Answer:

Inorganic compounds is typically chemical compound that lacks carbon hydrogen bonds.

Explanation:

Inorganic compounds most that contain carbon considered inorganic, that is study of inorganic compounds is known as inorganic chemistry.

Inorganic compounds does not necessarily mean that it does not occur within living thing,inorganic and organic chemistry is merely semantic.
Inorganic compounds are the four types of compounds like :- water, acids, salts and bases.
Inorganic compounds most of the although the compositions of the deep remain active area of investigation.
Inorganic compounds majority of its content deals with metal complexes of organic compound.
Inorganic compound define inorganic polymer as the skeletal structure that does not include carbon atoms.
Inorganic compounds is a substance that does not contain both carbon and hydrogen,inorganic compounds do contain hydrogen atoms.
Inorganic compounds are held together process extremely high melting and boiling points.

I need three examples of objects with high density and three with low density!!

Anuta_ua [19.1K]

Answer:

For example, a suitcase jam-packed with clothes and souvenirs has a high density, while the same suitcase containing two pairs of underwear has low density. Size-wise, both suitcases look the same, but their density depends on the relationship between their mass and volume. Mass is the amount of matter in an object.

Give the direction of the reaction, if K >> 1. Give the direction of the reaction, if K >> 1. The forward reaction i

anygoal [31]

Answer:

A. for K>>1 you can say that the reaction is nearly irreversible so the forward direction is favored. (Products formation)

B. When the temperature rises the equilibrium is going to change but to know how is going to change you have to take into account the kind of reaction. For endothermic reactions (the reverse reaction is favored) and for exothermic reactions (the forward reaction is favored)

Explanation:

A. The equilibrium constant K is defined as

$K=\frac{Products}{reagents}$

In any case

aA +Bb equilibrium Cd +dD

where K is:

$K= \frac{[C]^{c}[D]^{d}}{[A]^{a}[B]^{b}}$

[] is molar concentration.

If K>>> 1 it means that the molar concentration of products is a lot bigger that the molar concentration of reagents, so the forward reaction is favored.

B. The relation between K and temperature is given by the Van't Hoff equation

$ln(\frac{K_{1}}{K_{2}})=\frac{-delta H^{o}}{R}*(\frac{1}{T_{1}}-\frac{1}{T_{2}})$

Where: H is reaction enthalpy, R is the gas constant and T temperature.

Clearing the equation for $K_{2}$ we get:

$K_{2}=\frac{K_{1}}{e^{\frac{-deltaH^{o}}{R}*(\frac{1}{T_{1}} -\frac{1}{T_{2}})}}$

Here we can study two cases: when delta $H^{o}$ is positive (exothermic reactions) and when is negative (endothermic reactions)

For exothermic reactions when we increase the temperature the denominator in the equation would have a negative exponent so $K_{2}$ is greater that $K_{1}$ and the forward reaction is favored.

When we have an endothermic reaction we will have a positive exponent so $K_{2}$ will be less than $K_{1}$ the forward reactions is not favored.

${e^{\frac{-deltaH^{o}}{R}*(\frac{1}{T_{1}} -\frac{1}{T_{2}})}}$

A ball of mass 0.2 kg is dropped from a height of 10 m. How much mechanical energy does it have right before it hits the ground?

lana [24]

Answer:

19.6 J

Step-by-step explanation:

Before the ball is dropped, it has a <em>potential energy </em>

PE = mgh

PE = 0.2 × 10 × 9.8

PE = 19.6 J

Just before the ball hits the ground, the potential energy has been converted into kinetic (<em>mechanical</em>) energy.

KE = 19.6 J

Where do the gaseous elements tend to be located on the table

kotegsom [21]

Answer:

Group 8 or Group 0

Explanation:

Group 8 or Group 0 are generally inert gases with Helium as the first member in that group. Their complete duplet (in the case of Helium) and Octet (in the case of Neon) configuration makes them very stable and chemically un-reactive.
