Frost refers to solid ice that condenses and forms on surfaces like grass or windows.

Frost refers to a deposit of small white ice crystals formed on solid surfaces when the temperature falls below freezing temperature.

Frost forms when the temperature of the atmosphere is below freezing i.e. < 0°C.

Therefore, frost refers to solid ice that condenses and forms on surfaces like grass or windows.

Answer Explanation:

If it is like H, or O or N or Na or Cl, those are the elements. Those are on the Periodic table. pH is the acidity and basicity of a substance, how acidic or basic(caustic) it is. mol is Moles. kPa is kilopascals. STP is standard temperature and pressure, at 0*C(Celsius), or 273.15 K(Kelvin), and 101,325 pascals, or 101.325 kilopascals.

Avagadro's Number is 6.022x10^23, the number of atoms in a mole. The Ideal Gas Law is P(Pressure in kPa) times V(Volume in L, liters) equals n(number of moles of gas) times R(the universal gas constant, or 8.3145 (L kPa/K mol) or 8.3145 liters kilopascals per Kelvin mole. that is just a few of them.

volume.

The amount of space a material occupies is its volume.

Mass is measured using a scale. Volume is the amount of space matter takes up. Volume can be measured by multiplying the length, width, and height of an object, or by using a measuring cup and seeing how the measurement of water changes in a cup. Density is the amount of matter an object has in a certain space.

Explanation:

Hello there!

In this case, according to the given information, we infer that we need the combined gas law in order to solve this problem:

[tex]\frac{P_2V_2}{T_2}} =\frac{P_1V_1}{T_1}}[/tex]

Thus, by suing the temperatures in Kelvins, we can solve for the final volume as shown below:

[tex]V_2 =\frac{P_1V_1T_2}{T_1P_2}}\\\\V_2 =\frac{(760mmHg)(22.4L)(232K)}{(273K)(805mmHg)} \\\\V_2=18.0L[/tex]

Answer:

When a saturated solution at a high temperature is cooled, why is the solution separated as a solid? When a saturated solution at a high temperature is cooled, inter molecular space between the molecules of the solution decreases. As a result, no more solute can remain in a solution separating out as a solid crystal.

Explanation:

Answer:

(β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is converted into a neutron by the emission of a positron with a neutrino in so-called positron emission.

Explanation:

Answer:

Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. ... In beta plus decay, a proton decays into a neutron, a positron, and a neutrino: p Æ n + e+ +n.

Answer: Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms.

Soil structure affects plant growth in many, often surprising, ways. The most obvious effects are on root growth, which is strongly inhibited by hard soil, and which in turn influences the ability of the root system to extract adequate water and nutrients from the soil.

Answer:

[tex]\boxed {\boxed {\sf 421,786.7818 \ mol \ H_2O}}[/tex]

Explanation:

We are asked to convert from molecules of water to moles.

1 mole of any substance contains the same number of particles (atoms, molecules, formula units, etc). This is Avogadro's Number: 6.022*10²³. In this problem, the particles are molecules of water.

Use Avogadro's Number to make a ratio.

[tex]\frac {6.022 *10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O}[/tex]

Multiply by the number of molecules given: 2.54 *10²⁹

[tex]2.54 *10^{29} \ molecules \ H_2O \times \frac {6.022 *10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O}[/tex]

Flip the ratio so the units of molecules of water cancel.

[tex]2.54 *10^{29} \ molecules \ H_2O \times \frac {1 \ mol \ H_2O}{6.022 *10^{23} \ molecules \ H_2O}[/tex]

[tex]2.54 *10^{29} \times \frac {1 \ mol \ H_2O}{6.022 *10^{23} }[/tex]

Condense the problem into 1 fraction.

[tex]\frac {2.54 *10^{29} }{6.022 *10^{23} }\ mol \ H_2O[/tex]

[tex]421786.7818 \ mol \ H_2O[/tex]

2.54 *10²⁹ molecules of water are 421, 786.7818 moles of water.

All of these answers are correct.

Explanation:

They are all correct because producers make their food(energy) through photosynthesis, they provide food to herbivores and therefore the rest of the food chain, and without them, the food chain would collapse and all the consumers would starve.
