Answer:

²³⁵₉₂U

Explanation:

               ²³⁵₉₂U

The nuclear symbol of U- 235 should be written as;

   

235 is the mass number of uranium. The mass number is written as the superscript before the symbol of the element.

92 is the atomic number of uranium. It is written as the subscript before the symbol of the element.

1st Define Covalent bond and it's type
irakobra [83]

Answer:

  1. COVELENT BOND:-The chemical bond formed by the sharing of an electron pair between two atoms so that both the atoms get their octet complete is called covalent bond
  • SINGLE COVELENT BOND:-it is formed by sharing of one pair of electron between two atoms
  • DOUBLE COVELENT BOND:-it is formed by sharing of two pair of electron between two atoms
  • TRIPLE COVELENT BOND:- it us formed by sharing of three pair of electron beyween two atoms

2)Electron dot structures of carbon dioxide:-Oxygen atom contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond. Carbon atom contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.

3))Sulfur has an atomic number is 16 with the

symbol as 'S'

  • The electronic configuration of sulfur is said to be 2,8,6
  • The valence electrons present in sulfur is 6.
  • Sulfur forms an octet structure by connecting 8 sulfur atoms with each other by the formation of single covalent bonds.
  • The sulfur molecule's chemical formula is S8.
  • Sulfur is usually used in the manufacture of sulphuric acid.

Amateur radio operators in the United States can transmit on several bands. One of those bands consists of radio waves with a wa
NeTakaya

Answer:

7.5 × 10¹⁵ Hz

Explanation:

Given data

  • Wavelength of the radio waves (λ): 40 nm = 40 × 10⁻⁹ m = 4.0 × 10⁻⁸ m
  • Frequency of the radio waves (ν): ?
  • Speed of light (c): 3.00 × 10⁸ m/s

We can determine the frequency of the radio waves using the following expression.

c = λ × ν

ν = c/λ

ν = (3.00 × 10⁸ m/s)/4.0 × 10⁻⁸ m

ν = 7.5 × 10¹⁵ s⁻¹ = 7.5 × 10¹⁵ Hz

A rigid 3.80 L sealed vessel contains 0.650 mol Ne, 0.321 mol Kr, and 0.190 mol Xe. Find the density of the mixture in g/L.
Eddi Din [679]

Answer:

17.09g/L

Explanation:

Density = total mass of elements/ volume

We need to find the mass of each mixture constituents using their molar mass:

mole = mass/molar mass

For Neon (Ne) which contains 0.650mol;

0.650 = mass/20.18

mass = 0.650 × 20.18

mass = 13.12g

For Krypton (Kr) which contains 0.321mol;

0.321 = mass/83.79

mass = 0.321 × 83.79

mass = 26.89g

For Xenon (Xe) which contains 0.190mol;

0.190 = mass/131.3

mass = 0.190 × 131.3

mass = 24.95g

Total mass = 13.12g + 26.89g + 24.95g = 64.96g

Density = total mass / volume

Density = 64.96g / 3.80L

Density of the mixture = 17.09g/L
