Answer:

intermolecular attractive forces hold the molecules in contact, although they still have sufficient KE to move past each other. Intermolecular attractive forces, collectively referred to as van der Waals forces, are responsible for the behavior of liquids and solids and are electrostatic in nature.

I hope this helps!!!!!

Answer:

They allow particles to stay close together.

The attractive forces (bonds) in a liquid are strong enough to keep the particles close together, but weak enough to let them move around each other. For example, Liquids are useful in car brake systems because they flow and cannot be compressed.

Many computer chips are manufactured from silicon, which occurs in nature as SiO2. When SiO2 is heated to melting, it reacts wit

Feliz [49]

Answer:

Theoretical yield for Si = 2586.55*28.09= 72.7 Kg

Percentage yield is =2356.71/2586.55=91.11%

Explanation:

So the chemical equation for this reaction would be SiO2 + 2C = Si + CO

so n(SiO2)=m(SiO2)/M(SiO2)=155400/60.08=2586.55 mol

n(C)=m(C)/M(C)=77400/12.01=6444.63 mol

So Carbon is in exes.

n(Si)=m(Si)/M(Si)=66200/28.09= 2356.71 mol

Theoretical yield for Si = 2586.55*28.09= 72.7 Kg

Percentage yield is =2356.71/2586.55=91.11%

One of the major classes of antibody molecules is immunoglobulin G (IgG). Two heavy chains and two light chains form one IgG mol

olga nikolaevna [1]

Answer:

IgG, IgM, IgA, IgD and IgE

Explanation:

Classes of immunoglobulins

The five primary classes of immunoglobulins are IgG, IgM, IgA, IgD and IgE. These are distinguished by the type of heavy chain found in the molecule. IgG molecules have heavy chains known as gamma-chains; IgMs have mu-chains; IgAs have alpha-chains; IgEs have epsilon-chains; and IgDs have delta-chains.

Differences in heavy chain polypeptides allow these immunoglobulins to function in different types of immune responses and at particular stages of the immune response. The polypeptide protein sequences responsible for these differences are found primarily in the Fc fragment. While there are five different types of heavy chains, there are only two main types of light chains: kappa (κ) and lambda (λ).

Antibody classes differ in valency as a result of different numbers of Y-like units (monomers) that join to form the complete protein. For example, in humans, functioning IgM antibodies have five Y-shaped units (pentamer) containing a total of 10 light chains, 10 heavy chains and 10 antigen-binding.
