=Spectral lines are produced by transitions of electrons within atoms or ions. As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed.…
Answer:
Volume of NaOH reacted = 1.6 L
Explanation:
<u>Given:</u>
Molarity of H2SO4, M1 = 4.0 M
Volume of H2SO4, V1 = 0.6 L
Molarity of NaOH, M2 = 3.0 M
<u>To determine:</u>
Volume of NaOH,V2
<u>Explanation:</u>
The given neutralization reaction is:
Here 2 moles of NaOH reacts with 1 mole of H2SO4
i.e. moles of NaOH = 2(moles of H2SO4)
Since:
Answer:The majority of chemical processes are reactions that occur in solution. Important industrial processes often utilize solution chemistry. "Life" is the sum of a series of complex processes occurring in solution. Air, tap water, tincture of iodine, beverages, and household ammonia are common examples of solutions.
A solution is a homogenous mixture of substances with variable composition. The substance present in the major proportion is called the solvent, whereas the substance present in the minor proportion is called the solute. It is possible to have solutions composed of several solutes. The process of a solute dissolving in a solute is called dissolution.
Explanation:
(i) Assume that CuSO₄ + H₂O was the reaction that happened in that dish. Copper sulfate is anhydrous, so if water is added, it becomes copper sulfate pentahydrate.
CuSO₄(s) + H₂O(l) = CuSO₄ · 5H₂O(s)
Copper sulfate is soluble in water, so copper and sulfate both become aqueous. Copper sulfate has become crystallized, and the water has become attached to it.
(ii) As seen in my equation of (i), all that is left in the dish is a solidified, blue crystallized version which has a octahedral molecular geometry.
