Some people weren't convinced with the theory. Also many people tried to prove that the atom didn't exist, or at least prove the theory wrong.
Answer:
This depict that the growth of the new plant has taken place due to asexual form of reproduction.
Explanation:
A procedure in which new offspring is generated from a single parent without involving sex cells or gametes is known as asexual reproduction. One of the asexual forms of reproduction in plants is the artificial propagation of plants. The three general procedures of artificial propagation of plants are layering, cuttings, and grafting.
In cutting, a novel plant is developed by incising a small section of a plant that can be anything comprising bud on it. This section of the plant is then watered and grown into soil, and after some days a new plant begins to grow.
When 0.5 moles of Zn react with 0.4 moles of HCL the limiting reactant will be HCL and excess reactant is Zn 0.3 moles excess and 0.2 moles Zn will be consumed in the reaction.
<h3>What is the limiting reactant in the given equation ?</h3>
STEP1- Write the balanced equation
Zn + 2HCL → ZnCl₂ + H₂
STEP2- calculate the moles according to the reaction
1mol of Zn requires → 2moles of HCL
0.5 moles of Zn requires→ 1mol of HCL
Given moles of HCL is 0.4
STEP3- Apply unitary method
0.5/x=1/0.4
0.5×0.4= x
0.2=x
STEP4- excess reagent left 0.5-0.2=0.3
Hence, the 0.3mole of excess Zn is left

Physicist Ernest Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.
