Explanation:

No. Different acids have different strengths . The amount of dissociation to H+ concentration , for the same concentration a strong acids would have a lower pH ( H+ concentration ) and a weak acid would have a higher pH ( lower H+ concentration )

Genrish500 [490]

Propene is the unsaturated compound.

Explanation:

In the presence of sulphuric acid (H₂SO₄), propanol will eliminate one water molecule (H₂O) to form propene, which is the unsaturated compound.

The amount of heat required to raise the temperature of a sample of water is referred to as the

HACTEHA [7]

Specific heat is the amount of heat required to raise the temperature of a sample of water.
joule is the SI unit to measure the amount of heat. Specific heat is also known as Specific heat Capacity, it is the heat per unit mass to increase temperature of one degree Celsius. We can calculate the specific heat capacity by using this formula: E = mcθ

Consider the dissolution of MnS in water (Ksp = 3.0 × 10–14). MnS(s) + H2O(l) Mn2+(aq) + HS–(aq) + OH–(aq) How is the solubility

Mademuasel [1]

Answer:

The solubility of MnS will decrease on addition of KOH solution.

Explanation:

As per the equation given:

$MnS(s)+H_{2}O(l) -->Mn^{+2}(aq)+HS^{-}(aq)+OH^{-}(aq)$

On dissolution of MnS in water it gives a basic solution as it gives hydroxide ions.

Now when the we are adding aqueous KOH solution, it will dissociate as:

$KOH(aq)--->K^{+}(aq)+OH^{-}(aq)$

Thus it will further furnish more hydroxide ion,

This will increase the concentration of hydroxide ions (present of product side), the system will try to decrease its concentration by shifting towards reactant side.

Thus the solubility of MnS will decrease on addition of KOH solution.

How do I indicate if the element is ionic or covalent?

vampirchik [111]

Answer:

There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.
