CH4+O2 = CO2+2H2O
C-1 C-1
O-2 O-4
H-4 H-4
CH4+<u><em>2 </em></u>O2 = CO2+2 H2O
C-1 C-1
O-2-4 O-4
H-4 H-4
You add a 2 in front of the O2 on the reactant side so the Oxygen can balance on the Product side
Hello!
the correct setup is shown at bottom of your question
we get
total moles*(1/102.0 g/mol)= total grams Al2O3
hope this helps. any questions please ask. thank you kindly
Answer: Physical changes are related to physical properties since some measurements require that changes be made. Melting Point: As solid matter is heated it eventually melts or changes into a liquid state at the melting point. Ice (a solid form of water) melts at 0 oC and changes to the liquid state.
Explanation:
Answer:
Physical change
Explanation:
In chemistry, a physical change is that change that does not involve the formation of new products as there is no modifications to the chemical structure of the substance involved. There is no change in the chemical composition of the involved substance, rather a physical change in properties including shape, size, density, state of matter etc. A physical change is also easily reversible.
In this case, a physical change involving change of state is concerned. There is a change in state from liquid to gas but the chemical composition of the water molecules are not altered.
