Answer:
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide.
Answer:
327.5 mmHg
Explanation:
By Boyle's law, P1V1=P2V2
10 L * 655 mmHg = 20 L * x
solve for x
x= (10*655)/20
x=327.5 mmHg
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!
Answer:
pH = 1.30
Explanation:
The reaction that would take place between HCl and NaOH is:
In this problem, the 0.1 moles of NaOH would react with 0.1 moles of HCl, <u>leaving 0.1 moles of HCl unreacted</u>.
These 0.1 HCl moles are dissolved in 2 liters, thus the concentration of H⁺ species is:
- [H⁺] = 0.1 mol / 2 L =0.05 M
Finally we <u>calculate the pH</u>:
Answer:
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.
Explanation:
They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.
