. If this same atom with 22 protons and 19 electrons were to gain 3 electrons, the net charge on the atom would be

frez [133]

Answer: No charge (0)

Explanation:

The atom has a proton of 22 and electron number of 19. This means the element has lost 3 electrons. Therefore, the net charge is +3.

So, if this atom gains 3 more electrons, the net charge would be zero (neutral).

The total number of electron would now be 22 which is the same as the proton number.

This implies the atom is now in an unreacted state or ground state.

When the electron cloud of a molecule is easily distorted, the molecule has a high _____________.a. polarity b. polarizability c

katovenus [111]

Answer: Option (b) is the correct answer.

Explanation:

Polarity is defined as the development of partial charges on the atoms of a molecule.

Whereas polarizability is defined as the ability or measure of how readily an electron cloud is able to get distorted. More is the polarizability more will be the electron is distorted in nature.

A dipole moment is defined as the measurement of the separation of two opposite electrical charges.

Thus, we can conclude that when the electron cloud of a molecule is easily distorted, the molecule has a high polarizability.

When coal is burned, the sulfur present in coal is converted to sulfur dioxide (SO2), which is responsible for the acid rain phe

solmaris [256]

Answer : The volume of $SO_2$ gas is, $2.75\times 10^6mL$

Explanation : Given,

Mass of S = 4.10 kg = 4100 g (1 kg = 1000 g)

Molar mass of S = 32 g/mol

First we have to calculate the moles of S.

$\text{Moles of }S=\frac{\text{Given mass }S}{\text{Molar mass }S}=\frac{4100g}{32g/mol}=128.125mol$

Now we have to calculate the moles of $SO_2$

The balanced chemical reaction is:

$S(s)+O_2(g)\rightarrow SO_2(g)$

From the balanced reaction, we conclude that

As, 1 mole of $S$ react to give 1 mole of $SO_2$

So, 128.125 mole of $S$ react to give 128.125 mole of $SO_2$

Now we have to calculate the volume of $SO_2$ by using ideal gas equation.

$PV=nRT$

where,

P = Pressure of $SO_2$ gas = 1.16 atm

V = Volume of $SO_2$ gas = ?

n = number of moles $SO_2$ = 128.125 mole

R = Gas constant = $0.0821L.atm/mol.K$

T = Temperature of $SO_2$ gas = $30^oC=273+30=303K$

Putting values in above equation, we get:

$1.16atm\times V=128.125mole\times (0.0821L.atm/mol.K)\times 303K$

$V=2747.65L=2.75\times 10^6mL$ (1 L = 1000 mL)

Therefore, the volume of $SO_2$ gas is, $2.75\times 10^6mL$
