The state of water is determined solely by the conditions of _____.

Chemistry

Arlecino [84]3 years ago

Answer:

The state of water is determined solely by the conditions of pressure and temperature.

Explanation:

Effect of Temperature:

                              Temperature has direct effect on the kinetic energy of water molecules. Greater the Temperature greater is the K.E of molecules and lesser is the intermolecular forces between molecules. Therefore, at temperature below 0 °C water exists in solid state, at temperature in between 0 and 100 °C it exists in liquid state and (at sea level) and above 100 °C it exists in vapor state.

<h3>Answer:</h3>

                 The state of water is determined solely by the conditions of <u>pressure and temperature</u>.

<h3>Explanation:</h3>

Effect of Temperature:

                               Temperature has direct effect on the kinetic energy of water molecules. Greater the Temperature greater is the K.E of molecules and lesser is the intermolecular forces between molecules. Therefore, at temperature below 0 °C water exists in solid state, at temperature in between 0 and 100 °C it exists in liquid state and (at sea level) and above 100 °C it exists in vapor state.

Effect of Pressure:

                              The state of water is also influenced by the external pressure. For example, water can be converted into gas phase by reducing the external pressure (this technique is used in vacuum distillation where solvents are evaporated at temperatures lower than their boiling points) and also, the water can remain in liquid state even above 100 °C if the external pressure is increases (this method is being utilized in daily use pressure cookers).

Compare and contrast between nuclear fission and fusion
Drupady [299]

Both create energy. Both require atoms.

Fission is ripping the atoms apart, fusion is forcing them together. Fission takes less energy because it's easier to rip unstable atoms apart but pushing two atoms that have similar charges together is extremely hard. Fission is currently mainstream on earth, but fusion is known for taking place within stars.

For the reaction
azamat

Answer:

Mass = 5.56 g

Explanation:

Given data:

Mass of Cl₂ = 4.45 g

Mass of NaCl produced = ?

Solution:

Chemical equation:

2Cl₂ + 4NaOH     →   3NaCl + NaClO₂ + 2H₂O

Number of moles of Cl₂:

Number of moles = mass/molar mass

Number of moles = 4.45 g/ 71 g/mol

Number of moles = 0.063 mol

Now we will compare the moles of Cl₂ with NaCl.

                  Cl₂         :         NaCl

                    2          :          3

                 0.063      :        3/2×0.063 =0.095 mol

Mass of NaCl:

Mass = number of moles × molar mass

Mass = 0.095 mol × 58.5 g/mol

Mass = 5.56 g

¿Qué elemento tiene el mismo número de órbitas que el Hidrógeno? ¿Por qué? ¿Tienen propiedades similares, por qué?
Aliun [14]

What element has the same number of orbits as Hydrogen? Why? Do they have similar properties, why?

Answer:

Helium

Explanation:

Helium has the same number of orbitals as hydrogen because they belong to the same period on the periodic table.

Periods are the horizontal arrangement of elements. Elements in the same period are known to have the same number of electronic shell or orbitals.

In period 1 where we have just Hydrogen and Helium, the number of orbitals is 1.

 

For properties of a specie, elements in the same group which are the vertical arrangement of elements have the same properties. Since both Hydrogen and helium are in different groups, their properties differ.
