Answer:
Explanation:
The rate of the forward reaction is less than the rate of the reverse reaction. ... The reaction rates of the forward and reverse reactions are equal
Yes layers of sediment form at the bottom of the ocean.
Answer:
Refinement
Explanation:
The 3R's policy was fundamentally introduced to safeguard the animals from harsh experiments which could change their mental and physical abilities and lead to their extinction one day.
The principles of 3R's (Replacement , Reduction and Refinement) were developed long time ago. It is an strategy to perform more Humane animal research.
These are defined as,
Replacement is a method to avoid or replace the uses of animals.
Reduction is a method to minimize the number of animals used every experiment.
Refinement is a method of minimizing animal suffering and improving welfare.
Explanation:
1. Democritus proposes the existence of atoms
2. Dalton's atomic theory
3. J. J. Thomson discovers the electron
4. Rutherford's gold foil experiment
5. Bohr model
6. Schrödinger's Wave Mechanics model of the atom
The first idea about matter containing atoms dates back to Greek philosophers. One of them was Democritus .
In 1808 Dalton put forward his atomic theory
In 1897 J.J Thomson discovered cathode rays using his gas discharge tube experiment.
In 1911, Ernest Rutherford proposed the nuclear model of the atom using experiments on the gold foil.
Neils Bohr in 1913 suggested his own atomic model
Erwin Schrodinger formulated the wave equation of electrons

#4 and #5:
To find pH given concentration of H+ or H30+
pH = - log (H+ or H30+ M)
To find pH given concentration of OH-
Since you already found the pH for this (in #4), you subtract #4's answer from 14.
14 - (pH) = pOH
