No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical.

Softa [21]

Answer : The concentration of NH_4^+ ion is 0.15E^1M

Explanation :

First we have to calculate the moles of (NH_4)_3PO_4.

\text{Moles of }(NH_4)_3PO_4=\text{Concentration of }(NH_4)_3PO_4\times \text{Volume of solution}=0.50M\times 0.06L=0.03mole

The balanced chemical reaction will be:

(NH_4)_3PO_4\rightleftharpoons 3NH_4^++PO_4^{3-}

From the reaction we conclude that,

1 mole of (NH_4)_3PO_4 dissociate to give 3 moles of NH_4^+ ion and 1 mole of PO_4^{3-} ion

So,

0.03 mole of (NH_4)_3PO_4 dissociate to give 3\times 0.03=0.09 moles of NH_4^+ ion and 0.03 mole of PO_4^{3-} ion

Now we have to calculate the concentration of NH_4^+ ion.

\text{Concentration of }NH_4^+=\frac{\text{Moles of }NH_4^+}{\text{Total volume}}

\text{Concentration of }NH_4^+=\frac{0.09mole}{0.06L}=1.5M=0.15E^1M

Therefore, the concentration of NH_4^+ ion is 0.15E^1M

20 grams of ethane (C2H6) in a 15 L container has a pressure of 1.3 bar. What is the temperature, in oC
Zepler [3.9K]

Answer:

The temperature is 42.5 °C

Explanation:

We apply the Law of Ideal Gases to solve this:

P  .  V = n .  R . T

First, we convert the bar into atm, so we make a rule of three.

1.013 bar is 1 atm

1.3 bar is (1.3 . 1) /1.013 = 1.28 atm

1.28atm . 15L = n . 0.082 . T

We must convert the mass to moles ( mass / molar mass)

20 g / 30 g / mol = 0.666 moles

1.28atm . 15L = 0.666 mol . 0.082 . T

(1.28 atm . 15L) / (0.666 mol . 0.082) = T

315.5 K = T

As this is absolute temperature we must convert to °C

315.5 K - 273= 42.5 °C

The formation of tert-butanol is described by the following chemical equation:
fomenos

Answer:

Second step

(CH3)3C+ (aq) + OH^-(aq) ------->(CH3)3COH(aq)

Explanation:

This reaction involves;

First the ionization of the tertiary halide to firm a carbocation

Secondly the attack of the hydroxide ion on the carbocation to form tert-butanol

First step;

(CH3)3CBr (aq) → (CH3)3C+ (aq) + Br- (aq)

Second step

(CH3)3C+ (aq) + OH^-(aq) ------->(CH3)3COH(aq)

This second step completes the reaction mechanism.

Explain how glia function within the nervous system.
vovikov84 [41]

Answer:

In the central nervous system, about 90 percent of the cells are glia. Originally, the glia was considered to be passive cells, that is, which only functions to support the nerve cells physically, thus, the term glia is used, which means glue.  

However, the glia plays an essential function in various homeostatic procedures and also at the time of development. The four prime kinds of glia prevail, that is, oligodendrocytes, astrocytes, microglia, and ependymal cells. The glial cells are also known as the supporting cells of the nervous system.  

The prime functions of glial cells are to provide oxygen and nutrients to the neurons, to envelope neurons and hold them in position, to eradicate and remove the carcasses of the dead neurons, and to insulate one neuron from another.
