Im not really sure if those r right.
It may be right actually.
"4 d 10th time, guys! I'm not talking about a political party but the 46th element! Palladium!" :) Maybe? That's a hard one to do. Couldnt you do mercury? I have a wonderful joke for that one.
Why coudnt mercury hold still in class?
A. Because it was 80Hg! (get it? Say it vocally :) Sounds like ADHD right?)
PCL5[l]+4H2O=H3PO4+5HCL
CHECK;
on the L.H.S
P=1
CL=5
H=8
O=4
On the R.H.S
P=1
CL=5
H=8
O=4
<span>This question is answered using ideal gas model.
At constant temperature you can state that pV is constant. This is the p and V are inversely related. Then if the pressure doubles the volumen will be half. In this case:
(pV)1 = (pV)2 => V1 = (pV)2 / V2 = 50kPa*5.0L / 125kPa = 2.
Then the answer is the option c. 2.0 L</span>
Answer:
1.196 M NaOH
Explanation:
Molarity = moles/Volume (L)
moles NaOH = mass NaOH/MM NaOH = 12/40.01 = 0.299 moles NaOH
Volume solution = 250 mL = 0.250L
M = 0.299/0.250=1.196 M NaOH
