Answer : The balanced chemical reaction will be,
![ZnS+2HBr\rightarrow ZnBr_2+H_2S](https://tex.z-dn.net/?f=ZnS%2B2HBr%5Crightarrow%20ZnBr_2%2BH_2S)
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.
The coefficient tell us about that how many molecules or atoms present in the chemical equation.
The given chemical reaction is,
![ZnS+HBr\rightarrow ZnBr_2+H_2S](https://tex.z-dn.net/?f=ZnS%2BHBr%5Crightarrow%20ZnBr_2%2BH_2S)
This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen bromine atoms are not balanced.
In order to balance the chemical equation, the coefficient '2' put before the
and we get the balanced chemical equation.
The balanced chemical reaction will be,
![ZnS+2HBr\rightarrow ZnBr_2+H_2S](https://tex.z-dn.net/?f=ZnS%2B2HBr%5Crightarrow%20ZnBr_2%2BH_2S)
Answer:

I am pretty sure you can't, but hey everything is possible! :)
Answer:
3.45 moles Li contains 2.08
×
10
(to the power of)24 atoms
.
Explanation:
The relationship between atoms and moles is:
1 mole atoms
=
6.022
×
10
(to the power of)23
atoms
In order to determine how many atoms occupy a given number of moles, multiply the given moles by
6.022
×
10
(to the power of)23
atoms/mole
.
In the case of 3.45 moles lithium (Li):
3.45
mol Li
×
6.022

10
(to the power of)23 atoms Li/
1
mol Li
=
2.08

10
(to the power of)24
atoms Li rounded to three
There are 4 atoms of sodium in the formula of sodium sulfite.
<h3 /><h3>Number of atoms at sodium</h3>
There are 4 atoms of sodium in the formula of sodium sulfite because 4 digit is placed before sodium which shows the number of sodium atom present in the molecule while on the other hand, 2 is placed in front of sulfur which tells us that 2 atoms of sulfur is used in the making of sodium sulfite.
<h3>Reasons of war</h3>
In this excerpt, Paine is attempting to convince the readers that we have righteous reasons to justify supporting the war. We should participate and take part in the war in order to defend ourselves and our country but avoid offensive war to gain financial benefits.
