Answer:
49.35 mL
Explanation:
Given: 56.2 mL of gas
To find: volume that 56.2 mL of gas at 820 mm of Hg would occupy at 720 mm of Hg
Solution:
At 820 mm of Hg, volume of gas is 56.2 mL
At 1 mm of Hg, volume of gas is ![\frac{56.2}{820}](https://tex.z-dn.net/?f=%5Cfrac%7B56.2%7D%7B820%7D)
At 720 mm of Hg, volume of gas is ![\frac{56.2}{820}(720)=49.35\,\,mL](https://tex.z-dn.net/?f=%5Cfrac%7B56.2%7D%7B820%7D%28720%29%3D49.35%5C%2C%5C%2CmL)
Answer:
study of chemical used in industries
The answer is C, Uranium.
Natural gas, coal, and oil are all naturally made from fossils. Uranium is an element which can be found on the Periodic Table of Elements.
All acids only conduct electric current when they are dissolved in water, because when they are in an aqueous medium, they undergo ionization, i.e. release <span>ions.</span><span>
HCl --> H</span>⁺ + Cl⁻
The bases also conduct electric current in solution, because the Ionic dissociation sufferers (release the existing ions in the formula) and molecular ionization, suffer the reacting with water and releasing ions.
NaOH ---> Na⁺ + OH⁻
hope this helps!
