Raindrops take up the spherical shape due to the surface tension of water which is caused due to the   tendency  of water molecules to stick together. The spherical shape is having the least possible surface area due to which it can resist any of the external force in the atmosphere.

  • The law states that in a chemical substances the elements are always present in a definite proportion by mass. It is also termed as law of definite proportion.
  • For instance, the ratio of hydrogen and oxygen in water obtained from any source is 1:8 i.e. 1g of hydrogen and 8g of oxygen together make up 9g of water.
  • Similarly the ration of nitrogen and hydrogen in ammonia is 14:3.

The axillary bud (or lateral bud) is an embryonic or organogenic shoot located in the axil of a leaf. Each bud has the potential to form shoots, and may be specialized in producing either vegetative shoots (stems and branches) or reproductive shoots (flowers). Their main function is to provide support to the plant, holding leaves, flowers, and buds; in some cases, stems also store food for the plant. An axillary bud is usually found in the axil (the area between the base of a leaf and the stem) where it can give rise to a branch or a flower.

Subtract the later vector from the earlier, and divide by the infinitesimally small time interval. The resulting vector is the instantaneous acceleration (in the limit that the time interval goes to zero). The direction of that vector is the direction of the acceleration.

Equilibrium in Chemical Processes You may have learnt about reversible reactions. As the name suggests, these reactions occur in the forward and reverse direction. In such reactions, when the rate of the forward and reverse reaction is equal, the concentrations of the reactants and products remain constant. At such a stage, the reaction is said to be in chemical equilibrium. However, this equilibrium is said to be dynamic in nature. This is because it consists of a forward reaction where the reactants react to give products and reverse reaction where the products can react to give back the original reactants. Let’s understand these chemical processes below. Dynamic Nature of Chemical Processes in Equilibrium Let’s consider the following reversible reaction – A + B ⇌ C + D As time progresses, the products (C and D) accumulate while the reactants (A and B) deplete. This results in a decrease in the rate of the forward reaction and an increase in the rate of reverse reaction. Ultimately, both reactions occur at the same time reaching a state of equilibrium. This equilibrium can be reached from either direction. Haber’s Process The German chemist, Fritz Haber developed a method to manufacture ammonia from dinitrogen and dihydrogen. This process is the Haber’s process. N2(g) + 3H2(g) ⇌ 2NH3(g) Haber started out with known amounts of dinitrogen and dihydrogen, maintained at high temperature and pressure, and noted the amount of ammonia produced at regular intervals. As the reaction proceeds, after some time, he noted that the composition of the mixture remains the same even though some reactants are still present. This shows that the reaction has reached equilibrium. chemical equilibrium Haber’s process [Source: Wikimedia Commons] Further, Haber’s process demonstrates the dynamic nature of chemical equilibrium in the following manner. Keeping the experimental conditions same as above, hydrogen (H2) was replaced with deuterium (D2). This gives rise to ND3 as the product instead of NH3. Both reactions, one involving H2 and one with D2 were allowed to proceed to equilibrium. When these two mixtures (H2, N2, NH3 and D2, N2, ND3) were mixed and left for a while, it was observed that the concentration of ammonia was the same as before. Although, mass spectrometry revealed that along with ammonia, all forms containing deuterium and dihydrogen were present (NH2D, NHD2, ND3, H2, HD and D2). This shows that the scrambling of H and D atoms must be possible due to the continuation of the forward and reverse reactions. There would have been no mixing of isotopes if the reaction had stopped on reaching equilibrium. Therefore, chemical reactions reach a state of dynamic equilibrium in which the rates of forwarding and reverse reactions are equal and there is no net change in composition. Chemical Equilibrium is Bidirectional Whether we start a reaction using reactants or products, equilibrium is attainable from both sides. Let’s consider the following reaction. H2(g) + I2(g) ⇌ 2HI(g) If we start the reaction with equal initial concentrations of H2 and I2, then the reaction proceeds in the forward direction where the concentration of H2 and I2 decreases and that of HI increases until it reaches equilibrium. If we start the above reaction in the reverse direction, then the concentration of HI decreases while that of H2 and I2 increases till it reaches equilibrium. Therefore, if the total number of atoms of an element are same in a given volume, we get the same equilibrium mixture whether we start it with reactants or with products

Gluon, the so-called messenger particle of the strong nuclear force, which binds subatomic particles known as quarks within the protons and neutrons of stable matter as well as within heavier, short-lived particles created at high energies. Quarks interact by emitting and absorbing gluons, just as electrically charged particles interact through the emission and absorption of photons.
