  • Question #00338 - Socratic
    We're asked to find the molarity of the HCl in the gastric juice with some given titration data First, let's write the balanced chemical equation for this neutralization reaction: NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l) Here's a hint we can use only in the special case of one-to-one molar ratios: M 1V 1 = M 2V 2 where M 1 and M 2 are the molarities of the two solutions V 1 and V 2 are the
  • Question #54b11 - Socratic
    The reaction is carried out at pH 8, so we must balance in basic solution I find it easiest to balance the equation as if it were in acid solution and then convert it to basic medium Step 1 Write the two half-reactions CH3CH2COO- → CH3COO- +HCO- 3 S → HS- Step 2 Balance all atoms other than H and O Done Step 3 Balance O by adding H2O molecules to the deficient side CH3CH2COO

    An equilibrium constant Keq is written so that its mass action expression uses the stoichiometric coefficients in the reaction in its exponents (except if they are 1) reactant 2H2O(g) ⇌ products 2H2(g) + 1O2(g) The mass action expression is written with products on top and reactants on the bottom Keq = mass action expression [H2]2[O2] [H2O]2 Remember to exclude the pure liquids and solids
  • Is geothermal energy renewable or nonrenewable energy? - Socratic
    Geothermal energy is renewable Geothermal energy is renewable because the Earth has retained a huge amount of the heat energy that was generated during formation of the planet In addition, heat is continuously produced by decay of radioactive elements within the Earth Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be re-injected, making it a
  • Why can you only add oleum to water to get SO2 (g . . . - Socratic
    Why can you only add oleum to water to get SO2 (g) industrially instead of adding SO3 (g) to H2O (l) immediately?
  • Question #15b51 - Socratic
    a=2sqrt489 Let r be the inradius of the triangle, given that the area of the incircle =163pi, => pir^2=163pi => r=sqrt163 Formula for inradius (r) of a triangle : r=(2A) p, where A and p are the area and the perimeter of the triangle, respectively Recall that area A of an equilateral triangle is : A=(sqrt3a^2) 4, where a is the side length of the equilateral triangle => r=(2A) p=((2*sqrt3a^2
