Answer:
1:1 ratio
Water (H2O) splits into Hydrogen Ions (H+) and Hydroxyl Ions (OH-). When there are equal parts of Hydrogen Ions (H+) and Hydroxyl Ions (OH-) leading to a 1:1 ratio, pH is neutral (7).Explanation:
The concentration of H + ions at pH 6. The concentration of H + can be deduced by the formula pH = - log H + ==> H + = 10 ^ (- pH) ...
Concentration of -OH at pH 6. The concentration of -OH can be calculated from pOH: pOH = 14 - pH = 14 - 6 = 8. ...
Calculation of the ratio H + / -OH:
Nitrogen has five valence electrons. For this reason, it often bonds to gain three electrons. Based on the arrangement of the elements in the periodic table, which other element most likely shows similar behavior ?

Describe the relationship between the three processes important to sedimentary rock formation: deposition, compaction and cementation.
and
How do you think the formation of fossils in sedimentary rock disrupts or alters the process of sedimentary rock formation? In other words, how does the formation of a fossil fit into the process of sedimentary rock formation? Defend your answer.
Answer:
I can't help sorry
Explanation:
Answer:
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.

1. write a sentence that describes how the food changes in the stomach.
2. write a sentence that describes how the food changes in the small intestine.
3. explain what happens to digested food in the small intestine
4. write a sentence that describes what happens to digested food in the cell.
Answer:1.Once filled with food, the stomach grinds and churns the food to break it down into small particles. It then pushes the small particles of food into the first part of the small intestine, called the duodenum. The small intestine is where most of the digestion and absorption of our food takes place.2.The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.3.The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.4.The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.
