Chemistry

guajiro [1.7K]3 years ago
5 0

Answer:

Dominant traits are always expressed when the connected allele is dominant, even if only one copy exists. Recessive traits are expressed only if both the connected alleles are recessive.

Explanation:

Freckles, cleft chin and dimples are all examples of a dominant trait.

Alexeev081 [22]

Answer:

A crystalline solid

Explanation:

Most solids form with a regular arrangement of their particles because the overall attractive interactions between particles are maximized, and the total intermolecular energy is minimized, when the particles pack in the most efficient manner. The regular arrangement at an atomic level is often reflected at a macroscopic level.  Liquids dont use to have this kind of arrangements or shapes.

Muszę napisać wzór sumatryczny wysyłam załącznik
ioda

Cześć, nie mówię po polsku, więc zrobiłem to w Tłumaczu Google, więc przepraszam, jeśli coś brzmi śmiesznie.

chlor (VII) i tlen - ten wzór to CI_{2} O_{7}, a tlenek chloru jest bezwodnikiem kwasu nadchlorowego.

węgiel i wodór - wzór na węgiel i wodór to CnH2n + 2), jest to związek organiczny, a niższa klasyfikacja jest taka, że jest to również węglowodór aromatyczny.

Mam nadzieję, że to pomoże, błogosławionego i cudownego dnia! :-)

Problem PageQuestion A student prepares a aqueous solution of butanoic acid . Calculate the fraction of butanoic acid that is in
Yanka [14]

Answer:

Incomplete question: A student prepares a 0.54 mM aqueous solution of butanoic acid...

The answer is: The percentage of dissociation is 15.4%

Explanation:

Given:

Ka = 1.51x10⁻⁵

Concentration = 0.54 mM = 0.54x10⁻³M

The reaction is:

                   C₄H₈O₂               =             C₄H₇O₂⁻          +           H⁺

I                    0.54x10⁻³                             0                                0

E                   0.54x10⁻³(1-x)                      0.54x10⁻³x                0.54x10⁻³x

Where x is the degree of dissociation

Ka=\frac{[H^{+}][C_{4}H_{7}O_{2}^{-}     }{[C_{4}H_{8}O_{2}   } \\1.51x10^{-5} =\frac{0.54x10^{-3}x^{2}  }{1-x} \\x^{2} +0.028x-0.028=0\\x_{1} =0.154\\x_{2} =-0.182

We will choose the positive value

x = 0.154

The percentage of dissociation is 15.4%

Molecules are…<br><br> A) mixtures<br> B) a pure substance <br> C) not a pure substance
Anna [14]

Molecules are pure substances.  This is because a molecule has a set ratio of elements in order to make that compound have the same properties.


For example:

Water is H₂O.  Always.  There is no alternate water formula.

Sand however, is a mixture, who knows exactly what is in sand, and how much of it is in there.
