The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.
The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.

Answer:
Science can not solve all of our problems. While scientific understanding can help battle things like disease, hunger, and poverty when applied properly, it does not do so completely and automatically. Furthermore, there are many areas of life where science can have little impact.
UV light could change the DNA of the skin cells of the organism, possibly causing cancer cells to form.
Answer:
A) Sedimentary
B) Weathering
Explanation:
A sedimentary soil/rock is formed when carrying agents such as wind or water carries rock pieces or soils particles from faraway places and deposit them at one place through a process known as lithification. However, increased pressure and temperature causes weathering of rocks. Changing temperature causes a rock to expand or cool alternatively thereby giving rise of internal stresses. While exfoliation is caused on increasing pressure.
