How many amino acids can compose a protein molecule?

Word equations- Please help ASAP

nekit [7.7K]

Answer:

See answer below

Explanation:

In this case, you just need to use any acid you want (Like HCl, or H₂SO₄) to do this exercise.

You are given a sample of what you have to do which is:

Acid + metal ------> Salt + hydrogen

As you can see, an acid like the ones I wrote above, have hydrogen atoms, so you should put the hydrogen there. As for the part of salt, you just need to draw the corresponding salt that is formed when the acid reacts with the metal, and write it's name.

Let's do all three equations for you to a better understanding. For all the given examples, I will use HCl as acid, and i will explain one reaction cause the other two reactions happens the same thing, only with a different metal.

1. 2HCl + Zn ------> ZnCl₂ + H₂

As you can see, we just have a displacement reaction where the metal displaces the position of the hydrogen to form the salt and the hydrogen leaves the molecule as a gaseous molecule. Written in words it would be:

Hydrochloric acid + Zinc ----> Zinc chloride + hydrogen

2. 2HCl + Pb -------> PbCl₂ + H₂

Hydrochloric acid + lead ------> Lead (II) chloride + hydrogen

3. 2HCl + Fe -------> FeCl₂ + H₂

Hydrochloric acid + iron ------> Iron (II) chloride + hydrogen

Hope this helps

Name the types of polymerization and the differences

Talja [164]

Condensation polymerization : releasing water as by product, occurs in monomer that has functional group that can react with each other e.g alcohol&carboxlic acid to form polyesters, carboxylic acid and amines to form polyamides,etc.

Radical Polymerization: occurs by propagating radical monomers or monomer that has unsaturated bonds, such as ethene, initiated by formation of radical from the monomer by using uv lights/other initiator, does not produce any by products

Which is the correct equilibrium constant expression for the following reaction? Fe2O3(s) + 3H2(g) --> 2Fe(s) + 3H2O(g) Kc =

svetlana [45]

Answer:

The equilibrium constant Kc = [Fe]²*[H2O]³ / [Fe2O3][H2]³

Explanation:

Step 1: Data given

For the reaction aA + bB ⇆ cC + dD

the equilibrium constant Kc = [C]^c * [D]^d/[B]^b*[A]^a

Step 2: The balanced equation

Fe2O3(s) + 3H2(g) --> 2Fe(s) + 3H2O(g)

Step 3: Calculate the equilibrium constant Kc

Kc = [C]^c * [D]^d/[B]^b*[A]^a

⇒with [C] = [Fe]

⇒ with c = 2

⇒with [D] = [H2O]

⇒with d = 3

⇒with [A] = [Fe2O3]

⇒with a = 1

⇒with [B] = [H2]

⇒with b = 3

Kc = [C]^c * [D]^d/[B]^b*[A]^a

Kc = [Fe]²*[H2O]³ / [Fe2O3][H2]³

The equilibrium constant Kc = [Fe]²*[H2O]³ / [Fe2O3][H2]³

List the three principal states of matter, give two examples of each

icang [17]

matter can take be one of the three states which are; (Solid, Liquid, Gas)

Think about water, it can be a Solid (Ice) a Liquid (not frozen obviously) and a Gas (when it evaporates)
