Mekhanik [1.2K]

Answer:

When you open the bottle, there is a dramatic decrease in pressure over the liquid, so the CO2 starts to leave the liquid very rapidly, causing the mass exodus of gas, or "explosion" of bubbles. This also explains why soda goes flat.

Calculate the mass of silver bromide produced from 22.5 g of silver nitrate.
Orlov [11]
Equation is as follow,

<span>                     2 AgNO</span>₃<span>  +  MgBr</span>₂<span>    </span>→    <span>2 AgBr  +  Mg(NO</span>₃<span>)</span>₂

According to eq.

    339.74 g (2 moles) AgNO₃ produces  =  375.54 g (2 moles) of AgBr
So,
                    22.5 g AgNO₃ will produce  =  X g of AgBr

Solving for X,
                             X  =  (22.5 g × 375.54 g) ÷ 339.74 g

                             X  =  24.87 g of AgBr
