1) 2K(s) + 2H₂O(l)→ 2KOH(aq) + H₂<span>(g)
This is a single replacement reaction where K reacts with H</span>₂O , displaces the H⁺ ion in water and combines with OH⁻ to form a base.
<span>
2) 2B</span>i(NO₃)₃(aq) + 3H₂S(g)→ Bi₂S₃(s) + 6HNO₃<span>(aq)
</span>This is a double displacement reaction where the ions are exchanged and form new compounds. Since ions are exchanged between 2 compounds its called double displacement.
3) 2HNO₃<span>(aq) + Ba(OH)</span>₂<span> → Ba(NO</span>₃<span>)</span>₂<span>(aq) + 2H</span>₂O<span>(l)
This is an acid base reaction where nitric acid and barium hydroxide react to form the respective salt and water</span>
Answer:
1 mole is equal to 1 moles Potassium, or 39.0983 grams.
39.0983g X 4 = 156.3932
so 4 moles are in 156 grams of Potassium
Explanation:
Hope this helps

Answer:
Explanation:
Catalyst is I2 . Because I2 is reacted with starting material in step 1 and generated in second step
Rate limiting step is step 1. Because in rate equation CH3CHO and I2 is mentioned. Hence the overall rate of reaction is depending CH3CHO and I2. Rate limiting step is step 1
Wilma- tt
Wilbur- TT
c) 100% chance
d) 100% chance
it has been a while since I've done this so it could be wrong but im pretty sure its correct
Wilbur's family claims it is pure so they have TT
and his wife simply has big eyes so its tt
so the chances of their children having either eye shape is 100%
I'm sorry- im not too good at explaining it ><
