Which element is more likely to dissociate into its monatomic form at 3000 K. H or N. Why?

Chemistry

Oliga [24]2 years ago

Answer:

H2

Explanation:

In the first place it is necessary to consider that these two elements will be their diatomic form initially, that is, H2 and N2.

first we should check the equilibrium constant Kp tables in this case at a temperature of 3000K

Value for dissociation reaction of H2  in Kp = -3.685

Value for dissociation reaction of N2 in Kp = -22.359

Equilibrium constant for H2 dissociation is higher than N2 dissociation. so for this comparation H2 is more likely to dissociate.

Under identical conditions of temperature and pressure, which of the following gasses is the densest: Ne, CO2, or Cl2?
Tanzania [10]
Cl2=3.17g/L
Ne=.901g/L
CO2=1.96g/l
 therefore Cl2 is the densest gas under the given conditions.

Evaluate the following conversion. Will the answer be correct? Explain. If incorrect, how could you adjust one of the factors to
elena55 [62]

Given :

Rate = 75 m 1 s×60 s 1 min×1 h 60 m.

To Find :

Correct answer after conversion.

Solution :

We know, 1 min = 60 sec.

1 hour = 60 min = 60×60 sec = 3600 sec.

Putting value of min and hour in seconds , we get :

R=((75\times 60) + 1 )\times ( (60 + 1)\times 60 ) \times ( 3600+3600)\ s^3\\\\R=1.186\times 10^{11} \ s^3

Hence, this is the required solution.

There are two types of nucleic acids, dna and rna. nearly all organisms use dna, not rna, as the central repository for genetic
Leya [2.2K]
Found the choices. Pls see attachment. 

The statements that explains this phenomenon are:
1) DNA contains adenine as one of its nitrogenous bases.
2) DNA has a double-stranded structure that ensures an accurate mechanism of duplication.

How many moles of KCl will be<br> produced from 15.0 g of KClO3?
slega [8]

Answer:

0.12 mol KCl

Explanation:

2 KClO3 (s)   2 KCl (s) + 3 O2 (g)

15 g                x mol

x g KCl = 15 g KClO3 x[ (1 mol KClO3)/ (122.5 g KClO3) ] x [(2 mol KCl)/ (2 mol KClO3)]

x g KCl = 0.12 mol KCl

How many lead (Pb) atoms will be generated when 5.38 moles of ammonia react according to the following equation: 3PbO+2NH3→3Pb+N
jasenka [17]

Answer:

4.86×10^23 molecule of Pb

Explanation:

Based on that equation, for every 2 moles of ammonia, you get 3 moles of lead.

So:

2 mol NH3/ 3 mol Pb

Using this ratio we can find the amounts of either molecule. Given 5.38 mol NH3:

(5.38 NH3)(3 Pb/ 2 NH3) = (5.38)(3/2) mol Pb = 8.07 mol Pb

Then, we just need to use Avagadro's number to get the number of molecules.

(8.07)(6.02×10^23) = 4.86×10^23 molecule of Pb
