Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid. what is the molar concentration of [h3o+] in a cola that has a ph of 3.120? (for with significant figures, see hint 3.) view available hint(s) what is the molar concentration of [h3o+] in a cola that has a ph of 3.120? (for with significant figures, see hint 3.) 7.58 × 10−4 7.59 × 10−4 7.6 × 10−4 3.120 × 10−3 0.494 1.318 × 103

Answer;

= 7.59 × 10^-4 M

Explanation;

The molar concentration of [H3O+] in a cola with a pH of 3.120 can be calculated by:

[H3O+]=10−pH

[H3O+]=10−3.120

[H3O+]=7.59×10−4M

Ingestion of large amounts of phosphoric acid found in cola can upset the body's regulation of bone metabolism and reduce the absorption of calcium from the diet. For this reason, people who are at risk of developing osteoporosis are often advised not to drink much cola.

"Select the correct arrows" There is more than one answer.

According to the rock cycle, Igneous to Sedimentary and Metamorphic to Sedimentary are both weathering/erosion.

While Igneous to Metamorphic and Sedimentary to Metamorphic are both heat/pressure.

Also Metamorphic to Igneous and Sedimentary to Igneous are both melting.
