explain why samples of gold and copper can have the same extensive properties, but not the same intensive properties

Extensive properties, as volume and mass, depend on the amount of material. So, you can have a sample of gold and a sample of copper with the same volume as long as you have different amount of each one.

On the other hand, intensive properties do not depend on the amound of material but on the chemical constitution of the material. Density is an intensive property, so gold and copper have different densities. That is why you can use intensive properties to characterize different materials.

Oxalic acid (h2c2o4) has a ka of 5. 9×10−2, while the hydrogen oxalate anion (hc2o−4) has a ka of 6. 1×10−5. Is an aqueous solut

Resultant aqueous solution of a hydrogen oxalate salt is basic in nature.

<h3>What is pH?</h3>

pH scale is used to determine the acidity, basicity or neutral nature of any solution.

Values from 0 to 6.9 shows the acidity.
7 shows the neutrality.
And 7.1 to 14 shows the basicity.

Chemical equation for the given salt in an aqueous solution will be shown as:

NaHC₂O₄ + H₂O → NaOH + H₂C₂O₄

From the equation it is clear that reaction produces-

NaOH which is a strong base and
H₂C₂O₄ oxalic acid which is a weak acid.

So that resultant solution is basic in nature.

Hence the aqueous solution of salt is basic.

The boron atom of BBr3 has

maks197457 [2]

Answer: The boron atom of $BBr_3$ has three hybrid orbitals

Explanation: Hybridization of the molecule can be calculated by:

$Hyb=\frac{1}{2}(V+H-C+A)$ .....(1)

where,

V = number of valence electrons in the central metal atom

H = number of monovalent atoms

C = cationic charge

A = anionic charge

Here, electronic configuration of B = $1s^22s^22p^1$

Number of valence electrons = 3

Number of monovalent atoms = 3

Cationic charge = 0

Anionic charge = 0

Putting these values in equation 1, we get

$Hyb=\frac{1}{2}(3+3-0+0)=3$

As the Hybridization is 3, which means that boron has 3 hybrid orbitals.
