Answer: Density, Hardness, Boiling point, Melting Point

Explanation: Physical Properties are those properties which can be measured. These are those observables which can be used to defined to the state of the system and which do not bring any change in the molecular composition of the system.

Whereas Chemical Properties are those which can bring changes in the original identity of the composition.

Out of the given, Density, Hardness, Boiling Point and Melting Point r the properties due to which the physical state of any system can be defined.

Reactivity and Flammability cannot be considered among them.

The answer to the given problem are:
1. Density
2. Hardness
3. Boiling Point 
4. Melting Point


These are the list of physical properties except for two which are reactivity and flammability. These two should be excluded in the list of physical properties.

The sp of pbbr2 is 6. 60×10−6. what is the molar solubility of pbbr2 in pure water?
Inessa05 [86]

Ksp of PbBr₂ is 6.60 × 10⁻⁶. The molar solubility of PbBr₂ in pure water is 0.0118M.

Ksp or Solubility Product Constant is an equilibrium constant for the dissociation in an aqueous solution.

Molar solubility (S) is the concentration of the dissolved substance in a solution that is saturated.

Let the molar solubility be S upon dissociation.

PbBr₂ or Lead Bromide dissociates in pure water as follows:

                          PbBr₂ ----------> Pb⁺² + Br⁻

                                                     S      2S

Ksp = [Pb⁺²] [ Br⁻]

Ksp = (S) (2S)²

Ksp = 4S³

6.60 × 10⁻⁶ = 4S³

S = 0.0118M

Hence, the Molar solubility S is 0.0118M.

Two types of heterogeneous mixtures are suspensions and colloids.<br>true or false<br><br>​
scoray [572]
<h2>Answer:True</h2>

Explanation:

Heterogeneous mixture is a mixture with non-uniform composition.

The properties of the mixture like concentration may change for different parts of the mixture.

Colloids contain solute particles of size 2nm-500nm.The presence of these particles makes the mixture heterogeneous.

Suspensions contain solute particles of size 500nm-1000nm.These particles settle to the bottom of the mixture which makes the composition of the bottom different from the top.

So,colloids and suspensions are two types of heterogeneous mixtures.

B. Calculate how many atoms of hydrogen are in 1. 75 moles of glucose (c6h12o6).
ycow [4]

Answer:

1.26x10^25 atoms of hydrogen

Explanation:

because there are 12 atoms of hydrogen in a molecule of glucose, multiply 12 by Avogadro's number (6.02x10^23) to get how many molecules of hydrogen there are in a mole of glucose. Then multiply that number by 1.75, which is the number of moles of glucose there is in this problem.
