What is the word reaction for Mgs 2H2Og yields MgOH2aq H2g?
Its 0
Which 1.0 liter sample has the greatest mass at STP a CH4g b CL2g c CO2g d H2g?
The sample with the greatest mass at STP would be the one with the highest molar mass, as 1 mole of any substance at STP occupies the same volume (22.4 L). Among the given options, the sample with Cl2 gas (molar mass = 70.9 g/mol) would have the greatest mass.
Does Na H2O NAOHaq H2g obey the law of conservation of matter?
Yes, the equation obeys the law of conservation of matter. The number of atoms for each element is the same on both sides of the equation, indicating that no atoms are created or destroyed during the reaction.
Under the same conditions of temperature and pressure which of the following gases would behave most like an ideal gas 1 Heg 2 NH3g 3 Cl2g 4 CO2g?
A. Of the choices listed, the helium atom is the smallest in both size and mass, and so its behavior is more "ideal." 1.He(g) Of the choices listed, the helium atom is the smallest in both size and mass, and so its behavior is more "ideal."
What is the oxidation half reaction for Fe(s) 2HCl(aq) FeCl2(aq) H2g?
The oxidation half-reaction is: Fe => Fe+3 + 3e-, and the reduction half-reaction is: F2 + 2e- => 2 F-1. For a complete equation, the oxidation half-reaction as written must be multiplied by 2 and added to the reduction half-reaction as written multiplied by 3 to result in an overall reaction of 2 Fe + 3 F2 = 2 FeF3.
What is keq for the reaction 2hclg h2g cl2g?
The equilibrium constant, K_eq, for the reaction 2HCl(g) ⇌ H2(g) + Cl2(g) is equal to the concentration of H2 and Cl2 divided by the concentration of HCl squared, as products are in the numerator and reactants in the denominator.

H2g plus I2g 2hIg has keq equals 0.15 at a certain temperature if h2 equals 0.01 I2 equals 0.02 and hI equals 0.03 what is true about this reaction?
HI will be consumed. The reaction will proceed to the left. More I2 will form.
What is the correct form for the equilibrium constant expression for this reaction H2g plus F2g 2 HFg?
The correct form for the equilibrium constant expression for this reaction is Kc = [HF]^2 / ([H2] * [F2]), where the square brackets denote molar concentrations of each species at equilibrium.
