A 0.8kg object displaces 500ml of water what is its specific gravity
worty [1.4K]

Specific gravity is the ratio of density of substance and density of water

We know that density of water = 1 g /mL at standard conditions

now as given that the 0.8 Kg of the substance / object is able to displace 500mL of water , it means that

Mass of object = 800g

The volume occupied by 800g of object = 500 mL

Density = mass / volume

Density of object = 800 / 500= 1.6 g / mL

The specific gravity of object = density of object  / density of water = 1.6 / 1 = 1.6 (no units)

what is the diffrence between displacement ans double displacement reactions write equations for these reactions
Lina20 [59]

Answer:

Single Displacement reaction  

In a displacement reaction, a more reactive element replaces a less reactive element from a compound.

Change in colour takes place with no precipitate forms.

Metals react with the salt solution of another metal.

Examples:

2KI + Cl2 → 2KCl + I2

CuSO4 + Zn → ZnSO4 + Cu

Double displacement reaction

In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds.

Precipitate is formed.

Salt solutions of two different metals react with each other.

Examples:  

Na2SO4 + BaCl2 → BaSO4 + 2NaCl

2KBr + BaCl2 → 2KCl + BaBr2
