Because it a neutral atom, try taking aluminum foil and putting on a hot stove, it will heat up as fast as itcools down.
Answer: (1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
(2) Rates of chemical reactions are influenced by temperature and catalysts. Rates of nuclear reactions are unaffected by such factors.
(3) Nuclear reactions are independent of the chemical form of the element.

Answer:</h3>
Partial pressure of He(P(He) = 1.5 atm.
Partial pressure of Ne(P(Ne) = 1 atm.
Partial pressure of Ar(P(Ar) = 0.5 atm.
<h3>
Explanation:</h3>
According to Dalton law of partial pressure the sum of partial pressures of individual gases in a gaseous mixture is equivalent to the total pressure.
The partial pressure of a gas in a gaseous mixture is given by the product of the mole fraction and the total pressure.
Our gaseous mixture contains He, Ne, and Ar and the total pressure is 3 atm.
Since we are given the ratios of the gases in the mixture, we can calculate the partial pressure of each gas.
P(He) = 3/6 × 3 atm.
= 1.5 atm.
P(Ne) = 2/6 × 3 atm.
= 1 atm
P(Ar) = 1/6 × 3 atm.
= 0.5 atm
Therefore, the partial pressures of gases He, Ne and Ar are 1.5 atm, 1 atm, and 0.5 atm respectively.
Answer:
The pressure inside the container is 11 atm
Explanation:
We use the formula;
PV=nRT ---> P= nRT/V
P= 28 mol x 0,082 l atm/K mol x 215 K/45 L
<em>P=10,96977778 atm</em>
