Answer:

a system in chemical nomenclature and notation of indicating the oxidation state of the significant element in a compound or ion by means of a Roman numeral that is used in parentheses after the name or part of the name designating this element and ending invariably in -ate in the case of an anion and that is placed. Stock nomenclature for inorganic compounds is a widely used system of chemical nomenclature developed by the German chemist Alfred Stock and first published in 1919. In the "Stock system", the oxidation states of some or all of the elements in a compound are indicated in parentheses by Roman numerals.

An Arrhenius base is best defined as a. An Arrhenius base is best defined as a b.hydroxide acceptor. c.proton donor. d.substance

pentagon [3]

Answer: produce hydroxide ions

Explanation:

Arrhenius acids are substances which dissociate in water to give hydrogen ions.

For example: $HCl$ is an Arrhenius acid.

$HCl\rightarrow H^++Cl^-$

Arrhenius bases are substances which dissociate in water to give hydroxide ions.

For example: $NaOH$ is an Arrhenius base.

$NaOH\rightarrow Na^++OH^-$

An Arrhenius base is best defined as produce hydroxide ions

g What are the relative rates of diffusion of the three naturally occurring isotopes of krypton, 80Kr80Kr , 82Kr82Kr, and 83Kr83

emmasim [6.3K]

Solution :

According to the Graham's law of diffusion, we know that, the rate of the diffusion varies inversely to the molar mass of the gas, i.e.

Rate of diffusion, $r_d = \frac{a}{\sqrt M}$

where, the 'M' is the molar mass of the gas.

Now in the case of the isotopes of the Krypton,

Atomic mass of $^{80}Kr$ = 80 AMU

Atomic mass of $^{82}Kr$ = 82 AMU

Atomic mass of $^{83}Kr$ = 83 AMU

So the ratio of the rate of diffusion of the three isotopes are :

$M_{d,^{80}Kr}:M_{d,^{82}Kr}:M_{d,^{83}Kr}$

$=\frac{1}{\sqrt{80}}:\frac{1}{\sqrt{82}}:\frac{1}{\sqrt{83}}$

$=0.1118:0.1104:0.10976$

Dividing the above three with the smallest number among the three i.e. 0.10976, we get the relative rates of diffusion.

∴ $M_{d,^{80}Kr}:M_{d,^{82}Kr}:M_{d,^{83}Kr}$

= 1.02 : 1.01 : 1

Hence the relative rate of diffusion are :

$^{80}Kr(1.02)>^{82}Kr(1.01)>^{83}Kr(1.00)$

3,3,4-trimethylhexane, 2,3-dimethyl-2-butene, and 3-methyl-1-butyne identify as an alkane, alkene, or alkyne and sketch its stru

andrew-mc [135]

The first one is an alkane, the second is an alkene, and the third is an alkyne. The suffix of the compound tells you what kind of hydrocarbon it is.
