after 2 hl its quarter remaining
after 3 hl its half the quarter which is 1 eighth
after 3 half lifes
Answer:
The more optically dense that a material is, the slower that a wave will move through the material. ... So as the index of refraction value increases, the optical density increases, and the speed of light in that material decreases.
Answer:
All of the physical and biological factors in it's environment, I think this is the answer, but I might be wrong.
Explanation:
I learned it in my school's Science class
The element cesium forms a positive ion with the charge +1 . The symbol for this ion is Ce⁺, and the name is cesium ion. The number of electrons in this ion is 54.
<h3>What group does the element cesium belong to in the periodic table?</h3>
Cesium belong to the Group 1A of the periodic table.
Group 1A elements are known as alkali metals.
The alkali metals react with water to form alkalis. They form ions with a positive charge of +1 by the loss of an electron.
In conclusion, cesium is an alkali metals it belongs to group 1A of the periodic table. It forms a positive ion with a charge of +1 by the loss of an electron.

<span>You can't substitute that. Substitution is a reaction between acid and metal. Acid+metal ---> salt+H2
example : H2SO4+Al ---> Al2(SO4)3+H2 so,substitution of hno3 solution for 3M h2so4 is not possible</span>
