Calculate the ratio of H+ ions to OH– ions at a pH = 6. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide. Then divide the H+ concentration by the OH– concentration. Record this calculated ratio in Table A of your Student Guide.

What is the concentration of H+ ions at a pH = 6? mol/L
What is the concentration of OH– ions at a pH = 6? mol/L
What is the ratio of H+ ions to OH– ions at a pH = 6? :1

Answers

Answer 1

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:

What is the rock’s velocity when it reaches the bottom? How do you know?

Answers

Thus the rock hits the surface after about 5.38 s. Thus the rock hits the surface with a velocity of about -10.01 m/s. If you want to know the velocity of the object at some point before it hits the ground, use the distance the object has fallen at that point in place of the distance to the ground in either equation.

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.

After Michelle went on vacation for two weeks, she came home to find her potted plants had turned brown and died. The soil was very dry. While Michelle was away, she kept the curtains and windows closed and did not have a neighbor come by to water her plants. Michelle now realizes that she will have to do things differently the next time she is away for several days if she wants to keep her plants alive. Why is it important for Michelle to make sure her plants have their needs meet while she is away?

A.
She needs to make sure the plant receives water, sunlight, and air. Plants need all components to make their own food.

B.
She needs to be sure to put plant food in the pot. Plants need to be feed because they do not make their own food.

Answer:

A.water is a molecule

Explanation:

water is a molecule not a element

Answer: A. It is an element.

Explanation: An element cannot be broken down into simpler substances. For example, oxygen and hydrogen are elements.
A compound is two or more elements joined by electrons. Water is a compound.
The formula for water is H2O, which can be read as “two hydrogen atoms and one oxygen atoms.” Therefore, water contains both oxygen and hydrogen.

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.

Answers

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.
