Answer:
vHe / vNe = 2.24
Explanation:
To obtain the velocity of an ideal gas you must use the formula:
v = √3RT / √M
Where R is gas constant (8.314 kgm²/s²molK); T is temperature and M is molar mass of the gas (4x10⁻³kg/mol for helium and 20,18x10⁻³ kg/mol for neon). Thus:
vHe = √3×8.314 kgm²/s²molK×T / √4x10⁻³kg/mol
vNe = √3×8.314 kgm²/s²molK×T / √20.18x10⁻³kg/mol
The ratio is:
vHe / vNe = √3×8.314 kgm²/s²molK×T / √4x10⁻³kg/mol / √3×8.314 kgm²/s²molK×T / √20.18x10⁻³kg/mol
vHe / vNe = √20.18x10⁻³kg/mol / √4x10⁻³kg/mol
<em>vHe / vNe = 2.24</em>

The land is warm during the day. For example, if you near a sea early in the morning, you could see how cold, cool the place is.
You didn't put a + charge on one of the Ag. It has to be on the left side
2H2O + MnO2 ==> MnO4^- + 3e + 4H^+
Ag^+ + e ==> Ag^+
Those are the two BALANCED half reactions. Multiply equation 1 by 1 and equation 2 by 3 and add them.
Answer:
c
Explanation:
neutrons have no charge
protons and electrons have opposite charges and balance each other out in equal numbers
The number of hydrogen atoms is twice the number of oxygen atoms in ribose.
<h3>What is Ribose?</h3>
This is a sugar and a component of the ribonucleotides from which RNA is built. It has the formula C₅H₁₀O₅.
Ribose is a carbohydrate with the formula C₅H₁₀O₅. This molecule is a pentose monosaccharide which has a linear form 
. The hydroxyl groups lie on the same side in the form of Fischer Projections.
The number of hydrogen atoms is double the number of oxygen atoms. The ribose sugar is found in the RNA.
It is the genetic material which is found in some organisms that carry information from one generation to another.
