Chemical properties can only be analyzed by putting the substance through a chemical reaction, such as combustion.
Physical properties can be analyzed without altering the substance chemically. With that in mind:
Boiling point: physical
Density: physical
Ductility: physical
Heat of combustion: chemical
Answer:
0.11
Explanation:
This equation is not balanced because there is an unequal amount of O's on both sides of the equation. The left hand side has 4 P's and the right hand side has 4 P's. So the P atoms are balanced. The left hand side has 2 O's and the right hand side has 10 O's.
To fix this unbalanced equation a 5 in front of the O2 on the left hand side is added to make 10 O's on both sides resulting in
P4 + 5O2 = 2P2O5
The equation is now balanced because there is an equal amount of substances on the left and the right hand side of the equation.
C)crabon,oxygen and calcium
Answer: Concentration of at equilibrium = 0.08 M
Concentration of at equilibrium =0.08 M
Concentration of = 0.64M
Explanation:
Moles of = 4.00 mole
Volume of solution = 5.00 L
Initial concentration of =
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For the given chemical reaction:
Initial conc. 0.8 M 0 M 0 M
At eqm. conc. (0.8-2x) M (x) M (x) M
The expression for is written as:
Concentration of at equilibrium = x M = 0.08 M
Concentration of at equilibrium = x M = 0.08 M
Concentration of = (0.8-2x) =
Answer:
The reaction type is double displacement
