Suppose you are titrating a sulfuric acid solution of unknown concentration with a sodium hydroxide solution according to the eq
pogonyaev

Answer:

Explanation:

H ₂ S O ₄ + 2 N a O H ⟶ 2 H ₂ O + N a ₂ S O ₄

29.09 mL of 0.639 M N a O H is mixed with 213.8 mL of H ₂ S O ₄

Let the concentration of H ₂ S O ₄ be S₂ .

In terms of normal or equivalent solution is will be 2 N  solution

From the formula S₁ V₁ = S₂ V₂

= 29.09 x .639 = 213.8 x  S₂

S₂ = .087 N solution

In terms of molar solution it will be .087 / 2 M

= .0435 M

Which of these is an example of a physical change? sugar dissolving in warm water iron rusting in the presence of moist air wood
WARRIOR [948]
The correct option is; SUGAR DISSOLVING IN WARM WATER.
There are two types of change in chemistry; physical and chemical changes.
A physical change is a type of change in which no new substance is formed while a chemical change is a type of change in which a new substance is formed. 
Dissolving sugar in warm water is a physical change because no new substance is formed and the sugar can easily be recovered from the water by evaporating the water.
