Imagine you live in a universe where the electron is allowed four different spin values for the spin qauntum number + 1/2, -1/2, +1/4, and -1/4. Also you only have 36 known elements. Atomic numbers 1-36.Only the pauli Exclusion principale stays the same. 1. If the elements symbol are the same for those 36 elements as they are in our universe, what would the noble gases be? 2.Which elements contain first d electron.
An experiment requires 44.0 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?
need to generate ammonia from ammonium chloride to use in a reaction. should you use sodium bicarbonate or sodium carbonate?
What is the volume (L) of a sample of gas when 4.50 grams of H20(g) and 35.0g of Xe(g) at 650mmHg are mixed at 200 degrees celsius
calculate the vapor pressure of a solution of glycerol of 265ml in 3.80x10^2ml of H2O at the normal boiling point of H2O
Which one is true or false f) HCLO4 is an oxoacid g) the name of HCLO4 is chloric acid i) in the redox reaction 4fe(s) + 3O2 (g) ---2Fe2O3(s) Fe is oxidized and oxygen is reduced
Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written: 2HCl(aq)+Na2Co3(aq) --- 2NaCl(aq)+H2O(I)+CO2(g)
You are given trhat 0.01 m aqueous solutions of each of the given solution as, C6H12O6, K3PO4, CaCl2 , NaI you jutst need to place the given solutions in order of increasing change in the freezing point of the solution.
You have a volume of 100 L at a concentration of 100 PPM of benzene. If you later sampled from this known concentration at a temperature of 15° C
what is the vapor pressure of ethanol at 290 K when heat of vaporization is equal to 38.56 kJ/mol and the normal boiling point is 351.4?
How do I know what the theoretical size is? I can make an estimate using the gel electrophoresis and compare the intensity of my pcr band with my ladder to make an estimation but how do I know the theoretical size
Predict the order for increasing binding energies of the C(1s) electron for the following compounds giving your reasoning.
The H2O molecules above and below the equatorial plane are more loosely bound. For convenience this ion is often written as Cu^2+(aq) Addition of NaOH to the Cu^2+ (aq) solution causes a precipitate of Cu(OH)2. write a balanced equation regarding ..
