Identify the name of the hydrated ionic compound, K₂CrO₄.3H₂O

Washing soda, a compound used to prepare hard water, is a hydrate, which means that a certain number of water molecules are included in its solid structure. Its formula can be written as Na₂CO₃ ⋅ xH₂O, where x is the number of moles of H₂O per mole of Na₂CO₃.

A 6.51 g sample of washing soda is heated at 125 °C, and all the water of hydration is lost, leaving 1.48 g of Na₂CO₃. What is the value of x?

Explosions using chemicals are accompanied by the release of hot gases, often seen by a shock wave traveling at speeds reaching 10300 m/s. Detonation of trinitrotoluene (TNT, C₇H₅N₃O₆) causes it to decompose and form the following gases: N₂, H₂, CO, and C. Write a balanced equation for the detonation of TNT.

Write the balanced reaction based on the molecules of a reaction shown below

Balance the equations below by adding the correct coefficients

_— CuO + _— CO → _— Cu + _— CO₂

_— Na₃N + _— H₂O → _— NaOH + _— NH₃

_— SeO₂ + _— O₂ → _— SeO₃

Decane (C₁₀H₂₂) is a component of diesel. Assuming diesel is 100% decane, the complete combustion of decane produces CO₂ and H₂O, and the density of decane is 0.73 g/mL, calculate the mass of CO₂ (in kg) produced if the yearly diesel consumption of the U.S. is 1.78 × 10¹¹ L.
