243 grams of zinc oxide would be produced by the thermal decomposition of 375 grams of zinc carbonate.
<h3>What is Thermal Decomposition?</h3>
Heat causes one component to break down into two or more other substances in a process known as thermal decomposition. The heat is used to dissociate the bonds that held the original molecules' atoms together, hence the reaction often uses up more heat energy than it produces.
According to the periodic table:
zinc molar mass is 65.38 grams
12 gm is the molar mass of carbon
oxygen molar mass is 16 grams
ZnCO3 molar mass is 65.38 + 12.3 + 16.4 = 125.38 gm.
ZnO has a molar mass of 65.38 + 16 = 81.38 grams.
Therefore, the mass of ZnO in 375 gm is equal to (375 x 81.38) / 125.38, or 243.4 gm.

A good first step is writing the amount in terms of ml.
19.2 gallons = 72.68 L = 72680 ml
that would mean it weighs 0.749*720680g = 54437.32ml = 54.437 L
hope that helps :)
I think the Answer is C because Flourine is stronger in electron attraction and is smaller so it has a stronger electronic pull. Hope this helps :)
