If you increase the solute amount but keep the solution volume the same what
solmaris [256]

Answer: Molarity increases

Explanation:

Molarity, also known as concentration in moles/dm3 or g/dm3, is calculated by dividing the amount of solute dissolved by the volume of solvent. So, Molarity (c) = amount of solute (n) / volume (v)

i.e c = n/v

Hence, molarity is directly proportional to the amount of solute dissolved, and inversely proportional to the volume of solvent.

Thus, at same volume, any increase in solute amount increases molarity while a decrease will also decreases molarity.

Suppose an object is moving through space in a straight line. What could cause the object to start moving in a circle?
MAVERICK [17]
It could pass by a large enough object that has enough gravity to pull the object into its orbit and the object would stay in orbit because it has centripetal force.

which bonds maintain the primary structure of a protein? question 7 options: ionic bonds hydrogen bonds peptide bonds disulfide
Mariulka [41]

Proteins have four structures primary, secondary,m tertiary, and quaternary. The primary structure of the protein has been known to have peptide bonds. Thus, option C is correct.

<h3>What are peptide bonds?</h3>

Peptide bonds are the chemical bonds that are involved in protein polymer formation by linking the amino acid chains. They are also called amide bonds that are present between the nitrogen and the carbonyl atom.

The primary structure of the proteins includes the amino linked by the peptide bonds that make them look like linear structures. The secondary structures have hydrogen bonds and the tertiary have ionic and hydrophilic hydrogen bonds.

Therefore, option C. the primary structure of the protein contains peptide bonds.

What is the mass of hydrogen in 5.5 mol of Ca(OH)2?​
Morgarella [4.7K]

Answer:

12*2*6.022*10^23. Atoms of hydrogen.

Explanation:

First of all if u know that 1 molecule of calcium hydroxide contain 2 hydrogen atom and 1 mole of calcium hydroxide contain 6.022*10^23 molecules of calcium hydroxide.

Hence 1 mole of calcium hydroxide contain 2*6.022*10^23 atom of hydrogen.

So 12 mole of calcium hydroxide contain =12*2*6.022*10^23. Atoms of hydrogen.
