Answer:
b is the correct answer ok
Answer:
I think C option ✔️ ✔️ correct
Answer:
<u></u>
Explanation:
<u>1. Balanced chemical equation</u>
- Ba(OH)₂(aq) + 2HNO₃(aq) → Ba(NO₃)₂(aq) + 2H₂O(l)
<u />
<u>2. Determine the number of moles of HNO₃ in the solution</u>
- n = M × V = 0.425M × 0.050 liter = 0.02125 mol HNO₃
<u>3. Use the mole ratio from the balanced chemical equation and the number of moles of HNO₃ to determine the number of moles of Ba(OH)₂.</u>
<u>4. Determine the molar concentration of the solution of Ba(OH)₂</u>
- M = 0.010625mol/0.0368liter
93,000 in scientific notation is fairly simple, you're just breaking down the number a tad so you don't have to use a huge number!
BUT! In scientific notation 93,000 is 9.3x10^4 - written out that's nine point three times ten to the fourth power! (:
I hope all is well, and you pass! Good luck, rockstar! (: If you have any follow up questions, or even any comments - pm me or just let me know!
