Answer is: <span>name of the product nuclide is thorium-230.

<span>Alpha particle is
nucleus of a helium-4 atom, which is made of
two protons and two neutrons.
²³</span>⁴U → ²³⁰Th + α (alpha
particle).
Alpha
decay is radioactive decay in which an atomic
nucleus emits an alpha particle (helium nucleus) and transforms
into an atom with an atomic number that is reduced by
two and mass number that is reduced by four.
Answer:
Ice floats on water because it is less dense than water. When water freezes into its solid form, its molecules are able to form more stable hydrogen bonds locking them into positions. Because the molecules are not moving, they're not able to form as many hydrogen bonds with other water molecules. Ice is a unique substance because it is solid-state — ice — is less dense than its liquid state. Because of this property, ice floats in water. Physical properties are characteristics of a substance. They do not change. Ice floats on water because it is less dense than water. When water freezes into its solid form, its molecules are able to form more stable hydrogen bonds locking them into positions.
Actions form positive ions while anions forms negative
Answer:
There are many benefits to being fit.
Explanation:
Fitness isn't just about the physical part but also the mental wellbeing. For example the physical involves exercising, not just to lose weight or look more beautiful (remember everyone has unique looks) but to live longer, reduce the rick of diseases such as heart diseases and to enhance our bodies. Whereas the mental has to do with the brain, how you train the brain e.g logic puzzles, riddles and so on.
14040/4=3510 wheels per 4 nuts
3510/4=877.5 cars per 4 wheels
877 possible cars.
actual yield 850/theortical yield 877=96.92%
