sodium ion and calcium ions produce nearly the same color in a flame test. Describe a way to differentiate between the two using

a solution of Na2CO3 and write a balanced equation

To different sodium from calcium ions, we can add sodium and calcium ions separately to Na2CO3. On the sodium ion side, there will be no reaction while with Ca 2+ ions, the product resulting from the reaction will be CaCO3 via single replacement reaction. CaCO3 is a precipitate which makes the difference between the two ions.

posledela
Acetic acid is 60.05 grams/mole. In 1 liter of vinegar or 1000 ml  there would be 0.046% of acetic acid = 46 ml x 1.005g/ml = 46.23 grams/60.05 grams= 0.77 moles per litre of vinegar.This then would be the concentration of acetic acid in for example 1 liter of vinegar.

2.0 mol of gas occupy 44.8 l at a temperature of 0°c. what is the pressure of the gas
MArishka [77]

The pressure of the gas is 1.0 bar.

<em>pV</em> = <em>nRT</em>

<em>T</em> = (0 + 273.15) K = 273.15 K

<em>p</em> = (<em>nRT</em>)/<em>V</em> = (2.0 mol × 0.083 14 bar·L·K⁻¹mol⁻¹ × 273.15 K)/44.8 L = 1.0 bar
