PH = -log [H⁺] ←←[log without a specified base means log base 10]

and if you want to use the hydronium ion concentration then use pH = -log [H₃O⁺] 

either way the calculation is the same: 

They give that a 0.1 M solution of NaHCO₃ has a hydrogen ion concentration of 4.0 x 10^(-9) 

so pH = -log (4.0 x 10^(-9)) 

pH = 8.4

Water molecules are constantly moving in Ice they move slower and are more tightly packed together and move at a slower pace to lower the freezing point you would have to find a solute that makes it harder for water to form crystals

If oxygen with an electronegativity of 3.5 were to make a chemical bond with lithium, electronegativity of 1.0, what kind of bon

sergejj [24]

Answer:

Ionic.

Explanation:

Elements with higher electronegativity values are better at attracting electrons in a chemical bond.

A chemical bond is considered "ionic" if the electronegativity difference between the two bonding atoms is greater than $1.8$ .
Otherwise, this chemical bond is considered "covalent".

In this example, the difference between the electronegativity of oxygen and lithium is $3.5 - 1.0 = 2.5$ . Since $2.5 > 1.8$ , the bond between the two elements would likely be ionic.

It is possible to reach the same conclusion based on the fact that lithium is a metal while oxygen is a nonmetal. When metal elements react with non-metal elements, the product is typically an ionic compound- with ionic bonds between the atoms.

4.07 x 10-17 (5.6 x 10") (5.8 x 105)

Andrej [43]

4.07 x 10-17 = 23.7
(5.6 x 10”) (5.8 x 105)= log(100)
log(7)
Hope this helped
