How many times larger is the number of Hydrogen atoms than Oxygen atoms in a disaccharide?
WARRIOR [948]

There are twice the number of Hydrogen atoms than Oxygen atoms in a disaccharide.

<h3>Disaccharides</h3>
  • Disaccharides are carbohydrate compounds containing two monosaccharide units linked together by glycosidic bonds

Examples of disaccharides include sucrose and maltose.

  • The ratio of hydrogen to oxygen atoms in a carbohydrate is always a 2:1.

For example, the formula of sucrose is C₁₂H₂₂O₁₁

> The ratio of hydrogen to oxygen atoms is 2;1

Therefore, there are twice the number of Hydrogen atoms than Oxygen atoms in a disaccharide.

List 3 possible futures for the universe
Marina86 [1]

1 possible future is The Big Crunch. This theory assumes that the average density of the universe will be enough to stop its expansion and begin contracting.

2. Some theorists state that the expansion of the universe will go on forever, and if that happens, the universe will cool as it expands, and then it will become too cool to sustain life.

3. The Big Rip. The universe may keep expanding, as I mentioned before. But as it expands, the gravity may not be able to hold all the planets together, as it is now. Galaxies would tear apart first, followed by smaller black holes, planets and stars. Eventually, space would start expanding faster than the speed of light, and atoms would start breaking down into super small particles and everything would fall into nothing.

Kathy was making liquid growth medium for plants. The pH of the original solution was 8. The optimal pH for plant growth is 6. W
liubo4ka [24]

If referring to the question: Kathy was making liquid growth medium for plants. The pH of the original solution was 8. The optimal pH for plant growth is 6. What was the best compound to add to make it pH=6?

A) KOH

B) HCL

C) Water

D) No answer provided

Then the correct answer would be option B, to add HCL, known as Hydrochloric acid to lower the pH to 6.

In science, pH is a scale used to measure the acidity of a solution or its basicity. The scale ranges from 0 to 14. A pH of 7 would mean that the given solution is neutral, lower than 7 equates to an acidic solution, while anything above 7 becomes increasingly basic.

Option A is to add KOH, or potassium hydroxide to the original solution whose starting pH is 8. KOH is a solution whose pH is above 8,  a strong base, and is often used to increase the pH of a solution. In the question it states what the desired pH is 6, therefore we want to lower, not increase the pH. This makes option A incorrect.

Water is a neutral solution. Even though it is neutral, it is not used to neutralize basic or acidic solutions. Acid or bases may be added to water to create very diluted solutions that are nearly neutral despite containing a strong base or acid, but this is a different process than neutralization and will not give the desired pH. Option C is also wrong.

Option B is correct because HCL, known as hydrochloric acid is a strong acid, commonly used to lower the pH of a solution by increasing the concentration of hydrogen ions. Since we start with a pH of 8 and wish to achieve a pH of 6, HCL is the correct component to add to the solution. Due to option B being correct, option D that states that no answer is provided, is incorrect.
