Answer:b/ less stable

Explanation:

Many elements that have one or more isotopes which are radioactive in nature have the nucleus which remains in an unstable state. The unstable nucleus breaks down, decay and emit the radiation. The nucleus in the atoms of these elements are unstable because it consists of unstable ratio of protons to neutron.

If I have an unknown quantity of gas at a pressure of 380 mmHg, a volume of 25 L, and a temperature of
Bess [88]

Answer:

                     0.5077 moles

Explanation:

Data Given:

                Moles  =  n  =  <u>???</u>

                Temperature  =  T  =  300 K

                 Pressure  =  P  =  380 mmHg = 0.50 atm

                 Volume  =  V  =  25 L

Formula Used:

Let's assume that the hydrogen gas in balloon is acting as an Ideal gas, the according to Ideal Gas Equation,

                 P V  =  n R T

where;  R  =  Universal Gas Constant  =  0.082057 atm.L.mol⁻¹.K⁻¹

Solving Equation for n,

                 n  =  P V / RT

Putting Values,

                 n  =  (0.50 atm × 25 L) / (0.082057 atm.L.mol⁻¹.K⁻¹ × 300 K)

                 n  = 0.5077 moles
