The oxygen atom would have the greatest velocity due to its smaller atomic mass. It takes more force to move larger objects, so applying the same amount of force to a smaller object would move it further and faster than applying the same force to a larger object.

In a 51.0-g aqueous solution of methanol ch4o the mole fraction of methanol is 0.270. what is the mass of each component?

gladu [14]

Mole fraction<span> is another way of expressing the concentration of a solution or mixture. It is equal to the </span>moles<span> of one component divided by the total </span><span>moles.

mass CH4O = 0.270 (51) = 13.77 g methanol

water = 51 - 13.77 = 37.23 g water

Hope this answers the question. Have a nice day.</span>

Element A has an electronegativity of 0.8 and element B has an electronegativity of 3.0. Which statement best describes the bond

Advocard [28]

Answer:

C) The compound is largely ionic with A as the cation.

Explanation:

Pulings proposed the method to determine if the compound is ionic in nature or covalent in nature , by finding the difference between the electronegativity of the respective cation and anion .

The ion with higher electronegativity is the anion and the ion with lower electronegativity is the cation.

The electronegativity difference above 1.7 make the compound ionic in nature.

Hence, from the question ,

A is the cation and B is the anion.

And the electronegativity difference above 1.7 so the compound is ionic in nature.

Which missing item would complete this beta decay reaction?<br> PLATO

goldfiish [28.3K]

Answer: $_{-1}^0\beta$

Explanation:

General representation of an element is given as: $_Z^A\textrm{X}$

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

Beta decay : In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.

$_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta$
