Answer:
U gotta check ur book for that or Google maybe..
An acid is a substance that dissociates in water to produce hydrogen ions or protons.
<u>Answer:</u> The number of atoms of bromine present in given number of mass is 
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of bromine = 1.37 g
Molar mass of bromine = 79.904 g/mol
Putting values in above equation, we get:
According to mole concept:
1 mole of an element contains 
number of atoms.
So, 0.0171 moles of bromine will contain = 
number of bromine atoms.
Hence, the number of atoms of bromine present in given number of mass is
Answer:
187 moles NH₃
Explanation:
To find the amount of ammonia formed, you need to multiply the given value by the mole-to-mole ratio consisting of both relevant molecules. The mole-to-mole ratio is made up of the molecules' coefficients in the balanced equation. The desired unit should be placed in the numerator of the ratio. The final answer should have 3 sig figs to reflect the lowest amount of sig figs among the given values.
1 N₂ + 3 H₂ ----> 2 NH₃

93.5 moles N₂ 2 moles NH₃
---------------------- x ------------------------- = 187 moles NH₃
