Baking soda, NaHCO3, can be commercially produced during a series of chemical reactions called the Solvay process. In this proce
Mnenie [13.5K]

Answer:

CaO(s) + 2NH4Cl(aq) -------> CaCl2(aq) + H2O(l) + 2NH3(g)

Explanation:

The solvay process is an important process in the chemical industry. In this process, ammonia gas is first dissolved in concentrated brine to form a mixture known as ammoniacal brine. This solution is made to trickle down the tower. A counter stream of carbon dioxide is forced up the tower. The two substances react to form sodium hydrogen trioxocarbonate IV. This substance is only slightly soluble and separates out as a solid sludge. The product is now dried and heated to give sodium trioxocarbonate IV.

The overall reaction of the process can be given as;

CaO(s) + 2NH4Cl(aq) -------> CaCl2(aq) + H2O(l) + 2NH3(g)

Calcium chloride is merely a by-product.

Will you be my Magnesium, Silver, Nitrogen but "9.8m/s²" is silent? <br> Please help me here
zmey [24]
I don’t really understand but the symbols of these elements on the periodic table are

MgAgN

and 9.8 m/s^2 is the acceleration of gravity, commonly abbreviated as ‘g’

If you take out the ‘g’s from the periodic table equation(bc the question says 9.8m/s^2 is silent) it spells MAN

So the question could be “Will you be my man?”
