Answer:
This substance is basic.
Explanation:
The milk of Magnesia, a type of medication which can help people with heartburn and with a pH of 10.5 is a basic solution.
- Bases are certain metallic oxides, metallic hydroxides and aqueous ammonia.
- They have the following properties:
- On the pH scale, they have a value between 7-14
- They turn red litmus paper blue.
- Bases are electrolytes.
- They have a bitter taste.
- They are soapy or slippery to feel.
When a large fissile atomic nucleus such as uranium-235 or plutonium-239 absorbs a neutron, it may undergo nuclear fission. The heavy nucleus splits into two or more lighter nuclei, (the fission products), releasing kinetic energy, gamma radiation, and freeneutrons
Answer:
The wavelength the student should use is 700 nm.
Explanation:
Attached below you can find the diagram I found for this question elsewhere.
Because the idea is to minimize the interference of the Co⁺²(aq) species, we should <u>choose a wavelength in which its absorbance is minimum</u>.
At 400 nm Co⁺²(aq) shows no absorbance, however neither does Cu⁺²(aq). While at 700 nm Co⁺²(aq) shows no absorbance and Cu⁺²(aq) does.
