(2) temperature of the solution decreases
(3) pressure on the solution increases
(4) pressure on the solution decreases
Answer: Option (1) is the correct answer.
Explanation:
Solubility of a solute gets affected by change in temperature. That is, when we increase the temperature then more and more solute particles will dissolve into the solvent or solution.
Therefore, solubility of KClO3(s) in water increases as the temperature of the solution increases because on increasing the temperature it will completely dissociate into the solution.
635 g
635 g/cm3
634.5 ml
Answer:
JUST B
Explanation:
The mass of 235 cm³ of aluminum, which has a density of 2.70 g/cm³, is calculated to be 634.5 g using the formula Mass = Density × Volume.
To find the mass of a given volume of a substance, you can use the formula: Mass = Density × Volume. In this case, the density of aluminum is given as 2.70 g/cm³ and you need to find the mass of 235 cm³ of aluminum.
Substitute the given values into the formula:
Mass = 2.70 g/cm³ × 235 cm³ = 634.5 g
Therefore, the mass of 235 cm³ of aluminum is 634.5 g.

Set of elements which has similar properties is helium,neon,argon.
Elements in the periodic table are arranged according to their atomic numbers according to modern periodic law which states that properties of elements are a periodic function of their atomic numbers.
In a group, elements have same number of valence electrons as for every element in a group a new shell is added and hence number of valence electrons remain same. In a period, electrons are added to same shell for every element present in the same period,because of which valence electrons do not remain same.
Valence electrons take part in chemical reactions and as they are same for elements present in the same group they have similar properties while for elements present in a period since they have different number of valence electrons they differ in properties.
