Answer:
pH of the HI solution =4.13
.
Explanation:
0.0000734 M concentration of Hl is the same as saying that 7.34 *10-5 moles of H+ ions have been added to solution.
pH of HI = -log[H+]
The -log[0.0000734] =4.1343.
pH of the HI solution =4.13.
Answer:
Attached in the photo.
Explanation:
Hello,
The answers in the attached photo. Just three things:
- In the second point a parenthesis is missing to properly understand the molecule (after the oxygen), nevertheless, I assumed it was an ether.
- In the sixth point, there's a missing hydrogen for it to be an ether as well.
- In the tenth point the second parenthesis is not clear, it seems there's a missing subscript, nevertheless I draw it assuming complete octates.
Best regards.
Answer:
The number of atoms of each elements are same on both side of equation.
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
Answer: 1.8 x 10^1 or the scientific e notation is: 1.8e1
Re-read and go back and look for A & B and then whatever A & B is solve for it and then get your answer
