Answer:
Explanation:
The scale on a map represents the actual distance of any geographical or man made entity with respect to the map units. For example a scale of 1:10000 states that 1 unit of any mode of measurement on map is equal to 10,000 mode of measurement on ground. This mode of measurement could be cm, km , feet etc. Thus 1 cm of map may represent 1000 m, 10000 km , 200000 feet etc.
The scale is used to represent the relative distance in both horizontal and vertical directions.
The scale on a map provides a reference for understanding distances and spatial relationships of geographical features present in the map.
The scale on a map serves the purpose of representing the relationship between distances on the map and the corresponding distances in the real world.
It allows users to accurately measure distances and understand the relative sizes and proportions of features represented on the map.
The scale is typically depicted as a line or a bar, usually located in the corner of the map.
It is accompanied by numerical values indicating the units of measurement, such as kilometers, miles, or meters.
Thus, the scale on a map provides a reference for understanding distances and spatial relationships of geographical features present in the map.

Answer:
P₂ = 2.19 atm
Explanation:
Given data:
Initial volume = 1.5 L
Initial pressure =1 atm
Initial temperature = 273K
Final temperature = 26°C (26+273 = 299 K)
Final volume = 0.75 L
Final pressure = ?
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₂ = P₁V₁ T₂/ T₁ V₂
P₂ = 1 atm × 1.5 L × 299 K / 273 K × 0.75 L
P₂ = 448.5 atm .L. K / 204.75 K.L
P₂ = 2.19 atm
There are a number of ways to express concentration of a solution. This includes molarity and molality. Molarity is expressed as the number of moles of solute per volume of the solution while molality is expressed as the number of moles solute per mass of solution.
Molarity = 5.25 mol / kg solution (1.266 kg / L) = 6.65 M
Answer:
B. Lithium (Li)
Explanation:
Lithium forms an ionic compound with nitrogen with the general formula X₃N. When lithium and nitrogen react, they form a nitride called lithium nitride.
The Lithium nitride is actually prepared by the direct combination of elemental lithium with nitrogen gas. Below is the reaction equation:
6Li + N₂ → 2Li₃N
The reaction can occur when a solution of lithium in liquid sodium metal is treated with N₂. When the Lithium nitride reacts with water, it does that violently and produces ammonia.
Answer:
Atoms of the same element are identical.
The answer is a Nucleus. Eukaryotic cells have nuclei while;e prokaryotic cells do not.
