(alpha)-Synuclein is a protein that makes membranes, including vesicles bend. It can bend spherical vesicles into tube-like shapes called tubules. The molecular weight of (alpha)-synuclein is 15,400 g/mol.
The standard cell potential of the zinc-air battery is 1.65V. If at 25 dgrees celsius the partial pressure of oxygen in the air diffusing through its cathode is 0.21 atm.
Calculate the mass percent composition of carbon in each the following carbon compounds. C4H10 C6H10 C8H13O5N
A reaction was conducted in benzene as the solvent. Because the reaction was very exothermic, the mixture was cooled in a salt-ice bath. This was a bad choice. Why?
When a mixture of 12.5g of acetylene (C2H2) and 12.5g of oxygen (O2) is ignited, the resultant combustion reaction produces CO2 and H2O
What is the percent hydrogen (H) by weight of a solution containing 53.5mL of CH3COCH3? The density of acetone is 0.788 g/mL
If none of the available reagents can be used for this purpose, then identify another reagent from the table that could be used. For each reagent you've identified, write down a balanced chemical equation for the reaction that occurs.
