How many total atoms are in 0.380 g of P2O5

Chemistry
1 answer:
pogonyaev3 years ago
7 0
The gram formula mass of P2O5 is 31*2 + 16*5 =142. The mole number of P2O5 is 0.380/142=0.00268 mol. There is 7 atom in one P2O5 molecule. And there is 6.02 * 10^23 molecule per mol. So the answer is 1.13*10^22 atoms.

What does a high melting point temperature indicate about a substance?
Lana71 [14]

Answer:

B) Temperature, measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature). Temperature is not the equivalent of the energy of a thermodynamic system; e.g., a burning match is at a much higher temperature than an iceberg, but the total heat energy contained in an iceberg is much greater than the energy contained in a match. Temperature, similar to pressure or density, is called an intensive property—one that is independent of the quantity of matter being considered—as distinguished from extensive properties, such as mass or volume.

Most modern thermometers are graduated with both the Celsius temperature scale and the Fahrenheit temperature scale.

Three temperature scales are in general use today. The Fahrenheit (°F) temperature scale is used in the United States and a few other English-speaking countries. The Celsius (°C) temperature scale is standard in virtually all countries that have adopted the metric system of measurement, and it is widely used in the sciences. The Kelvin (K) scale, an absolute temperature scale (obtained by shifting the Celsius scale by −273.15° so that absolute zero coincides with 0 K), is recognized as the international standard for scientific temperature measurement.

Bernoulli model of gas pressureAs conceived by Daniel Bernoulli in Hydrodynamica (1738), gases consist of numerous particles in rapid, random motion. He assumed that the pressure of a gas is produced by the direct impact of the particles on the walls of the container.

In certain fields of engineering, another absolute temperature scale, the Rankine scale (see William Rankine), is preferred over the Kelvin scale. Its unit of measure—the degree Rankine (°R)—equals the Fahrenheit degree, as the kelvin equals one Celsius degree.

The Réaumur (°Re) temperature scale (or octogesimal division) was widely used in parts of Europe in the 18th and 19th centuries; it later was used primarily to measure the temperature of mixtures during brewing, of syrups in the production of certain food products, and of milk during cheese making.

What happens when one freezes salt water?
abruzzese [7]
The answer is B.

The solvent is the part of solution in which the solute is dissolved. Salt, being the solute, makes it harder for water to crystallize into a formal lattice, requiring a lower temperature to trigger the freezing into an irregular structure.
