Look up the active ingredient in baking soda. Write a molecular and net ionic equation when that active ingredient is mixed with

Volgvan

Answer:

The active ingredients in baking soda (NaHCO3) are

$Na^+$ and $HCO3^-$

when Baking soda reacts with Acetic acid

Molecular equation

NaHCO3(aq) + CH3COOH(aq) → Na(CH3COO)(aq) + CO2(g) +H2O(l)

Ionic equation

$Na^+ + HCO3^- + CH3COOH$ → $Na^+ + CH3COO^- +CO2 + H2O$

as $Na^+$ is present on both sides so it will cancel out and the net ionic equation will be

$HCO3^-(aq) + CH3COOH(aq)$ → $CH3COO^-(aq) + CO2(g) + H2O(l)$

55 L of a gas at 25oC has its temperature increased to 35oC. What is its new volume?

ladessa [460]

Answer:

Approximately 56.8 liters.

Assumption: this gas is an ideal gas, and this change in temperature is an isobaric process.

Explanation:

Assume that the gas here acts like an ideal gas. Assume that this process is isobaric (in other words, pressure on the gas stays the same.) By Charles's Law, the volume of an ideal gas is proportional to its absolute temperature when its pressure is constant. In other words

$\displaystyle V_2 = V_1\cdot \frac{T_2}{T_1}$ ,
