B. Calcium! I hope this help.
If your bones don't have enough calcium you get osteoporosis.
Answer:
Nothing
Explanation:
Thermal energy and heat are mainly related because of the fact that the faster molecules move, the more heat is created. If molecules are vibrating slower, that means that there will be less energy, resulting in less heat. Say I am boiling water. As the temperature increases, the water molecules move faster. Once that water cools, the molecules will be moving really slowly. In conclusion, thermal energy and heat are related because of how fast or slow the molecules move, the more or less heat and energy will be produced. I hoped this helped!
Answer: Option (b) is the correct answer.
Explanation:
Chemical properties are defined as the properties which tend to chemical composition of a substance. Neutral elements with similar number of valence electrons tend to show similar chemical properties as these have same reactivity which actually affects their chemical properties.
This means that elements of the same group tend to show similar chemical properties.
For example, oxygen and sulfur atom are both group 16 elements and they have 6 valence electrons. Therefore, they show similar chemical properties.
Thus, we can conclude that a pair of O and S elements is expected to be most similar in their chemical properties.
What is true in a saturated solution is that it cannot dissolve any more solute.
A saturated solution is a chemical solution that contains the highest concentration (maximum capacity) of a solute dissolved in the solvent. When additional solute is added to a saturated solution, it will not dissolve it but it may result in a solid precipitate or left as a gas. The saturation of a solution depends on various factors such as temperatures, pressure, and the chemical makeup of substances involved. Examples of saturated solutions include; carbonated water and mixture of sugar and vinegar.
