Liquid X is known to have a lower viscosity and lower surface tension than Liquid Y Use these facts to predict the result of eac

h experiment in the table below, if you can. experiment predicted outcome O mx will be greater than my O mx will be less than my O Ill y will be equal to my Wax-coated particles carefully put onto the surface of Liquid X or Liquid Y will stay on the surface, if the particles are small enough. The heaviest mass of particle x and my that will stay on each liquid's surface without sinking are measured. It's impossible to predict whether mx or my will be greater without more information. OFx will be greater than F)y 15.0 mL of Liquid X are poured into a beaker, and 15.0 mL of Liquid Y are poured FX will be less than Fr into an identical beaker. Stirrers in each beaker are connected to motors, and thewill be equal to P forces Fx and Fy needed to stir each liquid It's impossible to predict whether Fr or F will at a constant rate are measured. be greater without more information.

Density=mass/volume=100g/20cm^3=5g/cm^3. The brick will fall in the lake, because its density is higher than that of water (1g/cm^3).

Which of the following reactions is possible according to Dalton's atomic theory? View Available Hint(s) Which of the following
finlep [7]

Answer:

N2+O2→2NO

Explanation:

Dalton’s atomic theory is based on law of constant composition and law of conservation of mass.

One of the postulates of this theory is that rearrangement of atoms occurs during a chemical reaction. In other words, only rearrangement of elements occurs during a chemical reaction and elements remain the same.

So, among the given, the following reaction undergoes rearrangement of elements.

N2+O2→2NO

SO, only the above reaction is possible as per Dalton’s atomic theory.

What is the "magic number' of valence electrons? How does this influence the type of bonds formed by various combinations of
svp [43]

Magic number is any number in electron shells that suggest stability. It corresponds to total number of electrons in filled electron shells.

If an electron is having magic number, then it forms stable bonds.

Explanation:

The magic numbers are 2,10,18,36,54, 86 and 126. This refers to the total number of electrons that an electron can have when it is completely filled.

Atomic nuclei which carries either of these nucleons have high binding energy as compared to others. Hence, they have high stability. Bonds in such elements are more strong.

Radioactive decay of such elements is very slow.

Eugene Winger coined the term "magic number".
