maks197457 [2]3 years ago
5 0

Option 4 is right option regarding incorrect association.

A nucleotide is a monomer made of sugar, base and phosphate group whereas nucleic acid is a polymer of nucleotide. Thus, this association is correct.

Amino acid is a monomer such as glycine, alanine whereas polypeptide made from association of number of amino acid by creating a peptide linkage to produce a polypeptide.

Monosaccharide is a monomer such as glucose, fructose which associates together to produce polysaccharide such as cellulose made from glucose.

nucleic acid is a polymer of nucleotide whereas polypeptide made from association of number of amino acid by creating a peptide linkage to produce a polypeptide.

Thus, option 4 is right option having incorrect association.

if a standard die is rolled twice what is the probability of getting a perfect square,then a number that is less than 5.
solniwko [45]
There are three perfect squares in a standard die; 1, 2, 4. If there is two standard dies, then the probability of getting a perfect square is 1/3 x 1/3 = 1/9. 
There are 4 numbers less than 5 in a standard die, making it 1/4 x 1/4=1/16.

Which is the most active nonmetallic element in group 16?
timama [110]
Oxygen

For metals, reactivity increases as we move through the elements in the period table from top to bottom, and left to right. In contrast, for nonmetals, reactivity increases as we move through the elements in the periodic table, as we move from bottom to the top, and right to left. 

Group 16 on the periodic table is also called the oxygen family or chalcogens. It includes the following elements from top to bottom: Oxygen, Sulfur, Selenium, Tellurium, and Polonium. Of these, only Oxygen, Sulfur, and Selenium are nonmetals. Since reactivity of nonmetals increases going up the periodic table, oxygen is therefore the most reactive nonmetal in the group. Shown in the figure below is the reactivity trend in the periodic table.

Answer:

NH₃

M = n/V(L)

0.844 mol (Both numbers have 3 significant figures so the result has 3 significant figures as well)

Explanation:

Step 1: Given and required data

  • Volume of solution (V): 375. mL
  • Molar concentration of the solution (M): 2.25 M
  • Chemical formula for ammonia: NH₃

Step 2: Calculate the moles (n) of ammonia (solute)

Molarity is equal to the moles of solute divided by the liters of solution.

M = n/V(L)

n = M × V(L)

n = 2.25 mol/L × 0.375 L = 0.844 mol (Both numbers have 3 significant figures so the result has 3 significant figures as well)

How does the city filter our drinking water?
pantera1 [17]
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is disinfected for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including fulfilling the requirements of medical, pharmacological, chemical and industrial applications. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination  and the use of electromagnetic radiation such as ultra violet light.
