<span>1. Gaseous acetylene (C2H2) reacts with oxygen gas to form gaseous carbon dioxide and gaseous water.
2. Chlorine gas reacts with aqueous potassium iodide to form solid iodine and aqueous potassium chloride.
3. Solid lithium oxide reacts with liquid water to form aqueous lithium hydroxide.
4. Gaseous carbon monoxide reacts with oxygen gas to form carbon dioxide gas.</span>
Molar mass KBr = 119 g/mol
Volume in liters: 250.0mL / 1000 => 0.25 L
n = M x V
n = 1.20 x 0,25 => 0.3 moles of KBr
Therefore:
1 mole KBr ----------- 119 g
0.3 moles KBr -------- ??
0.3 x 119 / 1 => 35.7 g of KBr
Hope that helps, pls double check tho :)
Answer:
C2O42–(aq)
Explanation:
This accepted hydrogen from H3O (hydronium) so it is a Bronsted-Lowry Base.
