Electrons in an atom are found on different electron shells depending on how much energy they possess, and they determine how atoms will interact with each other. The outermost electron shell holds the valance electrons.
Answer: No
Explanation: It's not balanced because four oxygen atoms in H2SO4, whereas there are 5 oxygen atoms in the reactants side. Also, there's more hydrogen atoms on the reactants side.
I hope this helps!
Constant. you have to continuously apply the same amount of force to achieve constant velocity
The following aqueous solutions represents good buffer systems:
- 0.22 M acetic acid + 0.15 M potassium acetate
- 0.29 M ammonium nitrate + 0.32 M ammonia
<h3>What is a buffer?</h3>
A buffer is a solution used to stabilize the pH (acidity) of a liquid.
A good buffer system is generally known to contain close or equal concentrations of a weak acid and its conjugate base.
Based on the above explanation, the following represents a good buffer system as they are between their weak acid and conjugate base:
- 0.22 M acetic acid + 0.15 M potassium acetate
- 0.29 M ammonium nitrate + 0.32 M ammonia
