Answer:
Temperature decreases and density increases
Explanation:
Let us remember that density of a material increases as the temperature of the material decreases. So the cooler a material becomes, the denser it becomes also.
Between points B and C, the material rapidly cools down and the temperature decreases accordingly. This ultimately results in an increase in density since cooler materials are denser than hot materials.
N just use a electronegativity table
These are called subscript number.
That is the number below the normal line of test are called subscript number.
This number indicate the indicate the number of atoms of the element present in the chemical formula.
In both of these C₆H₁₂O₆ and H₂O, the number written below the line of the text are called subscript numbers.
Answer:
3) 2KOH + H2SO4 → K2SO4 + 2H2O
Explanation:
The balanced chemical equation for the reaction of KOH and H2SO4 is,
→ 2KOH + H2SO4 → K2SO4 + 2H2O
Hence, option (3) is the correct answer.
