Answer: The mass of aluminium cylinder is 4065 kg.
Explanation:
Density is defined as the ratio of mass of the object and volume of the object.
Mathematically,
We are given:
Density of aluminium =
Volume of aluminium cylinder =
Putting values in above equation, we get:
Hence, the mass of aluminium cylinder is 4065 kg.
b. rock and mineral fragments
c. hydrocarbon gases
It's B.Rock and mineral fragments.
Sodium chloride is the strong electrolyte among the options provided. Strong electrolytes are substances that completely dissociate into ions when dissolved in water. Other examples of strong electrolytes include strong acids like hydrochloric acid and strong bases such as sodium hydroxide.
Among the options provided, sodium chloride is a strongelectrolyte. Electrolytes are substances that yield ions when dissolved in water. Specifically, strong electrolytes dissociate completely into ions when dissolved, leading to high conductive capacity, which is characteristic of strong electrolytes such as sodium chloride. Other substances like sugar, vinegar, or carbon tetrachloride, do not dissociate into ions when dissolved, making them non-electrolytes rather than strong electrolytes.
Examples of other strong electrolytes include strong acids like hydrochloric acid (HCl), which fully dissociates into hydrogen and chloride ions. Strong bases like sodium hydroxide (NaOH) are also strong electrolytes as they readily donate OH¯ when dissolved in water. On the other hand, weak acids and bases, such as the acids in tomato juice or vinegar, do not completely dissociate and are considered weak electrolytes.

B) radon
C) carbon monoxide
D) sulfuric acid
A secondary pollutant is one that is not directly emitted but rather forms when primary pollutants react in the atmosphere. Among the options provided, sulfuric acid is a secondary pollutant. Correct option is D.
In the context of environmental science, a secondary pollutant is a type of pollutant that is not directly emitted. Instead, secondary pollutants are formed when primary pollutants undergo chemical reactions in the atmosphere. Among the options provided, option D) sulfuric acid is a secondary pollutant. The others - sulfur dioxide, radon and carbon monoxide - are primary pollutants, as they're emitted in this form from a source.
#SPJ11
b) holds less dissolved oxygen than cold water
c) is beneficial to living organisms in aquatic ecosystems
d) contains more hydrogen than cold water
Hot water holds less dissolved oxygen than cold water.
Answer:
The chloride formed when iron reacts with hydrochloric acid is iron (II) chloride, also known as iron dichloride. The reaction between iron and hydrochloric acid is slower than the reaction with zinc, with much smaller hydrogen bubbles produced.
Answer:
The reaction of iron and hydrochloric acid is slow beacause When dilute Hydrochloric acid is added to iron filings, iron(II) chloride & hydrogen gas is produced. In this reaction iron displaces hydrogen from hydrochloric acid to form iron chloride & hydrogen gas this reaction is a single displacement reaction which reacts slowly.
