Answer:
Explanation:
2HCl = H₂ + Cl₂
2 mole 1 mole 1 mole
73 gram HCl = 73 / 36.5 = 2 mole of HCl
2 moles of HCl will produce 1 mole of chlorine gas .
At STP , one mole of chlorine gas has volume equal to 22.4 litre .
Answer:
Cadmium +p= 48
Titanium p=22
Oxygen p=8
Krypton p=36
So the answer is Cadmium which has #48 protons
Explanation:
Gravity is the force that keeps the planets in orbit.
When a bond is broken that should be a type of reaction. When bonds are broken sometimes heat is released.
Answer:
C. 1 cubic foot of loose sand
Explanation:
For many objects having equal volume , surface area will be maximum
of the object which has spherical shape .
But when a sphere is broken into tiny small spheres , total surface area of all the small spheres will be more than surface area of big sphere .
Hence among the given option , surface area of loose sand will have greatest surface area . Loose sand is equivalent to small spheres .
