The answer is a traveling wave
Travelling waves are temporary waves and these occur for a very short duration and move with constant speed. It is represented by an infinite rectangular waves. The crest of travelling wave move in wave propagating direction. Mathematically a periodic travelling wave is a one dimensional space that moves constantly with unvarying velocity through some medium.
Answer:
Chloride (Cl⁻) and sodium (Na⁺) ions.
Explanation:
Hello,
In this case, since the aqueous species are actually dissociated when reacting and the solid species (ferric carbonate) remains undissolved, we can modify the given reaction as follows:
In such a way, dissociating the aqueous species we obtain:
It means that the net ionic equation is:
Therefore, the spectator ions are those were cancelled out, chloride (Cl⁻) and sodium (Na⁺).
Best regards.
<span>1)
Calculate [H+] from the pH:
pH = log { 1 / [H+] } = - log [H+]
=> [H+] = 10 ^ (-pH)
=> [H+] = 10 ^ (-2.80) = 0.00158
2) Assume the stoichiometry 1:1
=> HA aq ---> H(+) aq+ A(-) aq
=> [A-] = [H+] = 0.00158
[HA] = 0.294 – 0.00158 = 0.29242
3) Calculate Ka</span>
<span>Ka = [H+] *[A-] / [HA] = (0.00158)*(0.00158) / 0.29242 =8.54 * 10^ -6
Answer: 8.5 * 10^ -6</span>
1, they were wrong sometimes
2. people don't trust him
