When relatively small amounts of magnesium burn, the fires are extinguished using commercially available dry powder.
Why might this fire rekindle days later as someone tries to remove the residue with water? What chemical process is involved here?
Just as you are about to start making them, you get a call saying that the number of people coming to the meeting has doubled! Your original recipe called for three eggs. How many eggs do you need to make twice as many muffins
The following data apply to 25oC and 100kPa. Assume the specific volume Vs, and Kt are constant with respect to pressure changes. delta G(graph) = 0
If the measured gas pressure in a collection flask during a gas-forming reaction was determined to be 1.44 atm, and the atmospheric pressure that day was measured as 0.95 atm.
A cell consisting of a saturated calomel electrode as well as a lead ion-selective electrode developed a potential of -0.4812 V when immersed in 50.00mL of a sample. A 5.00-mL addition of standard 0.02500 M lead solution caused the potential to sh..
Write down the balanced chemical equation when Fe 3 O 4 reacted with carbon monoxide and calculate mass of carbon dioxide that will be produced in this reaction if 234 g carbon monoxide is reacted with excess Fe 3 O 4 ?
a small bubble rises from the bottom of a lake where the temperature and pressure are 4oc and 3.0 atm to the waters
Vinegar must contain at least 4% acetic acid (0.67M). A 5.0mL sample of commercial vinegar required 33.5mL of 0.100M NaOH to reach the equivalence point. Does the vinegar meet the legal limit of 4% acetic acid
Draw the most stable form of the major mixed Claisen product formed in the reaction.
In a lab you need 1.0M, 0.1M, and 0.05M Cu2+. How could you make 50.0mL of each of these three solutions with only 10.0g of Cu(NO3)2 available
Protein Sequencing Question. Determine the sequence of a peptide consisting of 14 amino acids on the basis of the following data
Write a balanced chemical equation for the reaction of 4-Nitrobenzaldehyde and sodium borohydride (NaBH4). If 0.21 g of 4-nitrobenzaldehyde dissolved in 10 mL of methanol is mixed with 0.14 g of sodium borohydride, what is the theoretical yield?
Problem- An experimenter makes up a solution of 0.310 mol Na3PO4, 0.100 mol Ca(NO3)2, and 0.150 mol AgNO3 in 4.000 liters of water solution. Note any precipitation reactions that occur, write a balanced chemical equation for each. Then calculate t..
