Every antacid contains one or more ingredients capable of reacting with excess stomach acid (HCl). The neutralization products (among others) are CO2 and/or HO2. Write net ionic equations to reprsent the neutralizing action of the following antacids: (assume that the antacid starts out as a solid).
a) Tums (calcium carbonate)
b) Milk of magnesia (magnesium hydroxide)
c) Alka-Seltzer (sodium hydrogen carbonnate)
calculate the equilibrium concentrations of H2 and Br2 and HBr? Calculate Kc
Determine if the concentration of formaldehyde and methanol as measured in water will convert to its relative organic acids? If there is a measured concentration of formaldehyde and methanol in a 1000L solution of water at temperature = 180 degrees..
Predict whether creatine kinase will operate in the direction of ATP synthesis or phosphocreatine synthesis at 25 degrees C given that:
Concentrated stock HCl has a molecular weight of 36.46 and contains 32g of salt for every 100g of acid (termed as 32% w/w). To prepare molar solutions %w/w must be converted into %w/v by considering the density of stock HCl which is 1.16.
