Determine which compound would raise the boiling point of water the most

1 answer:

8 0

Because all the compounds are at the same concentration, the one that can produce more particles in solution will be the one that will raise the boiling point the most.

A. 2.0 M (NH4)3PO4 will produce 4 particles per molecule formula

plate tectonics

Explanation:

What did Earth look like 250 million years ago? The continents of Earth were clustered together in formation that a scientist named Pangaea.The scientist that named "Pangaea" was a German scientist by the name of Alfred Wegner. He theorized that "Pangaea" split apart and the different landmasses, or continents, drifted to their current locations on the globe. Wegener's theories of plate movement became the basis for the development of the theory of plate tectonics.

The chemical formula for strontium sulfite is SrSO3. TRUE FALSE

VLD [36.1K]

Valency is the number of electrons lost or gained by an atom to attain an stable configuration. Valency is important when writing the formula of chemical compounds in chemistry. Strontium has a valency of 2 while sulfite ion (radicle) has a valency of 2. Therefore, the chemical formula of strontium sulfite is written as SrSO3.

If you need to produce X-ray radiation with a wavelength of 1 Å. a. Through what voltage difference must the electron be acceler

earnstyle [38]

Answer:

12.4×10^3 V

Explanation:

From E=hc/wavelength= eV

The voltage becomes

V= hc/e* wavelength

V= 6.63*10^-34*3*10^8/1.6*10^-19*1*10^-10

Note that the energy of the photon is transferred to the electron. That is the basic assumption we have applied in solving this problem. The kinetic energy of the electron is equal to the product of the electron charge and the acceleration potential.
