  • 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 #9b627 + Example - Socratic
    Changes in state are physical changes Let's take water as an example H2O In the gaseous state, we sometimes call it steam or water vapor; it's chemical formula is still H2O In the liquid state and in the solid state (ice), the chemical formula is H2O In a physical change, the original substance is still there - it may be in a different state or shape, but there are no new substances
  • Why is H_2 not very soluble in water? | Socratic
    The trade in energy sucks for H2 (but not so much for water), so the H2⋯H2O interaction is highly unfavored for H2, compared to the H2⋯H2 and H2O⋯H2O interactions So, H2 is very poorly soluble in water Its solubility at 1 atm at 20∘C is 0 00016 g H2 100 g water
  • Answers created by Paul - Socratic
    How do you write the formula of an ionic compound? What elements are liquid at room temperature? What do the subscripts mean in a chemical formula? How can I balance this equation? ____ H2 + ____ O2 ---> ____ H2O Is HCl a dipole dipole? Why is the rate of reaction fastest at the beginning? How do particles behave in the three phases of matter?
  • Complete combustion of C14H18O7 to CO2 and H2O. You have 315 . . . - Socratic
    Complete combustion of C14H18O7 to CO2 and H2O You have 315 0000 grams of C14H18O7 How many grams of O2 are required? How many grams of CO2 are generated? How many grams of H2O are generated? Chemistry
  • Writing word equations as chemical equations and balance . . . - Socratic
    magnesium oxide = MgO Hydrochloric acid = HCl Magnesium Chloride = MgCl2 Water = H2O MgO + 2HCl rarr MgCl_2 + H_2O Beryllium chloride = BeCl2 Silver nitrate = AgNO3 Beryllium nitrate = Be(NO3)2 Silver Chloride = AgCl BeCl_2 +2 AgNO_3 rarr Be(NO_3)_2 + 2AgCl
  • What are the names of the two molecules plants need to . . . - Socratic
    Two molecules that plants need to absorb to perform photosynthesis are CO2 and H2O
  • Question #862f2 - Socratic
    2HCl +CrO3 → CrO2Cl2 + H2O If you add these equations together (and balance them out), you'll get the chemical equation that describes the overall reaction I think that some chlorine gas can actually be produced here as a side-product of the reaction, but even if that happens this reaction will still qualify as your answer
  • Stoichiometry with Acid and Base Dissociation - Socratic
    What is the balanced chemical equation of Ca2 +H2O >C2H2 + Ca (OH)2? What is the balanced chemical equation that describes the dissociation of the strong base magnesium hydroxide, Mg (OH)2 in water? Can you write the balanced chemical equation that describes the dissociation of the strong base of magnesium hydroxide in water?
  • How much heat is released when 100. 0 mL of water is called . . . - Socratic
    ~~4 0xx10^4 "J" are released The equation to use is: q=mcDeltaT, where: q is heat energy, m is mass, c is specific heat capacity, and DeltaT is change in temperature DeltaT=T_"final"-T_"initial" The density of water is "1 g mL", which means that every "mL" has a mass of "1 g" Therefore, "100 0 mL" of water has a mass of "100 0 g" Since there is no mention of a phase change, I'm assuming
