Problem- How many grams of H2 are needed to react with 47 grams of O2, given the reaction: 2 H2 (g) + O2 (g) --> 2 H2O (l)
Determine the solution for the above problem express your work in detail
Define milk of Magnesia is a suspension of magnesium hydroxide in water. A common medicine, it is frequently used as an antacid for the reason that it neutralizes hydrochloric acid in the stomach
The heat of vaporization of water in this temperature range is 2.40 kJ/g. The heat capacity of water is 4.184 J/g.K. Answer in grams of water
Presume the heat is achieved completely by the air at a constant density of 1.239mg ml-1, absorbing heat. The outside temperature is -15C. Explain how much heat is extracted from the outside and how much work must be performed
What is the HCl concentration if 69.7 mL of 0.350 M NaOH is required to titrate a 30.0 mL sample of the acid?
many enzymes are inhibited irreversibly by heavy-metal ions such ashg2 cu2 or ag which can react with essential
Explain what is the theoretical yield of adipic acid (MW= 146.14) while only .0224g of this product were recovered at end of experiment
how much heat is required to convert 27.0 g of ethanol at 23 c to the vapor phase at 78 c in kj? ethanol c2h5oh boils
