Explanation:
pH is used to measure the concentration of H+ ions ([H+]) and therefore, whether a substance is acidic or basic (alkaline). Solutions with a pH of less than seven are acidic, while those with a pH greater than seven are basic (alkaline).
The chemical equation that correctly represents the synthesis of calcium sulfite is
CaO(s) + SO₂(g) → CaSO₃(s)
<u><em>Explanation</em></u>
<u><em> </em></u>Synthesis reaction is type of chemical reaction in which two or more simple substance combine to form a more complex product.
The reaction above is therefore a synthesis reaction since CaO and So₂ combine to form CaCO₃ ( a complex product)
I did this when I was younger
PV = nRT
P is pressure, V is volume, n is number of moles, R is the gas constant, T is temperature in K
(2.85 atm)(12.5 L) = (n)(.08206)(27 C + 273)
n = 1.45 moles x 35.45 grams / mol Cl2 = 51.3 grams
