<span>This type of salt is called a hydrated salt. This specific salt is called Cobalt (II) chloride hexahydrate. Hydrated salts is a salt has a number of water molecules associated with the ions in its crystalline structure.</span>
Answer : The number of moles of added must be, 0.37 mol
Explanation :
The given chemical reaction is:
Initial mol. 2.99 x 0 0
At eqm. (2.99-1.30) (x-1.30) 1.30 1.30
= 1.69
The expression for equilibrium constant is:
Now put all the given values in this expression, we get:
x = 1.67 mol
The moles of added = (x-1.30) = (1.67-1.30) = 0.37 mol
The ignition occurs when a mixture of fuel & oxygen encounter an external heat source with sufficient heat<u> Piloted ignition.</u>
<h3>
What is Piloted ignition?</h3>
When a volatile fuel is close to a nearby local energy source (pilot) and reaches its lower limit of flammability in air, piloted ignition may be possible. The flame that originates in the premixed system spreads outward from the pilot. The first law of thermodynamics for systems with fixed mass only describes the energetics of this process.
<h3>Definition of thermodynamics </h3>
The science of thermodynamics examines how heat, work, temperature, and energy are related. The general topic of thermodynamics is the transfer of energy from one location or form to another. The fundamental idea is that heat is a type of energy that is equivalent to a specific quantity of mechanical labor.

Answer:
A. Oxygen is an element because its most basic unit is a single type of atom.
Explanation:
Oxygen is the chemical element with the symbol O and atomic number 8.
The specific heat capacity of sand is much less than water because of which sands require less energy to cool down and similarly less energy to be heated... because of this it feels like sands absrob heat faster than water
