Answer: C a substance that can dissolve other substances
Explanation: A solvent is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. The quantity of solute that can dissolve in a specific volume of solvent varies with temperature
Hope this helped

15.0 g/342.2965= .0438 mol
2, because they are all a form of water.. but just in different states of matter depending on their form
An element is all the same thing. Pure, if you will.
The first one is definitely an element. The second would be a compound (it's atoms are different colors). I would say the last one is an element, since it has ll the same color of atoms.
I hope this helped you! If you have anymore questions, feel free to ask me.
Heavy elements such as radium, uranium, and thorium, all have alpha decaying nuclei. An Rn (radon) nuclei are created when a Ra (radium) nucleus decays, emitting an alpha particle in the process.
Discussion about radiation:
The radioactive process known as alpha decay, sometimes known as α radiation, involves the ejection of an alpha particle from the nucleus, which includes 2 neutrons and 2 protons.
- A helium atom's nucleus and an alpha particle have many similarities. Instability is seen as being present in all nuclei with an atomic number (Z) more than 82. These are frequently subject to alpha decay and are thought to be "neutron-rich." Heavy elements such as radium, uranium, thorium, etc., all have alpha decaying nuclei. An Rn (radon) nucleus is created when a Ra (radium) nucleus decays, emitting an alpha particle in the process.
- The mass number (A) and atomic number (Z) are typically lowered by two and four, respectively, during alpha decay. For instance, Ra-226 with atomic numbers 88 and 226 is converted into Rn-222 with the mass number 222 and atomic number 86 by alpha decay.
