Answer:

C. The mass of an electron is much less than the mass of a proton or

a neutron.

Explanation:

When we compare the mass of an electron to that of proton or neutron, the mass of an electron is much less than the mass of a proton or a neutron.

Electrons are negatively charged particles in an atom

Protons are positively charged particles

Neutrons do not carry any charges.

  • The relative mass of an electron compared to that of a proton is \frac{1}{1840}
  • This is a very small value
  • Electrons generally have mass of 9.11 x 10⁻³¹kg
  • Protons weigh 1.67 x 10⁻²⁷kg
  • Neutrons weigh  1.68 x 10⁻²⁷kg

We can see that electrons have very small mass and this is why when calculating the mass of an atom, we use the sum of the number of protons and neutrons.

How many silver atoms are there in 3.78g of silver?
oksian1 [2.3K]

2.1 x 10²²atoms

Explanation:

Given parameters:

Mass of silver = 3.78g

Unknown:

Number of atoms of silver = ?

Solution:

To solve this problem, we first find the number of moles of the silver from the given mass.

  Number of moles = \frac{Mass}{Molar mass}

Molar mass of Ag  = 108g/mole

   Number of moles = \frac{3.78}{108}  = 0.035mole

Now;

  A mole of any substance contains 6.02 x 10²³ atoms

     0.035 moles of Ag will contain 0.035 x 6.02 x 10²³ = 2.1 x 10²²atoms

Chemical reactions that combine simple molecules and monomers to form complex structures are known as
jolli1 [7]

Answer: Anabolism

Explanation:

Chemical reactions that combine simple molecules and monomers to form complex structures are known as ANABOLISM.

Anabolic reactions which are also called biosynthesis reaction is a type of metabolic reaction in the body that forms larger molecules through combination of smaller molecules with the use of energy in the form of ATP molecules. Example if anabolic reactions in the body includes:

- formation of polysaccharide from monosaccharides,

- formation of triglycerides from fatty acids,

- formation of nucleic acids from nucleotides and many among others. I hope this helps, thanks.
