Answer: The vapor pressure of Fe at is 465 mm Hg
Explanation:
The vapor pressure is determined by Clausius Clapeyron equation:
where,
= initial pressure at = 400 mm Hg
= final pressure at = ?
= enthalpy of vaporisation = 351 kJ/mol = 351000 J/mol
R = gas constant = 8.314 J/mole.K
= initial temperature = 2890 K
= final temperature = 2920 K
Now put all the given values in this formula, we get
Thus the vapor pressure of Fe at is 465 mm Hg

2H2 + O2 ====> 2 H2O (water ) is the equation sooooo....
Answer:
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding
Explanation:
Methylisothiazolinone, MIT, or MI, is the organic compound with the formula S(CH)2C(O)NCH3. It is a white solid. Isothiazolinones, a class of heterocycles, are used as biocides in numerous personal care products and other industrial applications.
