What mass of zinc oxide can be produced from the reaction of 415 g zinc sulfide with 265 g of oxygen gas? The other product is sulfur dioxide.
Methyl alcohol (CH3OH) has a density of 0.793 kg/L. What volume of it is needed to add to water to make 5 liters of 0.250 M solution?
Provide me with your exact logic used to get the answer. A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios.
A voltaic cell consists of a Mn/Mn2+ electrode (E°= -1.18 V) and a Fe/Fe2+ electrode (E°= -0.44 V). Calculate [Fe2+] if [Mn2+] = 0.050 M and Ecell = 0.78 V at 25°C.
Ice cream mix containing 40% total solids is frozen so that half of the original water is made into ice (which is effectively pure water). If the mix contained 12% fat, 16% sugar, and 12% nonfat milk solids
When solid iodine is introduced into an evacuated vessel at 25 degrees Celcius, some of the iodine sublimes. Predict how the enthalpy, entropy, and free energy change in the system
Enantiometrically pure retrosynthesis, There are many ways of making (R)3-ethyl-4-methylpent-1-yne. Explain what enantiomerically pure retrosynthesis is and show
the maximum velocity of the ejected electrons is 3.45 multiplied by 105 m/s. Calculate the binding energy of electrons to the magnesium surface.
How to Name and Define Acids, How can you know that HNO3 is nitric acid and HNO2 is nitrous acid? How do you know the difference in endings?
If 100.0J of energy are added to 25.0g of water at 50 degrees celcius,what will the final temperature of the water be?
If you dilute 25.0 of the stock solution to a final volume of 0.460 , what will be the concentration of the diluted solution?
Ferrocene cannot be nitrated using the conventional HNO3-H2SO4 mixed acid conditions, even though nitration is an electrophilic
High temperature and low pressure low temperature and high pressure none of the above unless a catalyst is present If it's endothermic, it's high temp and low pressure, but does having an exothermic reaction change that?
