Ionic compounds are normally in which physical state at room temperature in solid. The answer is A.

Ionic Compounds Are Balanced. Table salt is an example of an ionic compound. Sodium and chlorineions come together to form sodium chloride, or NaCl. The sodium atom in this compound loses an electron to become Na+, while the chlorine atom gains an electron to become Cl-.

Answer: Option (a) is the correct answer.

Explanation:

Ionic compounds have atoms bonded through ionic bonds.

An ionic bond is formed when there is transfer of electrons from one atom to another. Also, ionic compounds have opposite charge on their atoms hence, they are attracted by strong intermolecular forces.

Thus, compound whose atoms are holded by strong intermolecular forces of attraction are solid.

Therefore, we can conclude that ionic compounds are normally in solid physical state at room temperature.

Why does increasing the temperature speed up a reaction?

Otrada [13]

Answer:

Explanation:

The increase of temperature makes the molecules collide more frequently which therefore means they also have more kinetic energy stored in them. This means there's more energy available for the molecules to use to overcome the activation energy.

Four gases were combined in a gas cylinder with these partial pressures: 3.5 atm N2, 2.8 atm O2, 0.25 atm Ar, and 0.15 atm He. W

Marat540 [252]

Answer :

The total pressure inside the cylinder is, 6.7 atm

The mole fraction of $N_2$ in the mixture is, 0.52

Solution :

First we have to calculate the total pressure inside the cylinder.

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.

$P_T=p_{N_2}+p_{O_2}+p_{Ar}+p_{He}$

Now put all the given values is expression, we get the total pressure inside the cylinder.

$P_T=3.5+2.8+0.25+0.15=6.7atm$

Now we have to calculate the mole fraction of $N_2$ in the mixture.

Formula used :

$p_{N_2}=X_{N_2}\times P_T$

where,

$P_T$ = total pressure = 6.7 atm

$p_{N_2}$ = partial pressure of nitrogen gas = 3.5 atm

$X_{N_2}$ = mole fraction of nitrogen gas = ?

Now put all the given values in the above formula, we get

$3.5atm=X_{N_2}\times 6.7atm$

$X_{N_2}=0.52$

Therefore, the total pressure inside the cylinder is, 6.7 atm and the mole fraction of $N_2$ in the mixture is, 0.52

Which of the following colors is/are produced when white light from sun is passed through a prism?

faust18 [17]

Answer:

Options d.

Explanation:

As white light from the sun is passed through a prism, it is separated into colors - red, violet, yellow, blue, green, orange, and indigo.

Dispersion is the process of the separation of visible light into its different component colors. The light waves are refracted as they enter the prism.

So, option d. is correct.
