1) Acidic solution. An acidic solution has a high concentration of H+ ions.
2) Basic solution. A basic solution has a high concentration of OH- ions.
3) HCl chemical reaction.
You can also write it as follows
4) pH scale.
When the concentration of H+ is high, the solution is acidic. H+ lowers the pH of the solution.
Option D.
Answer:
the rate of a reaction is measured by how fast a REACTANT is used up or how fast a PRODUCT is formed
Answer:
5.3 atm
Explanation:
We can solve this problem using the equation of state for an ideal gas, which states that:
where
p is the pressure of the gas
V is its volume
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
For a gas undergoing a transformation, n and R remain constant, so the equation can be written as
For the gas in this problem we have:
is the initial temperature of the gas
is the final temperature
is the initial pressure
, as the volume is decreased by 40.0%
Solving for , we find the final pressure of the gas:
2,16·10²⁴ = 21,6·10²³
---------------------------
6,02·10²³ atoms ------ 1 mole of Ag
21,6·10²³ atoms ------ X
X = 21,6·10²³/<span>6,02·10²³
<u>X = 3,588</u> moles of silver
