Give an example. Because temperature is an average of the kinetic energy of the molecules, it does not depend on the amount of the substance. ... So if one object has few molecules with a high temperature, it may have the same thermal energy as another object that has many molecules at a lower temperature.

I need help...

Aneli [31]

Answer:

1. Density of the rectangular prism is 20 g/cm3

2. A material's ability to dissolve : Soubility

3. Intensive property : A physical property that is independent of sample size.

Explanation:

Volume of Prism is calculated by :

$volume = L\times W\times H$

Length = 3 cm

Width = 2 cm

Height = 1 cm

$volume = 3\times 2\times 1$

V = 6 cm3

mass = 120 g

$Density = \frac{mass}{Volume}$

$Density = \frac{120}{6}$

Density = 20 g/cm3

Solubility :

It is the chemical property of the substance.

It shows the ability of the solute to dissolve in the solvent at a given temperature.

Intensive Properties:

These are bulk properties(Do not depend upon the amount of matter present)
They are independent of sample size.
Example : boiling point,melting point,temperature,refractive index

The reaction of nitrogen gas and oxygen gas to form nitrogen monoxide gas is shown below. If the measured concentrations of all

Anettt [7]

Answer:

The forward reaction is occurring at a faster rate than the reverse reaction.

Explanation:

Reaction quotient (Q) of the given reaction is -

$Q=\frac{[NO]^{2}}{[N_{2}][O_{2}]}$

where [NO], $[N_{2}]$ and $[O_{2}]$ represents concentrations of respective species at a certain time.

Here $[N_{2}]$ = 0.80 M, $[O_{2}]$ = 0.050 M and [NO] = 0.10 M

So, $Q=\frac{(0.10)^{2}}{(0.80)\times (0.050)}=2$

Hence $Q> K$

It means that forward reaction is faster than reverse reaction at that point. Because then only concentration of NO is higher than concentrations of $[N_{2}]$ and $[O_{2}]$ which makes Q higher than K.

Which statement is true about BF3, a nonpolar molecule? It has nonpolar bonds and a symmetrical structure. It has nonpolar bonds

konstantin123 [22]

I think the correct answer is the first option. It has nonpolar bonds and a symmetrical structure. The structure of a BF3 molecule shows a symmetrical trigonal geometry. The net dipole moment of the molecule is zero therefore it is polar.

what is the Thermodynamics of leaching of ilmenite in hydrochloric acid for titania pigment production?

postnew [5]

The thermodynamics of leaching of ilmenite in hydrochloric acid for titania pigment production is an industrial production of nano-sized titanium dioxide (TiO2).

<h3>What is thermodynamics?</h3>

Thermodynamics is defined as the change in the energy of system that brings about work in that system.

The leaching of ilmenite which is a titanium-iron oxide mineral with HCl can lead to the production of titanium dioxide (TiO2).

The use of thermodynamics in this process controls the heat and energy of the leaching system leading to a better yield of final products.
