The answer to this item depends entirely to the chemical reaction. If the compound, NH4Cl, is in the left hand side of the reaction, when it is added, the reaction will shift to the left. In the same manner, when the compound is in the right-hand side of the reaction, the reaction will shift to the right.
This happens because initially the reaction is in equilibrium and adding another compound to it will most likely lead to the shifting of the reaction.
Question∵
Compared to visible light, an electromagnetic wave that has a longer wavelength will also have?
Answer:
Hi, There! -Randp12- My Name Is jay I'm here to help! :)
<u><em>The correct answer is lower frequency.</em></u>
Explanation:
Information to Support My Answer :D
it is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa.
Therefore for higher wavelength, the electromagnetic wave will also have lower frequency.
Hope this helps!

Two [hydrogen] atoms and one [oxygen] atom
Answer: A. Energy was absorbed
Answer:
Mass of NaOH required= 60 g
Explanation:
Given data:
Mass of NaHCO₃ = 126 g
Mass of NaOH required = ?
Solution:
Chemical equation:
NaOH + CO₂ → NaHCO₃
Number of moles of NaHCO₃:
Number of moles = mass/ molar mass
Number of moles = 126 g/ 84 g/mol
Number of moles = 1.5 mol
Now we will compare the moles of NaHCO₃ and NaOH.
NaHCO₃ : NaOH
1 : 1
1.5 : 1.5
Mass of sodium hydroxide:
Mass = number of moles × molar mass
Mass = 1.5 mol × 40 g/mol
Mass = 60 g
