Answer:0.005M
Explanation:
First deduce the oxidation and reduction half equations and from that obtain the balanced redox reaction equation. From that, the number of moles of reacting species are seen from the stoichiometry of the reaction from which the number of moles of oxalate is obtained and substituted to obtain the molar concentration of oxalate.
The postulates of Dalton's theory were:
1) Elements are made of extremely small particles called atoms
2) <span>Atoms of a given element are identical in size, mass, and other properties
</span>3) <span>Atoms cannot be subdivided, created, or destroyed</span>
4) Atoms combine in whole number ratio to form compounds
5) Chemical reactions are the rearrangement of atoms
The third postulate has been disproved by modern science, in which the atom has been split and been subdivided into smaller parts such as the neutron, proton and electron, which are further subdivided into quarks, gluons, and kaons.
The second postulate was also disproved upon the discovery of isotopes.
Answer: There are C - C bonds and C - H bonds.
trust me! I took a test with this question and got 100! :)
B) They have protons that are identical to the protons of all other elements
A chemist is using a solution of HNO₃ that has a pH of 3.75. what is [H⁺] for the solution is 1.7 × 10⁻⁴M.
<h3>How do we calculate the [
H⁺]?</h3>
Concentration of H⁺ ion will be calculated by using the below equation of pH as:
pH = -log[H⁺]
or [H⁺] = 
Given that, pH = 3.75
So concentration of H⁺ ion will be calculated as:
[H⁺] = 
[H⁺] = 1.7 × 10⁻⁴M
Hence concentration of H⁺ ion is 1.7 × 10⁻⁴M.
