Alpha particles are helium nucleus ! so answer is A !
it is made by ionization of helium, when both the electrons are out , then two unit of positive charge is one helium and thus called alpha particle !
Answer:
Unless you mistyped the question, the answer should be 25+
I think the copper could melt to cup and the water would smell like rust
Answer:
2p
Explanation:
To solve this question, we can use Boyle's Law, which states that:
"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"
Mathematically:

where
p is the pressure of the gas
V is its volume
The equation can be rewritten as

where in this problem we have:
is the initial pressure of the Xe(g) gas
is the initial volume of the Xe(g) gas
is the final volume of the Xe(g) gas
Solving for p2, we find the final pressure of the gas:

So, the final pressure is twice the initial pressure.
