Answer:
The answer to your question is: letter B
Explanation:
Reaction
Cr2O3(s) + 3CCl4(l) ⇒ 2CrCl3(s) + 3COCl2(g)
From the information given and the reaction, we can conclude that:
Green solid = Cr2O3 (s) "s" means solid
Colorless liquid = CCl4 (l) "l" means liquid and is the other reactant
Purple solid = CrCl3(s) CrCl3 is purple and "s" solid
Then, as a green specks remains it means that the excess reactant is Cr2O3, so, CCl4 is the limiting reactant.
Grams. It is a smaller unit.
Water boils when its vapor pressure equals the prevailing atmospheric pressure over the water. In order for water to boil at 50 ºC, the pressure over the water would need to be reduced to a point greater equal to the vapor pressure of the water (92.5 torr).
Answer:
Decomposition
Explanation:
A molecule breaks up into 2 simpler molecules
Explanation:
The ideal gas law or equation can also be reduced to the general gas law or the combined gas law.
Let us assume that n = 1;
From PV = nRT ideal gas law
= R (constant) if n = 1
Therefore, the combined gas law is;
The expression is a combination of Boyle's Law and Charles's law.
