Calculate the [H+] in a solution that has a pH of 10.36

Chemistry
1 answer:
Pavlova-9 [17]3 years ago
5 0

Answer:

[H+] = 4.365x10⁻¹¹

Explanation:

The pH is a measurement widely used in chemistry. Is used in quality control to determine if a product is good for human or pet consumption. The equation to obtain the pH is:

pH = -log [H+]

To solve [H+]:

10^pH = -[H+]

10^-pH = -[H+]

In the problem:

10^-10.36 = -[H+]

<h3>[H+] = 4.365x10⁻¹¹</h3>

How many moles of atoms are in each elemental sample?
Vlada [557]

Answer:

Moles = mass(m) / Molar mass (M)

A. 1.24g of Zn

m = 1.24g

M = 65.4 g/mol

moles of Zn = 1.24g/ 65.4g/mol

= 0.01896mol

B. 28.1 g Ar

m = 28.1g

M(Ar) = 39.9g/mol

moles of Ar = 28.1g/39.9g/mol

= 0.7043 mol

C. 84.0 g Ta

m = 84.0g

M(Ta) = 181g/mol

moles of Ta = 84.0g/181g/mol

= 0.4641 mol

D. 2.29x10^-2 g Li

m = 2.29x10^-2 g

M(Li) = 6.9g/mol

moles of Li = 2.29x10^-2 g / 6.9g/mol

= 0.0033 mol

Hope this helps

Can someone please help with this I need the answers for the three boxes
denis23 [38]

Answer:

Type: M

Name: Dixytrogen Pentasulfide

Molar Mass:

X*2 = Number * 2 = Number

S*5=32.066*5=160.33

Number + 160.33 = Molar Mass (g/mol).

(The mass for Xytrogen is not present).

Explanation:

Assuming Xytrogen is a non-metal and bonding it with sulfur, another non-metal would make it covalent or molecular.  

The name is from the amount of Xs (being two [Di]) and the amount of Ss (being five [Penta]).

The molar mass is explained above.  You need to multiply the mass of each element by the number of elements present in the compound.  The mass for Xytrogen is not present (as it is a made up element) so I left instructions how to do it once given the mass instruction.

Hope this helps.
