Answer:
6.37 L
Explanation:
- Used combined gas law. Get rid of temperature since it is constant. (You could also keep it and get the same answer, but it is another step)
- Change C to K
- Change torr to atm
- Hope this helps! I would be glad to give you a step by step explanation. Please let me know if you want help on how to do these types of problems.
Answer:
4.52 grams of potassium chloride
Explanation:
First you need a balanced reaction equation K(s) + Cl₂ (g) --> 2 KCl(s). Since the chlorine gas is said to be in excess all of the potassium will be converted to form potassium chloride. Convert grams of potassium to moles of potassium with the periodic table, then you can convert moles of potassium to moles of potassium chloride with the balanced equation, finally convert moles of potassium chloride to grams of potassium chloride with the periodic table. Set up a dimensional analysis chart to help with conversions
(2.50 grams K) * (<u>1 mole K</u>) * (<u>2 mole KCl)</u> * (<u>35.45 grams KCl</u>)
(39.09 grams K) (1 mole K) (1 mol KCl)
Which equals 4.52440778 grams, with sig figs it should be 4.52 grams of potassium chloride
Answer:
Transition metals can have multiple oxidation states because of their electrons. The transition metals have several electrons with similar energies, so one or all of them can be removed, depending the circumstances. This results in different oxidation states. please mark me as brainellist
