The concentration of the basic solution is determined by:
N = (number of moles / volume of solution)
number of moles = 1.09 x 10^-2 mol
volume of solution = 1 liter
N of basic solution = 1.09 x 10^-2 mol / 1 liter
N = 1.09 x 10^-2 mol/L
The initial concentration of Zn (OH)2 is 0; the basic solution is 1.09x10^-2 M, then the concentration of OH in the final solution is 1.09x10^-2 M
Use the drop-down menus to select the correct answer for each statement. the correct answers are......
Current is the independent variable.
Voltage is the dependent variable.
This graph shows a(an) direct relationship.
A current of 0.04 A gives a voltage of 5.5 V.
A voltage of 2 V corresponds to a current of 0.014 A.
Answer:
The correct option is;
b. The particles are positively and negatively charged, have high compressibility, and spread out to fill a container
Explanation:
Plasma are gases that contain positively and negatively charged particles. Therefore, plasma flow drift in space such that plasma. like gases has no characteristic shape or volume but takes the shape and fills the entire volume of a container in which it is placed
Other characteristics of plasma are that plasma is a conductor of electricity and magnetic fields can therefore exist in plasma due to the fact that plasma are made of atoms in which part or all of the electrons have been removed leaving the ions to roam freely in a container.
Answer:
pOH = 5
pH = 9 → Solution is basic
Explanation:
We need to know that:
pH + pOH = 14
< 7 ⇔ pH = 7 ⇔ > 7
Acidic Neutral Basic
pOH = - log [OH⁻] → - log 9.8×10⁻⁶ = 5.00
pOH = 5
pH = 14 - 5 = 9
