Answer:
We hope your visit to math.com brings you a greater love of mathematics, both for its beauty and its power to help solve everyday problems.
Einstein, Albert (1879-1955)
Do not worry about your difficulties in mathematics, I assure you that mine are greater.
Dirac, Paul Adrien Maurice (1902-1984)
Mathematics is the tool specially suited for dealing with abstract concepts of any kind and there is no limit to its power in this field.
Egrafov, M.
If you ask mathematicians what they do, you always get the same answer. They think. They think about difficult and unusual problems. They do not think about ordinary problems: they just write down the answe
Explanation:
The pH value can be measured using electrochemical measuring systems, litmus paper, or indicators and colorimeters. The easiest way to take a pH measurement is to use litmus paper or a colorimeter. The advantage of this type of pH measurement is that the pH range is well known and they are easy to apply.
The benefits are with the aid of equipment work load is reduced therefore it is great to have as many aiding tool to assist on work
I'm assuming false but really have no clue
Answer:
Redox type
Explanation:
The reaction is:
2Cr + 3Fe(NO₃)₂ → 2Fe + 2Cr(NO₃)₃
2 moles of chromium can react to 3 moles of iron (II) nitrate in order to produce 2 moles of iron and 2 moles of chromium nitrate.
If we see oxidation state, we see that chromium changes from 0 to +3
Iron changed the oxidation state from +2 to 0
Remember that elements at ground state has 0, as oxidation state.
Iron is being reduced while chromium is oxidized. Then, the half reactions are:
Fe²⁺ + 2e⁻ ⇄ Fe (Reduction)
Cr ⇄ Cr³⁺ + 3e⁻ (Oxidation)
When an element is being reduced, while another is being oxidized, we are in prescence of a redox reaction.
