Describe where a hydrogen bond can form among water molecules.
stiv31 [10]

Answer:

                 In water hydrogen bonding formed between partially negative oxygen and partially positive hydrogen atoms.

Explanation:

                  Hydrogen bond is a partially electrostatic attraction between hydrogen (H), which is bonded to a more electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F), and another adjacent atom bearing a lone pair of electrons.

                   In water molecule hydrogen and oxygen have difference in electronegativity, due to which dipoles are form. One is partial positive on hydrogen atom and other is partial negative on oxygen atom. The electrostatic attraction occur between two oppositely charged poles which is known as hydrogen bonding.

2. What's the kinetic energy of an object that has a mass of 12 kilograms and moves with a velocity of 10 m/s?
Dennis_Churaev [7]
<h2>Let us solve for it </h2>

Explanation:

Energy

It is ability to do work .

There are so many forms of energy .

out of which mechanical energy is also one of the form .

Mechanical energy

It is the energy possessed by the body by virtue of its motion and state .

It is of two types :

  • Kinetic energy
  • Potential energy

Kinetic energy

It is the energy possessed by the body by virtue of its motion .

Its expression is :

K.E=1/2mv²

Here in above question it is given that :

mass = 2Kg

V=10m/sec

K.E will be = 1/2 x 2 x 10 x 10

K.E=100 J

How to know whether something is an "atom" or not? for example
Karolina [17]
A normal atom has a neutral charge with equal numbers of positive and negative particles. That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons.
