Answer:

2.61

Explanation:

pH+pOH=14, so sub in 11.39 for pOH, then subtract it over to get pH=2.61

if you have any questions, leave them in the comments and i will try to answer them, if this helped, pls give brainliest.

A sealed flask contains Ne, Ar, and Kr gas. If the total pressure in the flask is 3.782 atm, the partial pressure of Ne is 0.435

spin [16.1K]

Answer:

$P_{Ar}=1.734atm$ = partial pressure of Ar

Explanation:

Acccoding to dalton's law of partial pressure total pressure of system is equal to alzebraic sum of all partial pressure.

$P_{total} =P_{Ne}+P_{Ar} +P_{Kr}$

$P_{total}=3.782atm$

$P_{Ne}=0.435 atm$

$P_{Kr}=1.613atm$

$P_{Ar}=P_{total}-P_{Ne}-P_{Kr}$

$P_{Ar}=3.782-0.435-1.613$

$P_{Ar}=1.734atm$ =partial pressure of Ar

How many moles are in 4.01x10^24 particles?

skelet666 [1.2K]

Answer:

6.64

Explanation:

so moles

$\frac{number \: of \: \: particles \: }{6.02 \times {10}^{23} }$

then do =4.01×10^24/6.02×10^23

you get the answer as 6.6445 u only need to write the answer to

3.S.F 6.64 moles

hope this make sense :)

A student forgot to read the label on the jar carefully and put potassium chloride in the crucible instead of potassium chlorate

lys-0071 [83]

<span>The object that was trying to be oxidized would end up being reduced. There would be no net reaction otherwise. The KCl would have simply melted after a long enough time and with the application of enough heat to the crucible.</span>
