If 2.19 mol
never [62]

Answer:

1370 °C

Explanation:

We can use the Ideal Gas Law and solve for T.

pV = nRT

Data:  

p = 8.12 atm

V = 36.41 L

n = 2.19

R = 0.082 06 L·atm·K⁻¹mol⁻¹

Calculations

\begin{array} {rcl}pV & = & nRT\\\text{8.12 atm} \times \text{36.41 L} & = & \rm\text{2.19 mol} \times 0.08206 \text{ L}\cdot\text{atm}\cdot\text{K}^{-1}\text{mol}^{-1} \times T\\295.6&=&0.1797T\text{ K}^{-1}\\T& = &\dfrac{294.9 }{\text{0.1797 K}^{-1}}\\\\ & = & \text{1645 K}\\\end{array}

T = (1645 - 273.15) °C = 1370 °C

The temperature of the sample is 1370 °C.

Based on the results from this experiment, predict whether some of the following combinations of compounds would precipitate or
iren [92.7K]

Answer:

* No precipitate: LiOH(aq)+NaCl(aq)\rightarrow LiCl(aq)+NaOH(aq)

* Precipitate: 3BaCl_2(aq) +2Na_3PO_4(aq) \rightarrow Ba_3(PO_4)_2(s)+6NaCl(aq)

* Precipitate: MgSO_4(aq)+2KOH(aq)\rightarrow Mg(OH)_2(s)+K_2SO_4(aq)

Explanation:

Hello!

In this case, since these all are double displacement reactions, in which the cations and anions are exchanged, we can write the resulting chemical reactions as follows:

a. LiOH and NaCl: No precipitate is formed since LiOH and NaOH are both largely soluble in water:

LiOH(aq)+NaCl(aq)\rightarrow LiCl(aq)+NaOH(aq)

b. BaCl2 and Na3PO4: barium phosphate precipitate is formed because it has a large molar mass which makes it insoluble in water:

3BaCl_2(aq) +2Na_3PO_4(aq) \rightarrow Ba_3(PO_4)_2(s)+6NaCl(aq)

c. MgSO4 and KOH: magnesium hydroxide "milky" precipitate is formed because it is not soluble in water:

MgSO_4(aq)+2KOH(aq)\rightarrow Mg(OH)_2(s)+K_2SO_4(aq)

Moreover, we can relate the solubility of a substance by considering its polarity, molar mass and nature; usually, heavy substances tend to be insoluble in water as well as nonpolar compounds.

Best regards!

The number of moles in 2.93 g of Li2O in corrext sig figs​
jekas [21]

Answer:

0.1 mol

Explanation:

Number of mole= mass/molar mass

lithium have a mass number of 7 and oxygen have a mass number of 16.

so, (7x2) + 16

= 30

therefore, number of moles = 2.93/30

= 0.10
