I’ll continuously post the answers in the comments, here is the first one:
Na = Metal
CI = Non-Metal
NaCI bond type: Covalent
Hello!
If the frequency of a radio station is 88.1 MHz, the wavelength of the wave used by this radio station for its broadcast is 3.403 m
<h2>Why?</h2>
We are going to use the following equation that shows the relation of the frequency of a wave with its wavelength, knowing that radio waves are electromagnetic waves and they travel at the speed of light (299 792 458 m/s):
Have a nice day!
The first thing you need to do with problem of this kind is to write the chemical equation. This would help you in calculations later. First, convert how many moles are there in 1.75g of carbon dioxide. Then, from the chemical equation you will know how many moles of sodium bicarbonate formed with 1 mole of carbon dioxide. Then convert the moles of sodium bicarbonate to grams using the molecular weight of the compound. You now have your answer.
Carbon cannot reduce sodium because sodium is stronger than carbon. reactive metals like sodium and potassium and electrolysis has to be used.
Answer:
The concentration of SO₂ will decreases
Explanation:
As you can see in the reaction
2 moles of gas ⇆ 3 moles of gas
Based on Le Châtelier's principle, a change doing in a system will produce that the system reacts in order to counteract the change made.
If the pressure is increased, the system will shift to the left in order to produce less moles of gas and decrease, thus, the pressure.
As the system shift to the left, the concentration of SO₂ will decreases
