Would it make a difference if calcium bromide solution, cabr2, were used rather than sodium bromide solution?

1 answer:

<span>No it would not because solubility would not be affected since bromine is the only element in the reaction that is involved in the reaction.</span>

How many grams of O are in 605 g of Na,O?

Elden [556K]

Answer:

2Na2O2+2H2O⟶O2+4NaOH

2×78g 32g

156g of Na2O2 produces 32g of O2,

12g of Na2O2 produces =15632×12=10.66g.

Density of O2 at NTP=1.428g/mL.

DensityMass=Vol.

1.42810.66=7.46mL

Vol. of O2 at NTP is 7.46mL.

A ridged steel tank filled with 62.7L of nitrogen gas of 85.0L atm

mylen [45]

The final gas pressure : 175.53 atm

<h3>Further explanation</h3>

Maybe the complete question is like this :

A ridged steel tank filled with 62.7 l of nitrogen gas at 85.0 atm and 19 °C is heated to 330 °C while the volume remains constant. what is the final gas pressure?

The volume remains constant⇒Gay Lussac's Law

<em>When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature </em>

$\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$

P₁=85 atm

T₁=19+273=292 K

T₂=330+273=603 K

$\tt P_2=\dfrac{P_1\times T_2}{T_1}\\\\P_2=\dfrac{85\times 603}{292}\\\\P_2=175.53~atm$
