What would be the predominant state of matter if there were no intermolecular forces?

Chemistry

loris [4]3 years ago

<span>Stronger Intermolecular forces (greater attractions) hold molecules together better. Meaning the molecules don't want to leave whatever liquid they are part of. for example, chloroform(the knock out gas), which has only weak intermolecular forces evaporates very quickly at room temp. However, water which participates in H-bonding, strong intermolecular forces, evaporates slowly at room temp. The colder a liquid is, the harder it is for the molecules to overcome their intermolecular bonds and break free. a.k.a. slow evaporation. but when a liquid is heated the molecules have enough energy to overcome their brotherly bonds and go into the gas phase.</span>

Given the initial rate data for the reaction A + B –––&gt; C, determine the rate expression for the reaction.
umka21 [38]

Answer:

B) Δ[C]/Δt = 3,60x10⁻² M⁻¹s⁻¹ [A] [B]

Explanation:

For the reaction A + B → C

The formula for rate of reaction is:

Δ[C]/Δt = k [A] [B]

As you have [A], [B] and Δ[C]/Δt information you can multiply [A] times [B] and take this value as X and Δ[C]/Δt as Y. The slope of this lineal regression will be k.

Thus, you must obtain:

y = 3,60x10⁻² X

Thus, rate of reaction is:

B) Δ[C]/Δt = 3,60x10⁻² M⁻¹s⁻¹ [A] [B]

I hope it helps!

Calculate the number of oxygen atoms and its mass in 50g of CaCo3<br>​
xz_007 [3.2K]

The number of oxygen atoms = 3

Mass = 24 g

<h3>Further explanation</h3>

The formula of a compound shows the composition of the constituent elements

CaCO₃ is composed of 3 types of elements, namely Ca, C and O

The amounts of each of these elements in the compound CaCO₃:

  • Ca = 1
  • C = 1
  • O = 3

So the number of oxygen atoms = 3

mass of Oxygen :

\tt mass~O=\dfrac{3\times Ar~O}{MW~CaCO_3}\times mass~CaCO_3\\\\mass~O=\dfrac{3\times 16}{100}\times 50=24~g

Why do you turn a C-terminal aminoacid's carboxyl group into an ester before reducing it to an alcohol? Why not just use LiAlH4
Troyanec [42]

Answer:

Esters are both inorganic and organic acids .... Regarding the second question, it is believed that it is carried out in this way in order to recognize the C-terminal amino acid in a peptide within a protein

Explanation:

The explanation of this question is according to what was interpreted in the question, since it is considered that it is poorly written ...

What happens in this chemical reaction is that it first becomes an ester (organic or inorganic acid) so that it is later recognized in the complex peptide structure.
