Answer:
Explanation:
A covalent compound is made when two or more nonmetal atoms bond by sharing valence electrons. The shared valence electrons between two nonmetal atoms is called a covalent bond. Covalent bonds are formed when two atoms begin sharing electrons
Answer:
Explanation:
The formula of nickeI(II)nitrate hexahydrate is
Ni(NO3)2.6H2O
So option (c) is correct.
Answer:
When water forms beads on a surface, as it does on the hood of a freshly waxed car, we can say that the water is <u>minimizing</u> its contact with the surface because the cohesive forces are <u>larger</u> than the adhesive forces
Explanation:
A waxed car's surface is covered wax which is an hydrocarbon having long chains that are very hydrophobic and therefore there is little interaction between the surface covered in wax and the cohesive forces in the water is much larger than the adhesive forces between the water and the freshly waxed car's surface which makes the water bead up to minimize the contact surface with the car's metal surface that results in limiting of the rust.
Answer:
Net force= -5N+5N =0
Therefore there is no change in motion
