(A) Climate zones at low latitudes are hotterbecause they receive more direct sunlight. This is because the Earth's surface at the equator is closer to the sun and therefore receives more direct sunlight
Additionally, the distance of a region from the equator affects its precipitation pattern, with regions closer to the equator generally receiving more precipitation than regions at higher latitudes.
As a result, the tropics, which lie near the equator, tend to be warmer than other regions. In contrast, regions at high latitudes receive less direct sunlight due to the curvature of the Earth's surface, resulting in colder temperatures.

The volume of one mole of gas at STP is 22.4 liters.
In the combustion reaction of acetylene (C2H2), 60 liters of CO2 will be produced if 60 liters of O2 is used.
To determine the volume of CO2 produced in the combustion reaction of acetylene (C2H2), we need to use stoichiometry. From the balanced equation, we can see that 2 moles of C2H2 produce 4 moles of CO2. The ratio is 2:4 or 1:2. Given that 60 liters of O2 is used, we can assume the same volume of CO2 will be produced since both gases are at STP.
Therefore, the volume of CO2 produced would be 60 liters as well.

The sulfur atom has 16 electrons. The electronic configuration of sulfur is 2, 8, 6.
Sulfur has been the bright yellow, crystalline nonmetal. It has been present in abundance in nature. The sulfur has been used in the gunpowder, as well as fungicide, and in the vulcanization of black rubber,
The electronicconfiguration has been the filling up of electrons of an element in the atomic shells.
The order for filling the shells involves the 2,8,8,14, and so on.
The sulfur has the atomic number 16. It states that it has 16 electrons in the atom.
The electronic configuration of sulfur is as follows:
2,8,6.
The sulfur atom has 16 electrons. The electronic configuration of sulfur is 2, 8, 6.

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".
Each set of elements has an equal number of electrons in the outer orbital. We refer to these as valence electrons. Each element's chemical characteristics are determined by its valence electrons. The correct option is A.
The elements in the same group or column of the periodic table are those whose chemical characteristics are the most comparable. The vertical groups of elements that have the same number of valence electrons and, consequently, comparable chemical characteristics are formed when the elements are arranged in order of atomic number.
Only when matter changes to become a completely other sort of matter can chemical characteristics be measured or observed. They consist of flammability, reactivity, and rusting potential.
Thus the correct option is A.
