(H+)(OH-) = Kw
kw=  1 x10^-14
OH-=  1   x10 ^-11
(H+)=  KW / OH-

concentration   of H+  = (1x10^-14) /.(1  x 10 ^-11)   =  1  x10  ^-3

Ph=  -log (H+)

PH=-log (  1  x  10  ^-3)  =  3  therefore  the    solution  is  acidic  since  the  PH   less than  7

What is the name of the compound with the formula NH HCO3 ?
svet-max [94.6K]

Answer:

Acid ammonium carbonate // Ammonium bicarbonate.

Explanation:

Hello, a 4 is missing in the fist H, thus:

NH_4HCO_3

The presence of the hydrogen between the ammonium and the carbonates characterizes the salt as an acid salt, so you could name it as acid ammonium carbonate or ammonium bicarbonate (similar to the sodium bicarbonate which is NaHCO_3).

Best regards.

Be sure to answer all parts. find the most acidic hydrogen in tert−butyl methyl ketone and write a chemical equation for the pro
sleet_krkn [62]
Those Hydrogen atoms which are present at alpha position to carbonyl group are mildly acidic in nature. When such acidic proton containing carbonyl compounds are treated with strong base, they yield enolates. The negative charge created on alpha carbon resonates and shifts to carbonyl oxygen resulting in formation of carbon double bond carbon.

In <span>tert−butyl methyl ketone there are two carbons at each alpha position. Among these two carbons only methyl carbon contains hydrogen atoms while the second one is bonded to further three carbons making it Quaternary carbon. The base abstracts proton from methyl group and enolate is formed. 

</span>tert−butyl methyl ketone in this case acts as acid, Hydroxyl ion acts as base, while the enolate generated is the conjugate base of <span>tert−butyl methyl ketone and Water produced is the conjugate acid of hydroxide ion.</span>

Calculate the inner diameter of the steam tube between the boiler and the high pressure turbine if the average velocity of the s
stich3 [128]

Answer:

The inner diameter of the steam tube is 0.1185 m.

Explanation:

m=\rho \times A\times v=\frac{1}{V}\times A\times v

m = mass flow rate

\rho = density of the liquid

V=specific volume =\frac{1}{\rho }

v = velocity of the liquid

A = area of cross-section

Diameter of the cross-section = d = 2r

Given: m = 18 kg/s, v = 60 m/s,A=?, V = 0.036793 m^3/kg

18 kg/s=\frac{1}{0.036793 m^3/kg}\times A\times 60 m/s

A=0.0110379 m^2

Area of the inner cross section = \pi r^2=\pi \frac{d^2}{4}

\pi \frac{d^2}{4}=0.0110379 m^2

d = 0.1185 m

The inner diameter of the steam tube is 0.1185 m.
