The chemical reaction of SiCl2→ Si +Cl2 is
A decomposition reaction
<u><em>Explanation</em></u>
- <u>A decomposition reaction</u> is type of chemical reaction which involve breaking down a compound into smaller compounds or individual elements.
- <em>SiCl2→ Si +Cl2 is a decomposition reaction because SICl2 is broken down into Si and Cl2</em>
- Decomposition reaction often involve input of energy in form of heat to break down compounds
Answer:2.27 g H2O
Explanation:
Step 1. Get the limiting reagent
1.24 atm of H2 would react completely with 1.24 x (1/2) = 0.62 atm of O2, but there is more O2 present than that (0.98). O2 is in excess and H2 is the limiting reactant.
If the reaction goes to completion:
(1.24 atm H2) x (2 mol H2O / 2 mol H2) = 1.24 atm H2O vapor
n = PV / RT = (1.24 atm) x (2.5 L) / ((0.08205746 L atm/K mol) x (28 + 273)K) = 0.126 mol H2O
(0.126 mol H2O) x (18.01532 g H2O/mol) = 2.27 g H2O
The correct answer is L, solid to gas; given that you meant after the change the substance can fill the container entirely
Answer: Strawberries liquefied in a blender
Explanation:
You can tell it is more dense because it sinks
if it floats it's less dense
