The correct answer is A) They all have similar chemical properties.
Explanation:
In chemistry, the periodic table organizes visually the chemical elements. In this, elements are arranged according to different features. In the case of families of the elements, these refer to elements organized in the same column, for example, elements that are in column 18 form a family called noble gases.
These elements form a family because they have chemical properties; in the case of noble gases, this includes similar reactivity and physical features such as color and odor. Besides this, the elements of one family share a similar electron configuration but not the same number of electrons. This means, from the options given the one that identifies the elements that belong to a family is "They all have similar chemical properties".
Most foods that are high in calcium are poor sources of iron. this statement illustrates the characteristic of a nutritious diet known as balance.
Nutrition is the biochemical and physiological processes by which organisms use food to sustain life. It provides organisms with nutrients that can be metabolized to produce energy and chemical structures. An inadequate supply of nutrients leads to malnutrition.
Although these two definitions may seem similar, there are differences. Health simply means food that protects you from disease and keeps you alive.

<h3>
Answer:</h3>
1170.43 m³
<h3>
Explanation:</h3>
<u>We are given;</u>
- Initial pressure, P1 as 808 kPa
- Initial temperature, T1 as 585 K
- Initial volume, V1 as 295 m³
- New pressure, P2 as 102 kPa
- New temperature, T2 as 293 K
We are required to find the new volume;
- We are going to use the combined gas law
- According to the gas law;
- Thus, rearranging the formula;
Therefore, the volume is 1170.43 m³
