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 ...
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
Complete combustion of C14H18O7 to CO2 and H2O. You have 315 ... - 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 ...
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 ...
