Answer is: B) O2 is a molecule.

Pure substance is made of only one type of atom (element) or only one type of molecule (compound).

For example, hydrogen peroxide (H₂O₂), sodium chloride (NaCl) are compounds, lithium (Li) is an element and oxygen (O₂) is a molecule.

Molecules can be homonuclear (molecule made of two atoms of the same element, in this example oxygen) and heteronuclear (molecule made of two different atoms, for example water).

The period 4 alkaline-earth metal has the name_______ . An isotope of this element having 20 neutrons has amass numberof _______
Cerrena [4.2K]

Answer:

The period 4 alkaline-earth metal has the name Calcium. An isotope of this element having 20 neutrons has a mass number of 40.

Explanation:

Looking at the periodic table 4th row for the alkaline-earth metal, we can find Calcium which has an atomic number of 20 (or protons number, or z). The mass number is given by the sum of protons and neutrons. If the number of protons in this case is 20 and the number of neutrons is also 20, the mass number A = 40.

Does the temperature of the solvent (water) affect the rate of dissolving?​
gregori [183]
Yes. Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.
