Answer:
Explanation:- Volume percentage is the ratio of volume of solute to the volume of solution defined in terms of percentage.
Given: volume of solute = 29.4 ml
Volume of solution= 359 ml
Answer:
130
Explanation:
This is because that 3atm of N2O4 is used up for the 6atm of NO2, so 1 atm N2O4 is left. Resulting in In(1/4).
(The other are Jupiter, Saturn,and Neptune)It's atmosphere is composed primarily of hydrogen and helium with a small amount of methane and traces of water in an ammonia Uranus gets its blue green color from methane gas.
sunlight is reflected from Uranus's clould tops, which lie beneath a layer of methane gas Uranus is clouds top with lie beneath a layer of methanol gas
THE RADIUS OF THE TENTH ORBIT IN A HYDROGEN ATOM IS 52.9A°
<h3>How does an electron orbit work? </h3>
The three-dimensional area covering the nucleus of an atom is called electron orbital. Electrons sometimes fill low-energy orbitals which are closer to the nucleus before filling the higher ones. They mostly fill the orbitals as singly as they can and that filling is known as Hund’s rule. In the wave-like property, electrons don’t orbit a nucleus in the way a planet orbits the sun but however, but they exist as standing waves. The lowest energy possible an electron can take is the same as the fundamental frequency of a wave on a string.
the radius of the first orbit =0.0529nm
radius ∝ n²/z
radius of 10th orbit =(0.0529×100)nm=52.9A°

Answer:
HF ≥ H₂O because the HF bond is more polar than the OH bond.
Explanation:
Electrons in the bond will not be shared equally. Hydrogen electronegativity value is 2,1 but Fluorine is 4, so electrons in the covalent bond will be more attracted to Fluorine. The electron cloud will be more distorted towards Fluorine.
I hope this is correct, and as always, I am joyous to assist anyone at any time.
