Answer:
The most common non-destructive visualization method for TLC plates is ultraviolet (UV) light. A UV lamp can be used to shine either short-waved (254nm) or long-waved (365nm) ultraviolet light on a TLC plate with the touch of a button

The arrangement of the elements in order of decreasing metallic character is: Rb, Zn, P, S, F, Ca, Co, Cr
<h3 /><h3>What are metals?</h3>
Metals are elements which are known by their special ability to form ions by a loss of electrons.
The increasing metallic character of metal is a measure of their ability to lose electrons.
Metallic character increases from right to left and down a group in the period table.
Metals are found to the left of the period table.
In conclusion, metals are known by their ability to lose electrons.

Answer: 25%
Explanation: According to the Florida Industrial and Phosphate Research Institute, Florida’s phosphate mining accounts for about 75% of the phosphate used in the United States, as well as about 25% phosphate used around the world. Although first mined in England in 1847, and used as fertilizer, In 1881, a civilian employee, J Francis Le Baron discovered Phosphate pebbles in peace river, and then, a hard rock phosphate district was discovered in north central Florida after that which began the Phosphate mining industry in Florida. Phosphorus rock supplies the phosphorus element in the fertilizer mix of nitrogen-phosphorus-potassium that is used as fertilizer to aid in growth of plants.
Answer:
O The number of oxygen atoms in the reactants used by this process equals the total number of oxygen atoms in the products.
Explanation:
The statement that best describes how photosynthesis follows the law of conservation of mass is that the number of oxygen atoms in the reactants used by this process is equal to the total number of oxygen atoms in the products.
The equation of photosynthesis reaction is given as:
6CO₂ + 6H₂O → C₆ H₁₂ O₆ + 6O₂
According to the law of conservation of mass, matter is neither created nor destroyed during the course of a chemical reaction.
By the virtue of this, the number of oxygen atom on both sides of the expression must be the same. Also, the number of carbon and hydrogen atoms must also be the same.
Answer:
<u>Nucleus</u> - The central part of the atom containing protons and neutrons.
<u>Electron</u> - A positively charged particle located in the nucleus of an atom.
<u>Proton</u> - A positively charged particle located in the nucleus of an atom.
<u>Electron Cloud</u> - The area of the at surrounding the nucleus where electrons can be found.
<u>Neutron</u> - a negatively charged particle that orbits the nucleus of an atom.
