Answer:
need more info
Explanation:
i think so we need more info
Explanation:
In solids, the particles are tightly packed together. In liquids, the particles have more movement, while in gases, they are spread out. Particles in chemistry can be atoms, ions or molecules. It is important to understand the particle nature of matter.
Answer:
<h2>5.49</h2>
Explanation:
The pH of a solution can be found by using the formula
![pH = - log ([ { H_3O}^{+}])](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%28%5B%20%7B%20H_3O%7D%5E%7B%2B%7D%5D%29)
H3O+ is the hydronium ion
From the question we have
We have the final answer as
<h3>5.49 </h3>
Hope this helps you
A)CH3OCH3 is the isomer of CH3CH2OH
Answer:
0.1935atm is the pressure of the gas.
Explanation:
In the problem you have the mass of Neon (You can obtain moles using molar mass), you have volume, and temperature. You can use general ideal gas law to solve pressure:
PV = nRT
P = nRT / V
<em>Where P is pressure in atm, n are moles, R is gas constant (0.082atmL/molK), T is absolute temperature (20.0°C + 273.15 = 293.15K), and V is volume in L = Volume in dm³</em>
<em />
<em>Moles gas:</em>
Molar mass Ne = 20.1797g/mol
0.325g * (1mol / 20.1797g) = 0.0161 moles
Replacing:
P = nRT / V
P = 0.0161 moles * 0.082atmL/molK * 293.15K / 2L
P = 0.1935atm is the pressure of the gas
