical components of a compound are the best entire quantity ratio of atoms of every detail within the compound. it's miles decided using statistics from experiments and therefore empirical. as an example, the molecular formula of glucose is C 6H 12O 6 however the empirical formulation is CH 2O.
An Empirical formula is the chemical components of a compound that offers the proportions (ratios) of the elements present in the compound however no longer the real numbers or arrangement of atoms. This will be the lowest complete range ratio of the elements within the compound.
The empirical method of a compound gives the only ratio of the range of various atoms gift, while the molecular formula gives the actual range of each distinctive atom found in a molecule. If the components is simplified then it is an empirical components.

Answer:
Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic
