Answer:
4
Explanation:
Data obtained from the question include:
[H3O+] = 0.0001 M
pH =?
pH is the negative logarithm of the hydrogen ion or hydronium ion. It is written as:
pH = - Log [H3O+]
Now inputing the value of [H3O+] into the equation above, the pH value can be obtained as follow illustrated below
pH = - Log [H3O+]
[H3O+] = 0.0001 M
pH = - Log 0.0001
pH = 4
Therefore, the pH of the solution is 4.
Answer:
.4586M
Explanation:
It's simple, just devide the mol value by the volume value. So 3.66mol/7.98L=.4586M
Answer:
467.000g AICI3 to mol AICI3
Explanation
I think the correct answer is Hemoglobin. Hemoglobin is necessary for the transport of oxygen by an erythrocyte. It is a protein molecule found in red blood cells made of four subunits; two alpha subunits and two beta subunits. This protein is responsible for carrying of oxygen to body cells and tissues, and carbon dioxide to the lungs.
Answer:
2 AsCl₃ + 3 H₂S → As₂S₃ + 6 HCl
Explanation:
When we balance a chemical equation, what we are trying to do is to achieve the same number of atoms for each element on both sides of the arrow. On the right of the arrow is where we can find the products, while the reactants are found on the left of the arrow.
We usually balance O and H atoms last.
AsCl₃ + H₂S → As₂S₃ +HCl
<u>reactants</u>
As --- 1
Cl --- 3
H --- 2
S --- 1
<u>products</u>
As --- 2
Cl --- 1
H --- 1
S --- 3
2 AsCl₃ + H₂S → As₂S₃ +HCl
<u>reactants</u>
As --- 2
Cl --- 6
H --- 2
S --- 1
<u>products</u>
As --- 2
Cl --- 1
H --- 1
S --- 3
The number of As atoms is now balanced.
2 AsCl₃ + 3 H₂S → As₂S₃ +HCl
<u>reactants</u>
As --- 2
Cl --- 6
H --- 6
S --- 3
<u>products</u>
As --- 2
Cl --- 1
H --- 1
S --- 3
The number of S atoms is now equal on both sides.
2 AsCl₃ + 3 H₂S → As₂S₃ + 6 HCl
<u>reactants</u>
As --- 2
Cl --- 6
H --- 6
S --- 3
<u>products</u>
As --- 2
Cl --- 6
H --- 6
S --- 3
The equation is now balanced.
