It's a saline solution, commonly used in many ways, primarly in chemistry and medicine (i.e. in intravenous therapy, nasal lavage or in biological and chemical experiments), but also for cleaning new piercings or rinsing contact lenses.
Solution :
Millimoles of hydrocyanic acid = 225 x 0.368
= 82.8
Millimoles of potassium cyanide = 225 x 0.360
= 81
Millimoles of sodium hydroxide = 51.3
Therefore,
pOH = pKb + log [salt - C / bas + C]
= 4.74 + log[82.8 - 51.3 / 81 + 51.3]
= 4.102
Therefore, pH = 9.05
Wooahhhh pollution can affect the environment and urself pollited water can affect marine animals and can result them in extinction global warmning melts Antarctica and can cause floodigs and extinction there. This probably wont help but i just free styled lol
Goodluck
Answer:
The answer to your question is letter D.
Explanation:
Bohr tells us that the electrons which have a negative charge clicle the orbits in specific nucleus, so the right answer is letter D.
Letter C is not possible because the electrons are in orbits circling the nucleus where the protons are.
Letter B is not correct because electrons are distributed in orbits but the amount of electrons in one orbit is different to the other one.
Answer:
The answer to your question is:
Explanation:
Ionic compound is formed when a metal and a nonmetal are attached.
If we have MgX₂, that means that the nonmetal must have a valence of -1.
From the list the nonmetals with a valence of -1 are:
Bromine(Br) and fluorine(F).
