Identify the particle represented by each symbol as an alpha particle, a beta particle, a gamma ray, a positron, a neutron, or a proton. a. 11P
b. 42He
c. +10e

is symbol for proton emission in the nucleus.

symbolises alpha emission, equivalent to helium atom emission of a radioactive particle

is the radiation symbol for positiron particle. which occurs when beta + radioactive decay occurs

introduction of a drug directly into the respiratory tract is a form of inhalation administration.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
