Answer:
0.362 moles
Explanation:
Mass of butane = 21g
Molar mass of carbon = 12g / mol
Molar mass of hydrogen = 1g/mol
Molar mass of butane ? = [(12*4) * (1*10)]
Molar mass of butane = 58g / mole
Number of moles = mass of molecules / molar mass of molecule
Number of moles = 21 / 58
Number of moles of butane = 0.362 moles
The number of moles in 21g of butane is 0.362 moles
Answer:
The equilibrium will shift to produce less ammonia
Explanation:
According to Le Chatelier's principle, the reaction will try to oppose anything that is done on it, if it was at equilibrium.
When the concentration of H2 is decreased, you are decreasing the concentration of hydrogen so the reaction tries to increase the concentration of hydrogen by breaking down the ammonia on the products side. This will decrease the output of ammonia
Answer:
Liquid
Explanation:
It is liquid because liquid will always take shape of the container. For example, take a square container and a round cup, and a 1/d of water, put it in the square container and it will take the shape of that container, but take the SAME water and put it in the cup and now its in a circle cause it is taking shape.
Answer:
yes, the law of conservation of mass hold true in this case burning magnesium strip is explained by this equation 2 Mg (s) + O2 (g) -> MgO (s)So the lighter magnesium, after reacting with oxygen in air, forms the heavier magnesium oxide. molar mass of magnesium and magnesium oxide are 24g and 40g respectively. So the same ratio 24:40 (i.e. 3:5) is maintained in the given masses of 48g and 80g, which means mass is conserved in the reacion.
Explanation:
I can form two compounds if I combine calcium, hydrogen and oxygen in five minutes.
<h3>What is a compound?</h3>
A compound is formed by the combination of atoms. It is important to note that the same atoms can be combined in different ways to produce new compounds.
