<span>Cations mix with anions, so you know NH4+ won't mix with K+ and SO4(2-) won't miix with F-. For the reason that NH4+ and F- together have single charges, they'll mix in a 1:1 ratio, NH4F. There's two charges on SO4(2-), so it'll need two K+ to mix with, K2SO4.</span>
Answer:
A. = 143
B. = 8
C. =32
Explanation:
Number of neutron = mass number - atomic number
The answer would most likely be False
A) I-
An anion is is a negatively charged ion. :)
2. HF(aq) + K^(+)(aq) +OH^(-)(aq) → K^(+)(aq) + F^(-)(aq) + H_2O(ℓ)
<em>Step 1</em>. Write the <em>molecular equation
</em>
HF(aq) + KOH(aq) → KF(aq) + H_2O(ℓ)
<em>Step 2</em>. Write the <em>total ionic equation
</em>
HF and H_2O are <em>weak electrolytes</em>, so we write them as <em>molecules</em>.
HF(aq) + K^(+)(aq) +OH^(-)(aq) → K^(+)(aq) + F^(-)(aq) + H_2O(ℓ)
