Neptunium's only naturally occurring isotope, 23793np, decays by emitting one alpha particle, one beta particle, and one gamma r
1 answer:
The given isotope of Neptunium is
Alpha decay of an isotope results in daughter nuclide with mass number less by 4 units and atomic number less by 2 units than the parent isotope.
Alpha decay of Neptunium-237 can be represented as:
Beta decay of the above formed protactinium nuclide can be represented as:
Gamma decay releases only energy in the form of gamma rays, the nuclide remains the same.
γ
The new atom formed after the given decays is

Answer:
The volume that the sample of oxygen would occupy at 25 ° C if the pressure were reduced to 760.0 torr is 40.2 L
Explanation:
Boyle's law establishes the relationship between the pressure and the volume of a gas when the temperature is constant, so that the pressure of a gas in a closed container is inversely proportional to the volume of the container. That is, if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.
Boyle's law is expressed mathematically as:
Pressure * Volume = constant
or P * V = k
Considering an initial state 1 and a final state 2, it is true:
P1* V1= P2*V2
In this case:
- P1= 20.1 L
- V1= 1520 torr
- P2= 760 torr
- V2= ?
Replacing:
20.1 L* 1520 torr= 760 torr* V2
Solving:
V2= 40.2 L

Answer:
<h2>The answer is 4 m/s²</h2>Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
where
a is the acceleration
f is the force
m is the mass
From the question
f = 20 N
m = 5 kg
We have
We have the final answer as
<h3>4 m/s²</h3>Hope this helps you
