Use the state equation for ideal gases: pV = nRT
Data:
V = 88.89 liter
n = 17 mol
T = 67 + 273.15 = 340.15 K
R = 0.0821 atm * liter / (K*mol)
=> p = nRT / V = 17 mol * 0.0821 (atm*liter / K*mol) * 340.15 K / 88.89 liter
p = 5.34 atm
Answer: p = 5.34 atm
The mole of ammonia in this chemical equation is 0.36933 moles of NH3... I hope it helped? :)
Answer:
Cl2, Chlorine molecule has a boiling point closest to that of argon.
This is because Chlorine is made up of discrete and simple molecules making up a simple molecular structure. The molecules associate through weak van der waal's forces of attraction hence low boiling point.
HCl <em>has</em><em> </em><em>strong</em><em> </em><em>hydrogen</em><em> </em><em>bonds</em><em>.</em>
F2 <em>is</em><em> </em><em>very</em><em> </em><em>small</em><em> </em><em>hence</em><em> </em><em>strong</em><em> </em><em>forces</em><em> </em><em>of</em><em> </em><em>attraction</em><em>.</em>
HF <em>has</em><em> </em><em>strong</em><em> </em><em>hydr</em><em>ogen</em><em> bonds</em>
Answer:
3. A catalyst can convert an endothermic reaction into an exothermic reaction.
Explanation:
<em>What is NOT true for a catalyst? </em>
<em>1. A catalyst increases the rate of a chemical reaction by decreasing activation energy.</em> TRUE. A positive catalyst increases the reaction rate by decreasing the activation energy.
<em>2. A catalyst is not consumed in chemical reactions.</em> TRUE. A catalyst is recovered unaltered at the end of the reaction.
<em>3. A catalyst can convert an endothermic reaction into an exothermic reaction.</em> FALSE. A catalyst cannot modify the enthalpy of a reaction.
<em>4. A catalyst may be used in the solid, liquid or gaseous phase.</em> TRUE. If the catalyst is in the same phase as the reaction, the catalysis is homogeneous. Else, the catalysis is heterogeneous.
