The first one shows greater amplitude because there is more space between the waves. The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. In a sense, the amplitude is the distance from rest to crest. Similarly, the amplitude can be measured from the rest position to the trough position.
Different types of acid deposition are
sulphur dioxide
nitroges oxides
Synthesis, decomposition, single replacement and double replacement.
Synthesis- two or more reactants unite to form a single product
S (Sulfur) + O2 (Oxygen) ——> SO2 (Sulphur dioxide)
Decomposition- A single reactant is decomposed or broken down into two or more
CaCO3 (Calcium Carbonate) ——> CaO (Calcium oxide) + CO2 (Carbon dioxide)
Single replacement- A single free element replaces or is substituted for one of the elements in a compound. The free element is more reactive than the one its replaces.
Zn (Zinc) + 2 HCI (hydrochloric acid) ——> H2 (hydrogen) + ZnCl2 (Zinc Chloride)
Double replacement- This reaction type can be viewed as an "exchange of partners." For ionic compounds, the positive ion in the first compound combines with the negative ion in the second compound, and the positive ion in the second compound combines with the negative ion in the first compound.
HCI (hydrochloric acid) + NaOH (sodium hydroxide) ——> NaCl (Sodium Chloride) + HOH (water)
Once reactants have absorbed enough heat energy from their surroundings to reach the transition state, the reaction will proceed. The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be.
Just observing an physical property of a substance cant not change the substances identity. You can only figure out its identity through test and the figuring out of the elements! I hope I was of some help!!
