9.98 g of NH₃ reacts with 23.4 g of O₂ (up to 3 significant figure).

<h3>What is Significant figures ?</h3>

The digits of a number that are used to express it to the required degree of accuracy, starting from the first non-zero digit.

The given chemical equation ;

4NH₃ + 5O₂ ---> 4NO + 6H₂O

Therefore,

4 moles of NH₃ reacts with 5 moles of O₂.

i.e,

68 g of NH₃ reacts with 160g of O₂.

Therefore,

9.98 g of NH₃ reacts with :

      = 160/68 x 9.98

      = 23.4 g of O₂ (up to 3 significant figure)

Why atoms in our body don’t <br><br>eject electrons?​
Zolol [24]

Answer:

When there are too many protons, some of the outer protons are loosely bound and more free to react with the electron. But most atoms do not have too many protons, so there is nothing for the electron to interact with. As a result, each electron in a stable atom remains in its spread-out wavefunction shape.

In an atom, there is a nucleus made up of neutral charged, neutrons, and positively charged protons. The reason why electrons which are negatively charged, don't fly off is due to its stronger attraction to the protons. ... This, however, still allows the electrons to move around the nucleus of an atom.

How many moles of N2 are needed to make 5.0 moles of NH3?
Juli2301 [7.4K]

Answer:

The answer is "2.5 mole"

Explanation:

The reaction for producing NH_3 can be defined as follows:

Reaction:

N_2+ 3H_2 \rightarrow 2NH_3

According to the above reaction, to produce 2 moles of NH_3  we need 1 mole of nitrogen:

So, according to the question to produce 5.0 mole NH_3 the required N_2:

\Rightarrow \ 5.0 \ mole \ of \ NH_3  \times  \frac{1 \ mole\ of \ N_2}{2 \ mole \ of NH_3}\\\\\Rightarrow 5.0 \times \frac{1}{2}\\\\\Rightarrow 2.5\  mole\\

To produce 5.0 mole NH_3  we need 2.5 mole N_2

Which of the following could be the rate equation for a first order reaction? please help this is timed
wel

Rate = k[A] = first order reaction

<h3>Further explanation</h3>

Given

Rate law

Required

A first-order reaction

Solution

The rate law : equation for the rate of chemical reaction

For reaction

aA + bB ⇒ C

The rate : r = k[A]ᵃ[B]ᵇ

The sum of exponents(a+b) is the reaction order

From the choice :

a. a+b = 2, second order reaction

b. a+b = 3, third order reaction

c. a+b = 4, fourth order reaction

d a+0 = 1, first order reaction
