Write a balanced chemical equation for the reaction of solid titanium (iv) oxide with hydrogen gas to form solid titanium (ii) oxide and liquid water. Express your answer as a chemical equation including phases.

explanation:

i think option no d is the correct answer

he would use the colour black

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
