Write a balanced chemical equation for the standard formation reaction of solid sodium carbonate

2Na(s) + C(s) + 3/2 O2(g) > Na2CO3(s).

Explanation:

Balancing and writring chemical reactions in Chemistry is a very important aspect of chemistry and,

writting and balancing of chemical reaction is often regarded as the heart of chemistry. A balanced Chemical reaction shows the number of each species in a reaction.

Hence, the balanced chemical equation for the standard formation reaction of solid sodium carbonate is given below;

(1). The reaction(unbalanced Reaction):

Na(s) + C(s) + O2(g) > Na2CO3(s).

Where solid sodium carbonate = Na2CO3(s).

(2). Balanced Reaction;

2Na(s) + C(s) + 3/2 O2(g) > Na2CO3(s)

what are the two models

explanation:

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
