The density of the cube in grams per cubic centimeter = D = 2 gram / cm³
Explanation:
The Volume Of the Cube is V = a³
Its is given that the cube has sides measuring 5 cm each side.
V = ( 5 )³
= 5cm 5cm 5cm
V = 125 cm³
The Density Formula, Density= Mass / Volume.
Given that this cube has a mass of 250 grams.
to calculate density
D = ρ = m / V
= 250 / 125
= 2
D = 2 gram / cm³
They just are very cute tho and cute and funny and
Options are as follow,
1) Flashes
2) Skips
3) Stretches
<span>4) Jumps
</span>
Answer:
Option-3 (stretches) is the correct answer.
Explanation:
The best analogy which suits a chemical bond is the stretching of chemical bonds. Remaining verbs doesn't explain the property of chemical bond. For example, the chemical bonds did not flashes, neither they skip or jump.
The chemical bonds can stretch and bend. As predicted from IR spectroscopy, different bonds can stretch and bend at different energies. The stretching of bonds require more energy while, bending of bonds require less energy.
Answer:
The value of Kp for the system = 0.0128 atm
Explanation:
Let, the gaseous substance is SO₂Cl₂
SO₂Cl₂ ⇄ SO₂ + Cl₂
Initially x 0 0
At equilibrium (x - 14.5%x) 14.5%x 14.5%x
= 85.5 % x
Total moles of gases at equilibrium
= 85.5 % x + 14.5%x + 14.5%x
= 114.5 % x
Partial pressure of SO₂ () =
Partial pressure of Cl₂
Partial pressure of SO₂Cl₂
So,
Since N2 is a covalent bond, the lewis dot structure of N2 would have a triple bond. Each bond contains 2 electrons, so if it has a triple bond it contains 6 electrons.
Calculate the number of valence electrons of N2
N= 2x 5 = 10
N2 has a total of 10 valence electrons, to become stable each N atom needs 8 electrons.
So, therefore, 6 electrons would have to be a part of covalent bonds because they share 6 electrons in a triple bond.
