Answer:
I am not sure but i think it is 5 grams
Explanation:
because the total mass= 5g
so it is a physical change so no new substance is formed
so the total mass = total mass of all the broken pieces
The crude oil is heated in a process of fractional distillation (note: you can research this online if you require more detail) and this process causes different hydrocarbons to condense at different heights up the distillation column. They will therefore run down the side of the column and into different areas depending on their boiling point.
I want to see how the temperature of water affects the speed of rusting. What is the Independent Variable?
The Independent Variable is the temperature of water.
The molar mass of a 0.314-gram sample of gas having a volume of 1.6 l at 287 k and 0.92 atm. is 5.23 gram.
<h3>What is an Ideal Gas ?</h3>
An Ideal Gas is a law for ideal gas which states that the product of Pressure and Volume is equal to the product of the moles of sample, universal gas constant and temperature.
PV = nRT
The given data in the question is
Pressure = 0.92 atm
Volume = 1.6 l
Temperature = 287 K
0.92 * 1.6 = n * 287 * 0.082
n = 0.06 moles
0.06 = 0.314 / molecular weight
molecular weight = 0.314/0.06
Molecular weight = 5.23 gm
Molar mass = 5.23 gm.
The temperature and pressure conditions at which the gas behaves like an ideal gas is 273 K and 1 atm.

Answer:
Decomposition
Explanation:
A decomposition reaction is when a compound breaks down into simpler substances.
in our case Ammonium hydroxide requires an input of energy to obtain Ammonia gas and water.
