A compound of formula XCl3 reacts with aqueous AgNO3 to yield solid AgCl according to the following equation: XCl3(aq)+3AgNO3(aq
Levart [38]

Answer:

Aluminum

Explanation:

Moles =\frac {Given\ mass}{Molar\ mass}

Mass of AgCl = 1.68 g

Molar mass of AgCl = 143.32 g/mol

Thus,

Moles\ of\ AgCl=\frac {1.68}{169.87}=0.01172

From the reaction below:

XCl_3_{(aq)}+3AgNO_3_{(aq)}\rightarrow X(NO_3)_3_{(aq)}+3AgCl_{(s)}

3 moles of AgCl are produced when 1 mole of XCl_3 undergoes reaction.

So,

1 mole of AgCl are produced when \frac {1}{3} mole of XCl_3 undergoes reaction.

0.01172 mole of AgCl are produced when \frac {1}{3}\times 0.01172 mole of XCl_3 undergoes reaction.

Thus, moles of XCl_3 = 0.0039 moles

Let the atomic mass of X = x g/mol

atomic mass of chlorine = 35.5 g/mol

Thus, Molar mass of XCl_3 = x + 3(35.5) g/mol = x + 106.5 g/mol

Moles = 0.0039 moles

Mass = 0.521 g

Thus, molar mass = Given mass/ Moles = 0.521 / 0.0039 = 133.5897 g/mol

So,

x + 106.5 = 133.5897

x = 27.0897 g/mol

This Atomic weight corresponds to Aluminum. Hence, X is aluminum.

X-rays with a wavelength of 8.82 nm. Calculate the frequency of the x rays
krok68 [10]

Answer:

The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.

Explanation:

Given data:

Wavelength of x-ray = 8.82 nm

frequency of x-ray = ?

Solution:

speed = Wavelength × frequency

frequency = speed /  Wavelength

c = 3 × 10⁸ m/s

f = c/ λ

f = 3 × 10⁸ m/s /8.82 × 10⁻⁹m

f = 0.340 × 10¹⁷ s⁻¹

The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.

How does Ionic Polarization works?
ziro4ka [17]

Answer:

Ionic polarization. As the name suggests, ionic polarization occurs in ionic materials. It occurs when an electric field is applied to an ionic material then cations and anions get displaced in opposite directions giving rise to a net dipole moment
