A bag of potato chips contains 585 mL of air at 20.0 C and a pressure of 765 mmHg. Assuming the bag does not break, what will be
Scorpion4ik [409]

Answer:

volume = 972.23ml

Explanation:

using general gas law

P1V1/T1 = P2V2/T2

765 x 585/293 = 443 x V2/282

1527.39 =443 x V2/282

1527.38 x 282 = 443 x V2

430695.78 = 443 x V2

V2 = 430695.68/443

V2 = 972.23mL

Can you help me balance this​
Zepler [3.9K]

Balanced equation

Mg₃(PO₄)₂ + 2Al(NO₃)₃ → 3Mg(NO₃)₂ + 2AlPO₄

<h3>Further explanation</h3>

Given

Reaction

Mg3(PO4)2 + Al(NO3)3 → Mg(NO3)2 + AlPO4

Required

Balanced equation

Solution

Give a coefficient :

Mg₃(PO₄)₂ + aAl(NO₃)₃ → bMg(NO₃)₂ + cAlPO₄

Make an equation :

Mg, left = 3, right=b⇒b=3

P, left=2, right=c⇒c=2

Al, left=a, right=c⇒a=c⇒a=2

The reaction becomes :

Mg₃(PO₄)₂ + 2Al(NO₃)₃ → 3Mg(NO₃)₂ + 2AlPO₄
