Find the pH and the pOH of the solution

1 answer:

5 0

Ok so the PH for each solution will be
1.) 1.638 2.) 5.2 3.) 12.524
This is found using the formula: pH = - log [H3O+].
And the pOh for each one will be
1.) 12.362 2.) 8.8 3.) 1.4763
This is found by the formula pOH = -log10[OH-]
Hope this is useful

Naya [18.7K]

Hypotheisis is just like an initial building block for a building. The true statements about hypothesis among the given are-

First guess- hypothesis is a proposed explanation for something which is observed. Thus the explanation is just a guess and not a proved one.
An initial idea which is assumed to be true - The whole experiment or research is based on an assumption which is supposed to be true and the scientist works to prove that true.

A 0.5 mol sample of N2 is in a 6L container at 2 atm. what is the temperature of the gas in K

Andreas93 [3]

Answer:

300 K

General Formulas and Concepts:

Atomic Structure

Diatomic Elements
Moles

Gas Laws

Ideal Gas Law: PV = nRT

P is pressure
V is volume
n is moles
R is gas constant
T is temperature

Explanation:

Step 1: Define

Identify variables

[Given] n = 0.5 mol N₂

[Given] V = 6 L

[Given] P = 2 atm

[Given] R = 0.0821 L · atm · mol⁻¹ · K⁻¹

[Solve] T

Step 2: Solve for T

Substitute in variables [Ideal Gas Law]: (2 atm)(6 L) = (0.5 mol)(0.0821 L · atm · mol⁻¹ · K⁻¹)T
Multiply [Cancel out units]: 12 atm · L = (0.04105 L · atm · K⁻¹)T
Isolate T [Cancel out units]: 292.326 K = T
Rewrite: T = 292.326 K

Step 3: Check

Follow sig fig rules and round. We are given 1 sig fig as our lowest.

292.326 K ≈ 300 K

A 4.55 l sample of water contains 0.115 g of sodium ions. determine the concentration of sodium ions in ppm if the density of th

Slav-nsk [51]

When one talks about ppm in a liquid solution someone means mg/L so we would not be using the density. This usually means ug/g or mg/kg 0.115 g Na^+ * 10^6 ug/1 g = 115000 ug/g 4.55 L * 1000 mL/1L = 4550 mL Concentration of Na^+ in ppm: 115000 ug/g /4550 mL = 25.27 pm of sodium ion

An element belongs to group 17 of the periodic table. This element is most likely a ____. A solid of this element would have a _

storchak [24]

Answer:

An element that belongs to group 17 of the periodic table is a halogen, and will have physical and chemical characteristics like that of nonmetals.

Explanation:

Halogens are nonmetals, and include five elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They are all nonmetals, and are quite toxic.

Halogens become darker as you go down the group. Fluorine is a very pale yellow, while bromine is red-brown. Halogens have relatively low melting and boiling points as well.
