Hello!

I believe the gas that will diffuse more readily than neon is: Helium.

I am assuming you are talking about Neon. The rate of diffusion is directly proportional to the molar mass of the gas. Since neon has a molar mass of 20.18 grams, the gas must have a lower molar mass and must be a gas at 273 Kelvin. There are several elements that fulfill this criteria: Hydrogen, Helium, Oxygen, Nitrogen, and Fluorine.

Identify the power of ten that defines each of these prefixes. Input your answers as 10 x where x is the power of ten. nano- ___

Gemiola [76]

Answer: The quantity of every prefix is written below as a power of ten.

Explanation:

In the metric system of measurement, the name of multiples and subdivision of any unit is done by combining the name of the unit with the prefixes.

For Example: deka, hecto and kilo means 10, 100 and 1000 respectively. Deci, centi and milli means one-tenth, one-hundredth, and one-thousandth respectively.

The quantity of these prefixes are written as the power of 10.

For the given prefixes:

Nano: The quantity will be $10^{-9}$

Kilo: The quantity will be $10^3$

Centi: The quantity will be $10^{-2}$

Micro: The quantity will be $10^{-6}$

Milli: The quantity will be $10^{-3}$

Mega: The quantity will be $10^6$

Hence, the quantity of every prefix is written above as a power of ten.

The factors that can determine the outcome of a "neutralization reaction" include:
__________________________________________________________
1) temperature;

2) concentration (of the solution);

3) type of acid used;

4) type of alkali used;

5) type of reaction;
(e.g. whether the reaction is "endothermic" or "exothermic");

If Marie and Calvin dissolve 50 grams of KBr in 100 grams of water at 90oC, the solution is

hram777 [196]

Answer:

The solution is 50 %wt

Explanation:

50% wt is a sort of concentration and means, that 50 g of solute (in this case, the potassium bromide) dissolved in 100 g of water.

It is the same to say, that there are 50g of KBr for every 100g of H₂O
