ELEN [110]3 years ago
8 0

Answer:

Rate = K[NH₄⁺][NO₂⁻]

Explanation:

In kinetics studies of reaction, rate law is a mathematical expression that relates speed of reaction with concentrations of the reactants. For a reaction:

aA + nN → cC + dD

The rate law is expressed in terms of [A] and [B] as follows:

Rate = K[A]ᵃ[N]ⁿ

<em>Where K is rate constant.</em>

<em />

For the reaction:

NH4+ + NO2– ⟶ N2 + 2H2O

The rate law is:

<h3>Rate = K[NH₄⁺][NO₂⁻]</h3><h3 />

<em>As was said in the problem, the rate is porportional to [NH₄⁺] and to [NO₂⁻]</em>

A 4.24 kg marble slab has the volume of 1564 cm3 What is the density in g/cm3
miskamm [114]

Answer:

The answer is

<h2>2.71 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

volume of marble = 1564 cm³

1 kg = 1000 g

4.24 kg = 4240 g

mass = 4240 g

The density is

density =  \frac{4240}{1564}   \\  = 2.710997442...

We have the final answer as

<h3>2.71 g/cm³</h3>

Hope this helps you

What does this equation, 2 C(s) + O 2(g) ® 2 CO(g), tell us?
Zanzabum

Answer:

D. All of these.

Explanation:

For an equation to be balanced the number of atoms of each kind in the reactants and the products should be the same.

Then from this equation, CO  is a product.

Last, two carbon atoms undergo reaction with the oxygen molecule for complete reaction to occur. Each atom combines with one oxygen atom.

A balanced chemical equation is shown below
IrinaVladis [17]

Answer:

The answer is A.

Explanation:

C6H12O6 + 6O2 -> 6CO2 + 6H20

C6H12O6 + 6O2 -> 6CO2 + 6H20At the reactant side, there are 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms.

atoms, 12 hydrogen atoms and 18 oxygen atoms.At product side, there are 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms.

(In a balanced equation, the no. of atoms on the reactant side must be <em><u>e</u></em><em><u>q</u></em><em><u>u</u></em><em><u>a</u></em><em><u>l</u></em><em> </em>to the no. of atoms on the product side)
