Like water, the hydrogen carbonate ion (HCO31-) is amphiprotic. That is, it can act like a Bronsted-Lowry acid or as a Bronsted-Lowry base. Write equations to show both of these reactions with water
I need help answering these 3 questions
Discuss healthy water intake and output levels to maintain water balance. Be able to list safety concerns about our water supply. Classify the minerals as major or trace minerals, and be able to list conditions of the body, dietary factors, and other pertinent relationships that influence the absorption, retention, and availability of specific minerals.
1. How would you prepare a liter of "carbonate buffer" at a pH of 10.07? You are provided with carbonic acid (H2CO3), sodium hydrogen carbonate (NaHCO3), and sodium carbonate (Na2CO3). Please give an explanation. 2. Provide the mole ratio to support your answer. (Give your answer in the form base : acid.)
1. How does water dissolve minerals? 2. Under what circumstances cause minerals to precipitate from water?

The human body is composed of water, proteins, fat, and
minerals. Its
specific heat reflects this composition. With 72% water and 28%
protein, calculate the specific heat of the human body.
Substance Specific heat(cal/g°C) 1 Water Ice 0.480 Soil 0.2 to 0.8, depending on water content 0.214 0.4 Aluminum Protein
i need help explaining this,
explain the results. discuss the change in pH for water and
contrast it to the change in pH of the buffer system
thanks

Lab 5 Buffers 1. Dissolved ions in salt solutions can act as acids or bases and react with water to produce hydronium ions or hydroxide ions that contribute to the pH of the salt solution. Since strong acids and strong bases completely ionize in solution, the reverse reaction essentially does not occur, meaning that the resulting conjugate base of a strong acid or conjugate acid of a strong base do NOT act as acids or bases. Ions that are conjugate...

Describe how to make 2.0L of a 2.00 M solution of sodium carbonate from solid sodium carbonate(s). b. Describe how you can make a buffer with sodium carbonate(s) by adding hydrochloric acid. c. How many mL of 1.00 M HCl(aq) are needed to be added to 10.00 g of sodium carbonate to make a buffer at pH =10.00. Ka of HCO3- is 4.7 x 10-11.
