Tpy6a [65]

Answer:

The equilibrium constant in terms of concentration that is, $K_c=3.6243\times 10^{3}$ .

Explanation:

$PCl_3(g)+Cl_2(g)\rightleftharpoons PCl_5(g)$

The relation of $K_c\& K_p$ is given by:

$K_p=K_c(RT)^{\Delta n_g}$

$K_p$ = Equilibrium constant in terms of partial pressure.=98.1

$K_c$ = Equilibrium constant in terms of concentration =?

T = temperature at which the equilibrium reaction is taking place.

R = universal gas constant

$\Delta n_g$ = Difference between gaseous moles on product side and reactant side= $n_{g,p}-n_{g.r}=1-2=-1$

$98.1=K_c(RT)^{-1}$

$98.1 =\frac{K_c}{RT}$

$K_c=98.1\times 0.0821 L atm/mol K\times 450 K=3,624.30=3.6243\times 10^{3}$

The equilibrium constant in terms of concentration that is, $K_c=3.6243\times 10^{3}$ .

The anticodons corresponding to the codons on the mRNA (from part A) is 5' CGA - AAA - GUU 3'.

<h3>What are anticodons?</h3>

Anticodons are nucleotide sequences on tRNA molecules that are complementary to the codons found on mRNA molecules.

The anticodons on tRNA molecules determine the amino acid that is carried by the tRNA.

Just like codons, anticodons occur in triplets of nucleotide sequences.

Considering the codons on the mRNA molecule:

3’ GCT | TTT | CAA | AAA ’5

The complementary anticodon will be:

5' CGA - AAA - GUU 3'

You are given 3.0 grams of solid sodium to react to pure water which has a molarity of 55.6 M. How many milligrams of H2 can be

serious [3.7K]

Answer:

= 15.51 mL

Explanation:

Here's is the reaction:

2HgO(s) ⇒ 2 Hg(s)+O₂(g)

In this reaction 2mol HgO = 1mol O₂

The molecular weight of HgO = 216.59g

so, 3.0g HgO = 3.0g x 1.00molHgO/216.59gHgO

= 0.0138511 molHgO

The amount of Oxygen follows:

0.0138511 molHgOx1/2= 0.00692555 mol O₂

Now, volume of 1 any gas = 22400mL

so, 0.00692555 mol O₂ x22400mLO₂/1mol O₂

= 15.513232mL O₂

Student conducts an experiment to determine the enthalpy of solution for lithium chloride dissolved in water. the student combin

nirvana33 [79]

Answer:- $\Delta H_s_o_l_n=-37.2\frac{kJ}{mol}$

Solution:- First of all we calculate the heat absorbed or released when the solute is added to the solvent. Here the solute is LiCl and the solvent is water.

To calculate the heat absorbed or released we use the formula:

$q=ms\Delta T$

q = heat absorbed or released

m = mass of solution

s = specific heat capacity

and $\Delta T$ = change in temperature

mass of solution = mass of solute + mass of solvent

mass of solution = 5.00 g + 100.0 g = 105.0 g

(note:- density of pure water is 1 g per mL so the mass is same as its volume)

$\Delta T$ = 33.0 - 23.0 = 10.0 degree C

s = $4.18\frac{J}{g.^0C}$

Let's plug in the values in the formula and calculate q.

q = $105.0g(4.18\frac{J}{g.^0C})(10.0^0C)$

q = 4389 J

To calculate the enthalpy of solution that is $\Delta H_s_o_l_n$ we convert q to kJ and divide by the moles of solute.

moles of solute = $5.00g(\frac{1mol}{42.39g})$

= 0.118 moles

q = $4389J(\frac{1kJ}{1000J})$ = 4.389 kJ

$\Delta H_s_o_l_n=\frac{4.389kJ}{0.118mol}$

$\Delta H_s_o_l_n$ = $37.2\frac{kJ}{mol}$

Since the heat is released which is also clear from the rise in temperature of the solution, the sign of enthapy of solution will be negative.

So, $\Delta H_s_o_l_n=-37.2\frac{kJ}{mol}$
