Answer:
50 g Sucrose
Explanation:
Step 1: Given data
- Concentration of the solution: 2.5%
Step 2: Calculate the mass of sucrose needed to prepare the solution
The concentration of the solution is 2.5%, that is, there are 2.5 g of sucrose (solute) every 100 g of solution. The mass of sucrose needed to prepare 2000 g of solution is:
2000 g Solution × 2.5 g Sucrose/100 g Solution = 50 g Sucrose
Answer:
<h2>The carboxyl group of one amino acid that is X and the amino group of other amino acid that is Y.</h2>
Explanation:
The amino acid is such type of the organic compound that contains one central carbon atoms and four other groups are directly connected with central carbon atoms such as one hydrogen atom, one R group, one carboxyl group, and one amino group.
The carboxyl group and amino group plays an important role in the formation of the peptide bond. When the formation of a peptide bond, takes place then two amino acids are involved in which the carboxyl group of one amino acid and the amino group of other amino acids are linked to form a peptide bond.
Answer:
C
Explanation:
It afffects changes in pressure and temperature not melting and boiling points
Answer:
B) Either speed or direction can change
There are only two ways for you to accelerate: change your speed or change your direction—or change both. If you're not changing your speed and you're not changing your direction, then you simply cannot be accelerating—no matter how fast you're going.
Answer:
The ion will repel the substance because it has lost two electrons.
Explanation:
An ion is a charged specie. We can see from the question that the ion has twelve positive and ten negative particles.
If there are more positive particles than negative particles, then the ion is positively charged.
If the ion is positively charged, it will repel another positively charged particle because like charges repel while opposite charges attract.
