A reaction occurs between sodium hydroxide (NaOH) and carbon dioxide (CO2) to give sodium carbonate (Na2CO3) and water.
Balance the equation
How many grams of sodium carbonate is formed from the reaction of 74.0g of sodium hydroxide and 44.0g CO2?
How many grams of each material is present after the reaction?
How could you use a conductometric titration to determine the molarity of either reacting solutions, assuming you knew the concentration of one
The normal boiling and freezing points of substance X are 87.3 K and 84.0 K respectively. The triple point is at 82.7 K and 0.68 atmosphere. a. Draw a phase diagram for substance X. Label the regions in which the s,l, and g phases are stable.
Determine the energy change associated with these changes in state: a. 138g of steam condenses,b. 261mg of solid mercury melts,c. 8.36g of rubbing alcohol freezes d. 52g of liquid methane boils
Human and chameleon insulins have the same amino acid sequence, with the exception of six amino acids, as shown below. Is the pI of human insulin lower, higher, or the same as that of chameleon insulin?
how do you know weather it undergoes the E1 mechanism or the E2 mechanism?
if I have .42N NaOH and the stoiometry between Oxalic acid and Naoh is 1:2 then does that mean i do .42/.5=mol Oxalic acid * vol of titrations = molarity of oxalic acid
What is the net redox reaction that occurs when Cu comes into contact with acidic K2Cr2O7? (b) What is the E cell for the reaction
The bromocresolgreen end point of the titration was reached after the addition of 30.00mL of hydrochloric acid solution. Calculate the concentration of the acid solution
What is the hybridization of each carbon for the following structure? Please explain each one and provide the line structure. Supposedly there should be two hybridized sp2 and two hybridized Sp3
The half life of oxygen-19 is only 29 seconds. Lets say we somehow instantly make a Liter of O-19 in a reactor. So at t = 0 we have 1 Liter of this isotope. What fraction of the O-19 isotope would be present after 5 seconds?
