The reaction of nitrogen monoxide and its rate law are shown below. The concentration of NO is 0.025 M, and the concentration of

H2 is 0.075 M.
2NO(g)+2H2(g) -------> N2(g)+2H2O(g)

At a given temperature, the rate constant is 1.2 M-2 x s-1. What is the rate at this temperature for the given concentrations?

There are no multiple choice options. It's just (blank) M x s-1

What can you say about the strength of the intermolecular forces in neon and argon based on the critical points of Ne and Ar? (c
algol13

Explanation:

Since, it is given that critical temperature of Argon is 150.9 K and critical pressure of Argon is 48.0 atm.

It is known that gas phase of neon occurs at 50 K. As the boiling point of Ar is more than the boiling point of neon which means that there is strong intermolecular force of attraction between argon molecules as compared to neon molecules.

This is also because argon is larger in size. As a result, induced dipole-induced dipole forces leads to more strength in Ar as compared to Ne.

Wich tools are appropriate to determine the densety of an irregular-shaped object ?
Svetach [21]

Answer:

The most accurate way to determine an object's volume, especially in the case of an irregularly shaped object, is to immerse it in water and measure the amount of water it displaces. A graduated cylinder large enough to hold both the object and enough water to fully immerse it is the best tool for this job.

An atom with which atomic diagram is most similar to calcium?
Dominik [7]

Answer:

C

Explanation:

Calcium is an element with a total of 20 electrons.

 It has 4 shells with a configuration of:

          2, 8, 8, 2

Option C is the most similar to calcium but the number of shells is not complete.

It still requires two more shells with 8 and two electrons respectively.

Identify ALL the possible mol ratio from<br> this balanced equation:
grandymaker [24]

Answer:

\frac{1 mole of N_{2} }{3 moles of H_{2} }

Explanation:

The equation of the reaction:

   Nitrogen gas N₂ reacts with Hydrogen as H₂ to produce ammonia NH₃;

 

          N₂    +    H₂    →    NH₃  

 The balanced equation is ;

        N₂    +    3H₂    →    2NH₃  

The mole ratio is the ratio of the coefficients of the combining reactants;

   1 mole of N₂ combines with 3 mole of H₂;

So;

      \frac{1 mole of N_{2} }{3 moles of H_{2} }
