political map
population map
relief map
The correct answer is (b) political map
The explanation:
when a political map: is different than other types of maps because it focuses on government or administrative boundaries rather than geographical or physical features. Instead of showing viewers what exists in the land, it shows those imaginary lines that serve to separate countries, states, territories, and cities. These maps generally include larger bodies of water, such as oceans, rivers, and lakes, as landmarks.
It was made by man not natural like the others maps.
so this is the correct answer.
A political map is the best tool to locate the boundaries between countries, providing distinct and accurate depiction of governmental boundaries.
The best tool to use to locate the boundaries between countries is a political map. Political maps are designed to show governmental boundaries of countries, states, and counties.
They also indicate the location of major cities, and they usually include significant bodies of water.
Unlike other types of maps like interrupted area maps, population maps, or relief maps, a political map focuses specifically on the delineation of imaginary lines separating different political entities, making it the ideal tool for identifying country boundaries.

Answer: A - Structural models provide minimal three-dimensional information.
Explanation:
To find the number of moles in 30 grams of H3PO4, divide the mass by the molar mass. In this case, there are 0.306 moles of H3PO4.
To determine the number of moles in 30 grams of H3PO4, we need to use the molar mass of H3PO4. The molar mass of H3PO4 is 98.0 g/mol.
We can use the following conversion factor to convert grams to moles: 1 mole = molar mass (in grams).
Therefore, the number of moles in 30 grams of H3PO4 is calculated as:
30 grams x (1 mole / 98.0 grams) = 0.306 moles of H3PO4.

The correct statements are -
Oxidation state, also known as oxidation number, is a measure of the degree of oxidation or reduction of an atom within a compound or ion. It indicates the number of electrons that an atom has gained or lost, or the hypothetical charge that it would have if all the shared electrons in a compound were assigned to the more electronegative atom.
The oxidation state of an atom can be positive, negative, or zero. In a neutral molecule, the sum of the oxidation states of all the atoms must be zero. In ions or compounds, the sum of the oxidation states of all the atoms must be equal to the overall charge of the species.
Oxidation states are assigned based on a set of rules that consider the electronegativity of atoms, the number of valence electrons, and the distribution of electrons in a molecule or ion. The oxidation state provides information about the reactivity, bonding, and redox reactions of substances. It is often represented by Roman numerals or as a signed integer.
