Answer:
Number of moles of sodium reacted = 0.707 moles
Explanation:
P(H₂) = P(T) – P(H₂O)
P(H₂) = 754 – 17.5 = 736.5 mm Hg
Use the ideal gas equation which
PV= nRT, where P is the pressure V is the volume, n is the number of moles R is the Gas Constant and T is temperature
<u>Re- arrange to calculate the number of moles and using the data provided</u>
n = P x V/R x T
n =736.5 x 8.77/62.36367 x (mmHg/mol K) x (20 + 273)
n = 0.35348668
n = 0.353 moles H₂
<u>from the equation we know that</u>
0.353 mole H₂ x 2mole Na/1mole H₂, So
0.353 x 2 = 0.707 mole Na
The number of moles of Sodium metal reacted were 0.707 moles.
Answer:
mettaliods
Explanation:
It has the both property of metal and non metal so it is called mettaliod.
Given that seawater freezes at a lower temperature than pure water because of the salts dissolved in it.

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.
