What is the value of 1.5 ATM of gas at 20°C and a 3 L vessel are heated at 30°C at a pressure of 5.2 ATM

vampirchik [111]

Answer:

The answer will be approximately 1.0L

Explanation:

The problem has not been properly specified. You could have specified a gas in a PISTON, whose volume would decrease with increased pressure, and increase with increased temperature.

For such a system, we would use the

combined gas law:

$\frac{P1V1}{T1}$ = $\frac{P2V2}{T2}$

$V_{2}$ = $\frac{P1V1}{T1}$ $\times$ $\frac{T2}{P2}$

= $\frac{1.5\times3.0\times303}{293\times5.2}$

$\approx$ 1.0L

write a skeletal equation for the following reaction: An aqueous solution of barium nitrate and an aqueous solution of sodium su

belka [17]

Answer: skeletal equation : $Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow NaNO_3(aq)+BaSO_4(s)$

The products are sodium nitrate and barium sulphate.

balanced equation : $Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow 2NaNO_3(aq)+BaSO_4(s)$

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The skeletal equation is:

$Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow NaNO_3(aq)+BaSO_4(s)$

The balanced chemical equation is:

$Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow 2NaNO_3(aq)+BaSO_4(s)$
