Answer: The oxidation state of selenium in SeO3 is +6
Explanation:
SeO3 is the chemical formula for selenium trioxide.
- The oxidation state of SeO3 = 0 (since it is stable and with no charge)
- the oxidation number of oxygen (O) IN SeO3 is -2
- the oxidation state of selenium in SeO3 = Z (let unknown value be Z)
Hence, SeO3 = 0
Z + (-2 x 3) = 0
Z + (-6) = 0
Z - 6 = 0
Z = 0 + 6
Z = +6
Thus, the oxidation state of selenium in SeO3 is +6
<span>The concentration of pb2+ = 1.00mg/ml
Diluted Solution is 6.0 x 102 ml = 612 ml
Volume of the concentration of pb2+ is 0.054 mg/l is v
(vL)(1.00mg/ml) = (.612L)(0.054mg/l)
Volume = 0.033048L
Volume of the concentration of pb2+ is 0.054 mg/l = 33.048 ml.</span>
Answer:
When secondary bile salts (or acids) lack a OH, they are reabsorbed
Explanation:
The lost of a hydroxyl group (OH) in the bile salts structure means less hydro solubility. Thus, they are not eliminated, conversely, the are reabsorbed for intestine and they go back to the liver.

The law that regulates access to information about chemicals used in workplaces is called OSHA's Hazard Communication Standard.
<h3>What is the OSHA Hazard communication standard?</h3>
In a workplace, all employees should be introduced to dangers connected with exposure to hazardous chemicals. They should get a Material safety data sheet (MSDS) from the manufacturers about the chemicals. Employees can file a complaint in their local OSHA office if they think that their employer isn’t complying with the OSHA STANDARDS and for employees’ safety, the name of the complainant can be kept a secret. It is made for the safety of employees by enforcing some standards and rules.
